COMPUTER BACKUPS

by: Jack Back
COMPUTERS AND HALLOWEEN, DO THEY MIX?

Computer backup is so important to your computer that to ignore it is to risk its damnation.

Computers require care and feeding. They require that you attend to their needs. If you don't, then they will most surely be sent to Hell.

Halloween means Hell. What! What do you mean that Halloween means Hell?

Well, if your computer is given the option of trick or treat, which will it accept? Will it accept the trick or the treat? What do you think?

Halloween is the time that computers are subject to tricks or treats. Did you know that more computers fail on Halloween than any other day of the year? That’s right. It’s true (smile). Your computer is in danger! Protect it. Do your computer backups.

Back to the Hell thing. Hell you say? Yep. Well, what do you mean by Hell?

Computer hell is the place for computers without computer backup. The failure to perform hard drive backup means that you are playing Russian Roulette with your data. Data needs your protection. Failure to protect your data may cause your home or business records to be sent to Hell.

Hell in this instance is for the records and files that cannot be resurrected. Resurrected you say, what does that mean?

It means that without computer backup as a source of salvation then the files can safely enjoy eternal oblivion. Oblivion you say, what does that mean? That means they are eternally lost from computer resurrection.

Is there any mercy for my precious files, you ask?

Why yes there is. Would like to know what the mercy for your files is? Yes! Yes! You say.

OK boys and girls listen carefully. The salvation, mercy, resurrection and redemption of your files lies in regular and consistent and persistent computer backup.

If you backup your computer consistently and persistently your files will be resurrected and saved from accidental deletion, hard drive failure and those nasty things like fire, flood, theft, earthquake, hurricanes, tornados and the like!

Computer backup is the key to your data's salvation!

Do your computer backups boys and girls.

Milk and cookies will be served in the pantry.

Trick or treat for your computer backup?

Computer Accessories We All Want For Our New Computer!

by: Bonnie Archer
Printers
A computer accessory we all need. From inexpensive ink jets to monochrome and color lasers, different printers are designed to do different jobs with your computer. You will have a few choices to make when getting your new printer: price, speed, and print quality are the main ones. Ink jet printers and digital cameras are changing how we print photographs. Load your printer up with special photo inks and paper and ink jet/bubble jet printers have become one of the best options for transforming a digital image into a photograph! For speed and razor sharp text the monochrome laser printers are fantastic.

Scanner
This computer accessory is for input into your computer. Graphic designers will use a scanner often to input pictures etc. If you don't have a digital camera a scanner is the only other way to get pictures into your computer to email, manipulate, add to cards, etc.

Speakers
These are computer accessories that most computers come equipped with. But some people like 'game players' want to upgrade for surround sound. You will find many different versions and brands.

Keyboard and Mouse
These are also computer accessories that usually come with a computer system. Although most people will have to purchase new ones during the life of their computer. This is because they do not last as long as the computer system itself. Of course, it is dependent on how much you use them, how rough you are on them, and how clean you keep them.

Choosing the best computer model

by: Dr. Yuri Iserlis

Computer Families and Models
Many computer manufacturers, especially such computer giants as IBM, Dell, Gateway, Sony, Apple, etc. issue families (series) of computers. Models of computers in each series have either the same principle of design, or same processor, or have been given diapason of performances. The series can include a base model, and several derivative models. Usually for each type of computer, manufacturers issue series that generally can be divided into 3-4 categories: budget-friendly (at low price), mid-range (at middle price), cutting-edge and ultimate performance (at high, and very high prices). IBM, Gateway, Dell and Apple issue computer families not only for Home and Home office, but also for Small, Mid size or Large Businesses. These families can also include the network optimized series.
The needed features
First of all, you have to make a preliminary analysis of your needs to pick a type of computer, and a zone where you might search this computer, for example, for Home or for Small Business. But it is not sufficient.
(see: http://www.cleverace.com/Choosing_type_of_computer.htm)
To understand what kind of computer to buy, you additionally have to determine what computer performance you need: the type of processor, speed, size of memory, type of video and audio cards, type of case, and so on. You can select one from two ways: 1 - to formulate your needs in the process of searching, 2 - to compile a list a hardware requirement for the programs you might want to run
(see: http://www.cleverace.com/Choosing_best_computer_model2.htm.)
Preliminary selection:
To select a computer family, you have to choose one, which the features match your wishes. Such families can be several. Next procedures are to find the best computer family and best model of computer belonging to this family. If you know the features you need, you can identify the name of the computer family. For this goal you have to use for example, a Table of Features comparison for base models of computer families. For example, according to this Table, if you know that you need a computer only for simple text editing and emailing, your choice is Budget-Friendly Series. On the other hand, if you need for realization of your tasks a computer from Cutting-Edge series , but it is not affordable, your choice can be like a computer from Mid-range series plus a customization (perhaps, when you can better afford it).
To accelerate the search for the preliminary selection, you can find comparison information about the different types of computers with the help a comparison-shopping search engine. It allows you quickly to find the needed products sold by online stores, small businesses, and individuals in diapason of affordable prices. Search can be done by Brand, by Price, by Processor speed, etc. To find what you need, see: http://www.nextag.com/serv/cleverace/buyer/outpdir.jsp
Generally, a preliminary selection can be executed on the basis of not only cost and main functions, but also on an evaluation of convenience of use, warranties, and so on. This kind of selection you can make for computer families of different manufacturers for example, for 3 or 4 families of computer giants. Some companies, such as Gateway, gives to a buyer an opportunity to compare preliminary selected models of computers with "compare" option.
Final selection.
To find the optimal model for yourself, you may make the final selection from the preliminary chosen models. It is much easier to compare 3-4 models, than more than 5 million variants that are available on the Computer Market at the beginning of your search.
Custom built model
If you can't find a computer with the needed performances among the available computers, you need to select a vendor and to order a custom built computer.
See: http://www.cleverace.com/Ordering_custom_built_computers.htm.
Discount
Keep in mind, you can find a cheaper computer for the same model on the Discount Market, because some online stores, especially the computer giants, suggest coupons; or discounts, such as $20 off, when you spend $150 or more; free shipping; free printer; and so on.
See: http://www.cleverace.com/discount_market.htm

Buying a Personal Computer

by: Bonnie Archer

For so many people the computer world is a seeming unsolvable jungle filled with mysterious words. Here is a guide to help you understand the personal computer and to give you the information needed to make a shopping decision you can live with so you can enjoy your PC for years to come.

Not long ago the average 'cheaper' personal computer cost was about $1500. - $2000. And this price did not necessarily include the power to edit videos, pictures, or play games. For that you would have had to spend more on upgrades. Now things such as video editing are standard on the newest personal computers. PC’s have become less expensive than ever before and they come with more capabilities than ever.

The personal computer (PC) you purchase will depend upon what it will be used for. So will you surf the Internet and email, working in spreadsheets, playing video games? Who is using the PC and what are there interests? More than likely you will have to accommodate a combination of these or maybe even all of them.

Many personal computers (PC) today offer very similar capabilities so your main decision will be based upon which specialties your personal needs present. For instance if you are mainly interested in gaming than you will be sure to spend more for a good 3D graphics card. If you want to make music you will need a good sound card. If you work all day on your computer or use it for photo editing you will want to invest in a better monitor. Also, make sure your PC has enough memory to quickly work the tasks you have planed.

For the best value for your dollar spend your money on the personal computer components that will best suit your needs.

Build Your Own Computer or Buy?

by: Ron King
Just look inside a computer case. At first glance, all those wires and components can look terrifyingly complex. And thinking about putting them all together by yourself may seem impossible.

. Not to worry! Even though they are the products of advanced technology, the various pieces of a personal computer (PC) fit together with simple connections. If you can use a screwdriver and follow simple instructions, you can build your own PC.

Don't be intimidated by the task of connecting the computer components together. Many of the internal connections are molded so that it is impossible to fit them together the wrong way. If you have ever assembled a child's toy, you are more than capable of assembling a computer.


Advantages Of Building Your Own

You are probably asking yourself why anyone would bother to build a PC. After all, you can buy a cheap computer in almost any retail store.

If cost is your only consideration, you probably are better off buying one of those cheap machines. But if you have any special requirements for software or hardware, you’ll benefit from the total control over the type and quality of components you get from building your own PC.

You can save some money, too. Although you probably can't match the price of the cheapest preassembled PC, once you begin adding on the inevitable customized hardware, the costs go up anyway. Suddenly building your own computer starts looking cheaper. And don't forget--those super-cheap PCs are bare-boned systems. Unless you need a computer only for basic word processing and e-mail, you will probably have to upgrade anyway.

Building your own PC can be a great learning experience. You will gain a better understanding of how the various components work together, knowledge that can be useful for troubleshooting. If your computer ever breaks down, you may be able to pinpoint the problem and fix it yourself, saving money on expensive repair bills.

You are virtually guaranteed to get the best computer when you build your own system. Big retailers often use cheaper OEM (Original Equipment Manufacturer) components to cut down on costs. Components like these can compromise the performance of a computer system. Although you can buy OEM components yourself, the trade-off in reliability and stability is usually not worth it. Brand name components are just a bit more expensive, but are well worth the cost.

Disadvantages

The major disadvantage in building your own PC is that you don't get a system-wide warranty. For example, if a malfunctioning motherboard fries your memory chips, you may not be able to get compensation for the damaged memory. If something like this happens with a store-bought system you could probably get the whole computer repaired under the warranty.

However, if you buy all your components at the same time from the same retailer, you are more likely to be compensated for this kind of situation.

Time is, of course, a factor. But it is educational time. And if you enjoy tinkering at all, it counts as fun time as well.


The Bottom Line

Building your own PC has a lot to offer. You'll be assured of getting the best components available, which translates to the best and most reliable computer for your money. You will learn about computer components and how to choose parts with the best performance. When it comes to servicing your computer, you may be able to solve and fix the problem yourself.

Oh, and one final advantage. The bragging rights of telling your friends that you built your own computer. Priceless!

Barebones Systems: Alternatives to Buying Discount Computers
by: Nicky Pilkington
Buying discount computers is something easy to do nowadays that computer prices have dropped. Despite the low prices, you may still find it difficult to settle on a single computer. Computers are built with so many varying features that finding exactly the right one for you may be difficult. Building your own system from a barebones system is an option to buying discount computers that will enable you to get what you want exactly and still enables you to save money.

Don’t think you can build a computer system? It’s true that building a computer system takes some time and a bit of knowledge about how computers work. When you start the building process with barebones systems you deduct some of the complication associated with building a computer system. Barebones systems have the basic components that you need to get started with building a computer system. Most of these systems include a motherboard, CPU (computer processing unit), and power supply encased in a computer case. Choosing a barebones systems is similar to buying discount computers. You will need to determine your needs to find just the right system for you.

Barebones systems are typically classified according to what they offer. While they contain the same basic components, the components enable you to perform different levels of tasks. Low-level barebones systems, which range in price from $100 to $200, will have components that are not as advanced as those in high-end barebones systems. Of the components in a barebones system, the processor is your main concern. There are basically two types of processors: Pentium and Athlon.

There is much debate about which processor is the best. Pentium is probably the most popular name in processors. Its name is synonymous with speed and power. With the introduction of the Pentium 4 processor, Intel suggests that pure multi-tasking is possible. Athlon may not be as popular with general consumers, but those individuals who understand the components of processors, such as clock speed, know that Athlon is at the very least in step with what the Pentium processor offers. Athlon 64, the most current processor that AMD offers

Once you select the barebones system with the essentials you need, you basically upgrade the barebones system to include the additional parts you need to create your ideal computer. After the processor, you want to consider memory, a hard-drive, and CD/DVD writer. Essentially, just as with the processor, you will need to determine what tasks you intend to perform with the computer. As a rule of thumb when buying discount components, you don’t want to build a system with the most high-end components. For starters, you will end up spending a significant amount of money (negates the purpose of choosing an alternative to buying discount computers) and the components will more than likely soon be replaced with a more high-end component.

All About Computer Viruses
by Kara Glover
kara333@earthlink.net

Your computer is as slow as molasses. Your mouse freezes every 15 minutes, and that Microsoft Word program just won’t seem to open.

You might have a virus.

Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway?

Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses don’t bother to seek your permission at all! Very invasive.

In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guy’s consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc.

In this article, though, we’re not talking about the good guys, or the agents. We’ll be talking about the bad guys, the viruses.

A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program.

When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave.

This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp.

Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but they’re not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.)

These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks.

As far as web browsers are concerned, Microsoft’s Internet Explorer takes most of the heat for spreading viruses because it’s used by more people for web surfing than any other browser.

Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said.

For instance, let’s say you go to a website in IE you have every reason to think is safe, Nachenberg said.

But unfortunately it isn’t. It has virus code hidden in its background that IE isn’t protecting you from. While you’re looking at the site, the virus is downloaded onto your computer, he said. That’s one way of catching a nasty virus.

During the past two years, another prevalent way to catch a virus has been through downloads computer users share with one another, mostly on music sharing sites, Kuo said. On Limewire or Kazaa, for instance, teenagers or other music enthusiasts might think they’re downloading that latest Justin Timberlake song, when in reality they’re downloading a virus straight into their computer. It’s easy for a virus writer to put a download with a virus on one of these sites because everyone’s sharing with everyone else anyway.

Here’s one you might not have thought of. If you use Outlook or Outlook Express to send and receive email, do you have a preview pane below your list of emails that shows the contents of the email you have highlighted? If so, you may be putting yourself at risk.

Some viruses, though a small percentage according to Nachenberg, are inserted straight into emails themselves.

Forget opening the attachment. All you have to do is view the email to potentially get a virus, Kuo added. For instance, have you ever opened or viewed an email that states it’s “loading”? Well, once everything is “loaded,” a virus in the email might just load onto your computer.

So if I were you, I’d click on View on the toolbar in your Outlook or Outlook Express and close the preview pane. (You have to click on View and then Layout in Outlook Express.)

On a network at work? You could get a virus that way. Worms are viruses that come into your computer via networks, Kuo said. They travel from machine to machine and, unlike, the classic viruses, they attack the machine itself rather than individual files.

Worms sit in your working memory, or RAM, Nachenberg said.

OK, so we’ve talked about how the viruses get into a computer. How do they cause so much damage once they’re there?

Let’s say you’ve caught a classic virus, one that replicates and attacks various files on your computer. Let’s go back to the example of the virus that initially infects your Microsoft Word program.

Well, it might eventually cause that program to crash, Nachenberg said. It also might cause damage to your computer as it looks for new targets to infect.
This process of infecting targets and looking for new ones could eventually use up your computer’s ability to function, he said.

Often the destruction a virus causes is pegged to a certain event or date and time, called a trigger. For instance, a virus could be programmed to lay dormant until January 28. When that date rolls around, though, it may be programmed to do something as innocuous but annoying as splash popups on your screen, or something as severe as reformat your computer’s hard drive, Nachenberg said.

There are other potential reasons, though, for a virus to cause your computer to be acting slow or in weird ways. And that leads us to a new segment – the reason virus writers would want to waste their time creating viruses in the first place.

The majority of viruses are still written by teenagers looking for some notoriety, Nachenberg said. But a growing segment of the virus-writing population has other intentions in mind.

For these other intentions, we first need to explain the “backdoor” concept.

The sole purpose of some viruses is to create a vulnerability in your computer. Once it creates this hole of sorts, or backdoor, it signals home to mama or dada virus writer (kind of like in E.T.). Once the virus writer receives the signal, they can use and abuse your computer to their own likings.

Trojans are sometimes used to open backdoors. In fact that is usually their sole purpose, Kuo said.

Trojans are pieces of code you might download onto your computer, say, from a newsgroup. As in the Trojan War they are named after, they are usually disguised as innocuous pieces of code. But Trojans aren’t considered viruses because they don’t replicate.

Now back to the real viruses. Let’s say we have Joe Shmo virus writer. He sends out a virus that ends up infecting a thousand machines. But he doesn’t want the feds on his case. So he instructs the viruses on the various machines to send their signals, not of course to his computer, but to a place that can’t be traced. Hotmail email happens to be an example of one such place, Kuo said.

OK, so the virus writers now control these computers. What will they use them for?
One use is to send spam. Once that backdoor is open, they bounce spam off of those computers and send it to other machines, Nachenberg said.

That’s right. Some spam you have in your email right now may have been originally sent to other innocent computers before it came to yours so that it could remain in disguise. If the authorities could track down the original senders of spam, they could crack down on spam itself. Spam senders don’t want that.

Ever heard of phishing emails? Those are the ones that purport to be from your internet service provider or bank. They typically request some information from you, like your credit card number. The problem is, they’re NOT from your internet service provider or your bank. They’re from evil people after your credit card number! Well, these emails are often sent the same way spam is sent, by sending them via innocent computers.

Of course makers of anti-virus software use a variety of methods to combat the onslaught of viruses. Norton, for instance, uses signature scanning, Nachenberg said.

Signature scanning is similar to the process of looking for DNA fingerprints, he said. Norton examines programming code to find what viruses are made of. It adds those bad instructions it finds to its large database of other bad code. Then it uses this vast database to seek out and match the code in it with similar code in your computer. When it finds such virus code, it lets you know!

A Guide To Basic Computer Terminology

by: Bonnie Archer
Ram? Mouse? One is an animal and one is a rodent right? Ram...that is the zodiac sign for Aries... If this is what these words mean to you than you can surely use this quick glossary of computer terminology. It would be a good idea to read through them before purchasing a computer because these are things you should know about first. If you already have a computer then these computer terms can help you know what to do if your new computer equipment is unfamiliar. Also, this computer terminology can help you if you have to call in for technical help Okay lets go!

Cache: Cache is another type of memory kindred to RAM. The computer uses cache to quickly move data between the RAM and the CPU.

CD-ROM Drive: Most new computers now come with a CD-ROM drive as standard equipment. A CD-ROM drive reads data from a disc. These CDs look like a music CD, but hold data instead of music. CD-ROMs also contain games, dictionaries, recipe files, and lots of other things that you can load onto your computer.

CPU: The CPU, or central processing unit, is the brains of the computer. Most new Windows based programs use a Pentium processor or a AMD Athlon XP. New Macs use a different type of CPU called Power PC.

Disk Drive:Virtually all computers come with a disk drive that can read and save information on portable diskettes, also called floppy disks. You can use floppy disks to save information or to load new software onto your computer.

Hard Drive: The hard drive is also called the hard disk. You'll probably never see it because it is nestled inside your computer. It's the computer's electronic filling cabinet, and it stores the computer's operating system, files, programs and documents.

Keyboard: Just like a typewriter keyboard, this device is the primary way of inputting data into the computer programs.

Megahertz (MHz): This is the clock speed of the microprocessor. The higher the number, the quicker the information is processed. MHz relates to how many millions of instructions can be processed per second.

Memory:This is the circuitry or device that holds information in an electrical or magnetic form. There is read-only memory (ROM), which is information primarily stored on a disk, and random-access memory (RAM), which is chip-based storage inside the computer. Memory is typically measured in megabytes (MBs).

Modem:This mechanism connects a computer to a phone line so information can be sent from one computer to another or the user can access an on-line service or the Internet. In view of the popularity of the Internet, a modem is now considered basic equipment and comes on practically all-new computers. Most modems come with fax capabilities.

Monitor: An output device that allows you to see what you are doing (it is what you are looking into right now to see this). Most computers come with 14 or 15-inch monitors. This size is good for most people's needs. Larger 17 or 21-inch monitors also are available, but may cost more. Myself, I prefer the 17-inch.

Motherboard:The motherboard is the circuit board that everything in the computer plugs into. The CPU, RAM and cache all plug into the motherboard.

Mouse: The mouse is another input device that makes getting around in your computer easier. It is a handheld object that is good for doing tasks such as moving and pointing to objects on the screen, and can replace the function and control keys of the keyboard. (If you need a lesson on how the mouse works and how to use it click here for a tutorial.)

Printer: A printer is an essential part of the computer if you want a hard copy of your work. There are four types of printers on the market: dot matrix, inkjet, bubble jet and laser. The dot matrix is the most basic. Most inkjets and bubble jets can print color and graphics, and a laser printer offers the best resolution at the highest speed.

RAM:Computers save data in two ways: on the hard drive and in random access memory or internal memory. New computer buyers should look for models with at least 16 MBs of RAM (or more, depending on what types of programs you'll be running). Make sure that the computer can be upgraded.

Scanner:A scanner is a useful accessory to have if you are working with lots of artwork or photos. This device can copy written documents, pictures or photographs directly into your computer. There are three types of scanners: handheld, hopper-feed and flatbed.

Sound Card: This device allows your computer to reproduce music, sounds and voices. Make sure you have a sound card if you're planning to play multimedia games.

Video Card: The video card is the part of the computer that sends the images to the monitor.

Well there you have it, a quick course on computer terms. I hope it has helped to guide you in your purchase of a new computer; or to help you with the one you have.

Build Your Own Computer or Buy?

by: Ron King
Just look inside a computer case. At first glance, all those wires and components can look terrifyingly complex. And thinking about putting them all together by yourself may seem impossible.

Not to worry! Even though they are the products of advanced technology, the various pieces of a personal computer (PC) fit together with simple connections. If you can use a screwdriver and follow simple instructions, you can build your own PC Don't be intimidated by the task of connecting the computer components together. Many of the internal connections are molded so that it is impossible to fit them together the wrong way. If you have ever assembled a child's toy, you are more than capable of assembling a computer.


Advantages Of Building Your Own

You are probably asking yourself why anyone would bother to build a PC. After all, you can buy a cheap computer in almost any retail store.

If cost is your only consideration, you probably are better off buying one of those cheap machines. But if you have any special requirements for software or hardware, you’ll benefit from the total control over the type and quality of components you get from building your own PC.

You can save some money, too. Although you probably can't match the price of the cheapest preassembled PC, once you begin adding on the inevitable customized hardware, the costs go up anyway. Suddenly building your own computer starts looking cheaper. And don't forget--those super-cheap PCs are bare-boned systems. Unless you need a computer only for basic word processing and e-mail, you will probably have to upgrade anyway.

Building your own PC can be a great learning experience. You will gain a better understanding of how the various components work together, knowledge that can be useful for troubleshooting. If your computer ever breaks down, you may be able to pinpoint the problem and fix it yourself, saving money on expensive repair bills.

You are virtually guaranteed to get the best computer when you build your own system. Big retailers often use cheaper OEM (Original Equipment Manufacturer) components to cut down on costs. Components like these can compromise the performance of a computer system. Although you can buy OEM components yourself, the trade-off in reliability and stability is usually not worth it. Brand name components are just a bit more expensive, but are well worth the cost.

Disadvantages

The major disadvantage in building your own PC is that you don't get a system-wide warranty. For example, if a malfunctioning motherboard fries your memory chips, you may not be able to get compensation for the damaged memory. If something like this happens with a store-bought system you could probably get the whole computer repaired under the warranty.

However, if you buy all your components at the same time from the same retailer, you are more likely to be compensated for this kind of situation.

Time is, of course, a factor. But it is educational time. And if you enjoy tinkering at all, it counts as fun time as well.


The Bottom Line

Building your own PC has a lot to offer. You'll be assured of getting the best components available, which translates to the best and most reliable computer for your money. You will learn about computer components and how to choose parts with the best performance. When it comes to servicing your computer, you may be able to solve and fix the problem yourself.

Oh, and one final advantage. The bragging rights of telling your friends that you built your own computer. Priceless!

A Basic Introduction To Spyware

by: Philippa Smith

Spyware is the most troublesome software to appear on the
Internet in recent times. When spyware infects a computer
system, it may be relatively harmless or it may be
devastating.

Spyware like coolwebsearch and new.net are capable of
paralyzing a computer system. Laws to regulate spyware are
pending in many states and may take years to enforce.

What Is Spyware?

Spyware is any software that collects information about
computer usage and/or the computer user. It is installed on
one computer and sends information to another computer.
Some spywares like the Weather Bug, Bear Share and Kazaa
are knowingly downloaded and installed by users. Other
spyware is installed without the knowledge or permission of
the user.

How Does Spyware Affect A Computer?

Symptoms of spyware infection includes:

* Very slow system performance while browsing the Internet.
* Your homepage changing mysteriously on its own.
* Excessive appearance of pop-ups, on sites likes Google,
Yahoo and MSN, which don't use them.
* You can only get your browser to visit sites, which are
trying to dupe you into buying spy ware removal software.

Many spyware detection and elimination programs are easily
available for free on the Internet.

How Does One Deal With Spyware?

There are many tools and catalogues available to deal with
spyware. One of these tools is Spybot Search and Destroy.
It scans computers for spyware and harmful programs. It
shows a list of problem areas to the user and allows him to
delete any or all of them.

A user can leave legitimate programs installed by him.
These may include peer-to-peer file sharing software or
software installed to monitor the on-line activities of
children.

A Comprehensive Solution

It may be a good idea for most computer owners to get a
comprehensive PC security solution as a bundle. Norton and
McAfee, now offer a complete security suite consisting of
anti-virus, personal firewall, anti-spam and privacy
offerings, and anti-spy ware.

They are quite easy to install and allow parents to monitor
children who use the computer. There are many threats on
the Internet, from which these suites can protect your
computer.

5 Sure-Fire Tips for Buying a New Computer

by: John Lenaghan

So you're thinking of buying a new computer...

Where do you start? There are so many brands and models of computers available, and it can all be a little overwhelming when you start to look around.

How do you decide what type of computer you need? And perhaps more importantly, how do you decide what the best value is?

I have sold computers professionally for almost 20 years, and there are certain "tricks of the trade" that most computer stores and salespeople use. Knowing these secrets can make your decision easier and will help you buy the right computer for your needs.

1. Buy What You Need, Maybe a Little More

One of the most important things you can do when buying a new computer is make a list of the things that you will be using it for. There are so many different models - with different capabilities - that you can easily buy more, or less, than you really need if you don't.

If this is your first computer, this can be a little tougher. Until you've used a computer, it's hard to know exactly what you might want to do with it beyond the obvious, like connecting to the internet.

Regardless, you should think about some of the things you might want to do. Some possibilities include:

- Connect to the internet
- Play games
- Digital photography
- Digital video
- Type documents
- Accounting
- Design websites
- Programming
- Digital scrapbooking
- Geneology

Some of these things need more power than others. For example, connecting to the internet really doesn't need a lot of power. Even the most basic computer available will probably work just fine.

Digital video and many games need a lot more power. If you don't get a fast enough computer with enough memory, you'll be disappointed with the performance.

Knowing what you're going to be using your computer for will help your salesperson, whether they're on the phone, the internet or standing in front of you, recommend the best system for your needs.

As a general rule you're always better off buying more power than you need rather than less, but buying too much can be a waste of money.

2. Warranty Considerations

Computer warranties are one of the most confusing and obscure parts of your purchase. Most manufacturers have cut back on their customer service to the point where poor service has become a given.

The three most common options are onsite, carry-in or manufacturer's depot service.

Onsite service can be helpful, but think about whether you want to have to be available for a technician to come and diagnose your computer, and possibly have to come back with parts at another time.

Carry in service is a good option, but find out whether the service center is factory authorized for warranty repairs, as well as whether the technicians are all certified.

Shipping your computer to a factory service center can take a long time - sometimes a number of weeks. It also creates risk that your computer will be damaged or even lost in shipping. In some cases, the manufacturer will even replace your computer with another unit and ship it back to you, rather than repairing it. This can result in your losing any information that was on your system and having to reload all your software.

Another aspect of the warranty to find out about is technical support. Find out if the computer manufacturer offers a toll-free phone number and what the quality of service is like.

The better computer salespeople will be honest about this and tell you if a company's service leaves something to be desired. You can also do some research on the internet - most of the computer magazines like PC Magazine and PC World have annual customer service comparisons that rate the larger computer companies.

Always find out how the warranty is handled before making your decision. Even if it doesn't influence your choice, knowing what to expect if something does go wrong will save some nasty surprises down the road.

3. Can You Negotiate the Price Down?

A computer is a relatively large investment - anywhere from a few hundred to a few thousand dollars. Many computer buyers expect that there is a significant amount of "wiggle room" on the price.

The reality is that most computer hardware - the physical pieces like the computer, monitor and printer - is sold at very low profit margins. Often, computer systems are even sold at or below the dealer cost. When you're buying a computer, it never hurts to ask for a better deal, but don't be surprised if you only get a few dollars off, if anything.

Over the close to 20 years I've sold computers, I watched the profit margins go from over 40% to less than 5%. It's almost embarassing to offer a $20 discount on a $2500 computer system, but that could mean the difference between making and losing money on the sale.

What you can do to get the best price is to do some comparison shopping. Most computer stores offer price-matching guarantees, so if you find your computer for less at another store, most dealers will match or beat that price, even if it means they lose money.

4. How Do Computer Stores Make Any Money?

You might be wondering how these computer stores make any money if they're selling computer for so little profit.

Their money is made on add-on items. The highest profit areas in most computer stores are cables and "consumable" products such as printer ink and paper.

Printer ink is a huge money-maker for most computer stores (even more so for the printer manufacturers). Why is this? Once you've bought a printer, you're going to have to replace your ink at some point, and continue to replace it as it runs out.

Most chain computer stores and office supply stores that carry a large selection of ink cartridges make more from ink than they do from the computers themselves.

Cables also have huge markups. A cable that costs the store $2-3 will often sell for $20-30. That's ten times their cost!

If you're buying a new computer, you will likely need to buy some cables. Some items - printers, for example - don't often include the cables needed to hook them up.

Many printers also come with "starter" ink cartridges that are only half-full. You might also want to pick up some extra ink cartridges.

This is where you should be able to negotiate a better price. Don't expect the salesperson to throw them in for nothing, but they should be willing to offer you a better price. After all, if you're happy with their service, you'll probably continue to buy your ink, paper and other products from that store in the future.

5. What Software is Included?

The last secret of buying a new computer has to do with the software that is included. Most new computer systems include quite a few programs and sometimes the value of the software can be quite high.

Something to watch out for when looking at the included software is "trial versions" or "limited editions".

Many programs that are preloaded are either crippled versions that don't have all the features of the full program, or trial versions that will only run for a certain amount of time before they expire.

Computer are often sold with trial versions of the following types of software:

- antivirus
- firewall
- MS Office or other office suites
- Accounting - both business and personal

The computer manufacturers generally don't make it easy to tell whether the software on their systems are trial versions or limited versions. This is a question that you should specifically ask if you can't find the answer in their promotional information.

If you're buying a new computer with trial versions of the software, keep in mind that you will need to pay to continue using it after the trial period is over. This is an added cost that you need to consider as part of your overall budget.

These five "secrets" of buying a new computer are fairly common sense, but they are not always made clear up front. Knowing what to ask will help you in two ways. First, you can be sure you are getting the right computer for your needs.

Second, if the salesperson or company that you're dealing with explains these things to you without being asked, you'll know you're dealing with someone who is honest and upfront.

Knowing you can trust the people you're dealing with is an invaluable feature of your new computer system.

3 Summer Computer Tips

by: Sharron Senter

Written By: Sharron Senter


#1 – Summer Computer Travel
Holiday travelers should be on alert when arriving home from long weekends, such as the Fourth of July, a popular time for computer viruses to spread.

Most computer users have a tendency to turn off their computers when away on trips, which means you’re not getting newly-released anti-virus patches or anti-spyware updates; the two most common areas that cause computers problems. We recommend you update anti-virus and anti-spyware scans before opening e-mail or going online after an extended absence.

We consistently see an increase in calls for virus related problems immediately following long weekends. Avoid the problems altogether by updating your security software before using your computer. For a free listing of viruses, spyware threats and trends, visit: www.VisitingGeeks.com/downloads.htm

#2 -- Should You Leave Your Computer Running?
One question we hear frequently is, "Should I leave my desktop computer on or turn it off?"

There are 2 schools of thought…
Turning it on and off numerous times during the day subjects the microcircuits to flexing and fatigue due to change in temperatures. Over time this could lead to a break in the circuitry and result in system failure.

Leaving the computer on all the time puts excess wear on the mechanical components (the hard drive spindle motor and cooling fans).

Best compromise. First user in the morning turns it on; last user turns it off.

We leave our desktops on all the time allowing for scheduled utility tasks to run during overnight hours. We also restart the systems (to flush the RAM and reset the operating system) on a regular basis and routinely remove the case covers to clean out any dust that may have accumulated, especially around the fans and screens.

#3 -- Stop Popups!
Never click inside the window of a popup. Instead, close it by clicking on the X in the upper right corner. Many people are fooled into installing spyware applications by popups that promise to clean their system. If you receive a message saying it can help, assume it’s spyware and don’t click!

3 Simple Ways To Save A Bunch Of Money When Buying A New Computer!

by: Kris Bickell

Looking to buy a new computer?

Overwhelmed by all of the options available to you?

Stressed by the high cost of computers today?

For most people, buying a new computer does not have to be as stressful as buying a new car. Nor does it have to be as expensive. If you’re like most people, and you have a limited budget for buying a computer, then you need to try to get as much computer for your money as possible.

Here are 3 simple ways anyone can save money when buying a new computer:

1) Shop around for best deal.

Sounds pretty obvious. But many people don’t realize they don’t need the fastest, most expensive computer with the most “extras”. In fact, if you are already using an older computer, even the least expensive new computer will be a big upgrade. If you don’t know a lot about computers, you can learn a lot by shopping around. Ask lots of questions, compare prices, compare features, then find the best price. Shop at your local electronics store, and look for the best deals online. You’ll be surprised at how much money you can save by shopping around!

2) Install your own “extras”

Many computers you will find in a store have a lot of extra software already installed. While this is convenient, it is not always the best way for you to save money. Also, while many of these extras sound good, you don’t always need them. You can often find better deals by shopping around separately for your own software extras (such as a word processor, anti-virus, popup blocker, spyware removal, games, etc). And some of these you can get for free. So before you buy the “fully loaded” computer, ask yourself if you really need all the extras, then shop around to see if you can buy a scaled down computer - and get the extras yourself for much less!

3) Don’t buy extended warranty

If you are not a computer “techie”, the extended warranties offered by the computer retailers often sound like a good idea. After all, who wants to be bothered paying for service on a computer after you buy it. But keep in mind that most computers come with a warranty, and most computer problems will either happen at the beginning (when you still have the warranty in effect) or much later (when it might be cheaper to buy a new computer). Technology changes very quickly these days. So consider whether or not it’s worth the inflated price of the extended warranty. And, if you really feel you need the extended warranty, then ask to purchase it at a lower price. Not all retailers will negotiate on the warranty, but some will. And whether you buy the extended warranty or not, make sure you back up all your files periodically, just in case!

If you have an unlimited budget, consider yourself lucky. And if you do business on the computer, make sure you get what you need, while trying to keep the price down. At any price, buying something that does not fit your needs is not a good deal.

Hope you find these tips helpful, and happy computer shopping!
