Buying DDR memory for your computer

Many aspects of the personal computer have increased in leaps and bounds in terms of performance and what they are capable of doing.

Computer memory, often referred to as Random Access Memory (RAM), has become of greater and greater performance as time has gone on.

One of the famous quotes from back in the eighties was one made by Bill Gates when he said that no one would ever need more than 640KB of memory. Well that has been passed for ages now, with high performance machines sometimes sporting over 1GB of it.

There are many advantages that can be had with more memory. -Programs run faster -Less waiting time for programs to load -More programs can be run at a time -Overall computer speed is increased

Double Data Rate (DDR) memory is the staple of the consumer market. It has taken off due to public demand and now comes quite reasonably priced.

Computers don't generally come with less than 256MB of memory nowadays. My computer after freshly installing Windows 2000 (no, I haven't gone to Windows XP yet) takes about 80MB or memory. That is the very least, with no additional programs or anything else installed. After I have installed all the graphics drivers, Internet connection software for ADSL, virus protection and firewall it takes around 160MB of total memory.

From my previous experience, 256MB will do, but after it becomes quickly filled when running a few programs, Windows reverts to using the hard drive for memory. It's a way to fake more memory, by using the hard drive as a temporary store. 512MB now does it for my needs, but if you run many programs or memory intensive ones, 768MB or even 1GB will do better.

But is memory size the only factor?

An equally important factor is the memory speed. It is measured in MHz. Most systems use 400MHz DDR memory. This would be the safe bet with almost any processor you may have. 400MHz has also become the most common to buy, there is not much slower than that left to buy.

Memory from a reputable manufacturer will ensure that you don't have problems with it and will also provide a certain amount of overclocking if you are into that. Even better would be to get faster memory, it just runs down at the computers speed, even if it is designed for more.

Another aspect of memory has come into play, being highlighted mostly by the enthusiastic overclocking crowd, and that's latency.

Memory is a bank or table of places where information can be stored. In order to get the specific rows and columns certain things have to be activated within the memory. In a nutshell latency refers to how long it takes to be able to acces another part of memory. The shorter the time it takes, the quicker it is.

Low latency memory comes at a huge price premium, with 512MB of top class memory costing more than some processors.

But does it actually benefit you?

If you are into high-speed 3D games then there could certainly be a difference. For the rest of us, there probably won't be much difference. It's still worth it however to keep latency in mind when shopping around. I would certainly choose a lower latency model when buying.

Dual channel memory is another recent addition to memory technology. What it does is it puts the memory into pairs, the two pairs together can increase on the performance and speed of the memory by up to 10%. The motherboard has to support it, and the memory has to be the dual channel kind. Dual channel will work even when not in a pair, but normal memory will have no advantage when put in a pair.

Finally, DDR2 is a newer addition available for Intel systems. It has 240 pins (the little copper strips at the end that plugs into the slot) as opposed to DDR memory's 184 pins. In this respect the two are completely incompatable. DDR2 is by design meant to be in pairs, they don't have to be, but they all have dual channel capability. Only Intel processors with LGA775 socket type use this memory, but it is much faster.

So, whenever looking for more memory, try to bear these factors in mind...

-Do you need DDR or DDR2 (LGA775 systems) -What speed do I need? Usually 400MHz (named PC3200) or faster? -256MB minimum, preferably 512 or up to 1GB -Dual channel pairs. Do you need them and does your computer support them? -Latency, lower the better, but not essential. CAS of 3 is normal.

A Guide to Computer Desks

Computer furniture has evolved over the years. Improvements in the design and decor of computer desks have revolutionized the way people work at the computer. With the increase in the number of computer accessories, such as keyboard, mouse, and additional attachments like the printer, scanner, hard disks, modems, the allotment of space for all these accessories has become a challenge. Modern office furniture has to be modular, movable and flexible.

The most important feature of a good computer desk is ergonomic design. As people work spend more hours at the computer, it is important that the desks are comfortable to sit at for long hours. Moreover, they have to look good and blend in well with the rest of the office or home. As greater comfort ensures greater productivity, companies are more willing to provide the best computer desks for employees.

Modular computers desks provide flexibility and versatility in use – they can be remodeled very easily depending on the use. These are ideal for the limited office spaces of today, and also work well in homes because they can be easily changed according to different requirements. Fittings are provided to accommodate various other accessories that may be required while using the computer, such as a document holder, wrist rest, file hangers, CD holders, or telephone shelf. Such desks are also often accompanied by a manual that contains comprehensive instructions for assembling or disassembling the unit. On the whole, computer desks today are leaner, and have fewer drawers and more shelf-space than before.

In most modern computer desks, the unique arrangement of the panel systems ensures optimum space, privacy and advanced wire management. The spine of the desk should be designed to not only provide power and data to the whole unit but also to support the desk assemblies, staking storage, divisional screens, transfer screens and other accessories. The end result is optimal space utilization.

A versatile computer desk should not necessarily compromise style. Computer desks are being designed with every kind of material possible ranging from traditional oak and wood to metal, glass and fiber.

5 Stress Reducing Computer Tips

For most entrepreneurs computers are an intrical part of our business. An entrepreneur can not afford for their computer to be inoperable even for a minute. Implement some of these quick and affordable computer tips to keep your computer healthy and making money for your business.

#1 - Double Internet Speed

Comcast recently doubled cable modem download speeds. Now you can surf the Internet and download files twice as fast. However, you need to power cycle your cable modem [unplug it for 30 seconds and reboot computer] for the new configuration to be automatically downloaded to your modem.

#2 - Connecting to Work from Home

Having trouble with your corporate VPN connection when working from home? Oftentimes this can be fixed with a simple firmware upgrade to your network router or a slight change in settings.

#3 - Sudden Lost Connection

Has your Internet connection suddenly stopped working? Frequently computer users with software-based firewalls suddenly find their Internet connection no longer available. Oftentimes when you download a software update, it can change your original configurations. As a quick test, disable the software firewall. If connectivity returns, it’s a misconfiguration issue.

#4 - Slow E-mail and Internet Browsing

Has your computer been working wonderfully, but suddenly e-mail or Internet browsing is painfully slow? It could be your cable connection went out. And although the connection has returned, your computer and the cable modem may be having difficulty communicating. Try power cycling your modem.

#5 - Eliminate Popups

Google offers a free popup blocker with its toolbar. Download the toolbar at www.toolbar.google.com. System requirements: Microsoft Windows 95/98/ME/NT/2000/XP, Microsoft Internet Explorer 5.0 or later. The popup blocker requires Internet Explorer 5.5 or later.

Computer Geeks and Garden Gnomes

First and foremost before I begin my ranting it is worth mentioning that there are many very helpful and considerate people out there in the cyber wilderness who devote much of their time to providing open source and free scripts of all variations from PHP, CGI and Java to name but a few. They provide dedicated support, do not insist on payment, and spend much of their free time helping you avoid having to part with your hard earned cash to get free programs and scripts up and running on your websites.

Now, that having been said I have just spent an enlightening couple of days installing several PHP and CGI scripts, mainly because whilst I have some experience of installations, the only true way to become fast and efficient with all this geeky stuff is to install, de install and test a variety of applications and programs yourself.

After two days and over a hundred scripts I am left drained. Half of the scripts I just dumped immediately due to poor or non-existent documentation and bad layout of files. It amazes me that some quite intricate scripts are left high and dry without any installation documents at all. In other words, the author spent days programming and putting together complicated scripts, to fail miserably on poor or non existent documentation. Aside from this, some sites you visit in order to download this material insist on blitzing you with numerous pop ups – the end result of which is neither good for the person visiting the website or the website owner. Both part very quickly. Perhaps I am intolerant but any sign of boxes leaping up in the air and blind adverts and I am gone. I know I am not alone.

Add to this the frustration of taking the time to read through endless documents and CGI scripts on websites only to find that when you click on a link for more information or a download you find it is dead, the site under maintenance or what was advertised as free is not actually free. Either that or you go to the extreme of getting a script working only to find the writers advertisement popping up all over the place to the extent it warrants dumping the script. Yes I know you can remove it for a fee but why didn’t you tell me that before I installed it?

Even quite clear documentation often omits what is to the writer an obvious requirement but not something that he or she chooses to share with their hapless user – classic example might be forgetting to mention that an SQL database is needed. Hardly a minor omission.

At the height of one frustrating and particularly badly written install attempt I imagined myself as John Cleese with a garden gnome under my arm hunting for the writer. Anonymity on the internet does has its advantages in this case.

Now, I know you will be cynical and say that most of this is down to the fact that many script writers are hoping you will pay them to install their scripts for you, indeed many do offer installation services. This really is a bad way of advertising your services. There are plenty of people who will have trouble with the easiest installs and if you wrote clear and concise documentation which any user can see is genuinely comprehensive, you are more likely to secure customers as a result of failed installs.

During this laborious exercise we went through scripts of all kinds some of which include; online photo albums, content management systems, member login and authentication scripts, virtual postcards, email programs, hosting scripts, live helper, communication, e commerce, shopping carts, quiz and chat programs to name but a few. We also purchased 3 scripts. Only one of those free scripts was simple to install and marginally better than the free versions available. Paying money does not necessarily mean better service. In fact one photo album provider charging around $30 dollars per script provided bad install information and less than helpful advice, immediately deleting anything that mentioned install problems from his forum.

It has been an experience. If none of this has meant anything to you and you have no idea about scripting or installing scripts then consider yourself fortunate and leave it to the geeks if you are able.

For those of you that regularly dive into scripting for your websites – here is a useful tip that saved us no end of time and frustration. The minute you come up against bad scripting, bad documentation or difficult to install scripts – trash them, ditch them and move on. There are plenty of others. Leave the tricky badly written stuff to the real hardcore freaks.

Computer Cleaning

PC Cleaning

Taking care of your computer will help it last longer and work better.

To clean your mouse - The trackball can pick up dirt and dust from your desk and mouse pad. Also, the wheels that the trackball come in contact with get dirty and need to be cleaned. If you notice your mouse "doesn't work right", it may be time to clean it. First, turn your PC off. Turn your mouse over and you will see the ball sticking out of a cover. Look at the arrows on the cover and turn it in the indicated direction to open it up. Don't worry about anything falling out. The only thing that comes out is the ball, and maybe a little dust, and you want to take that out anyway. You can clean the ball with alcohol if it needs it, but usually just wiping it off will work. A cotton swab dipped in rubbing alcohol works well for cleaning the wheels. When you're done, drop the ball back in and put the cover back on. If cleaning it doesn't help, it may be time to replace it. PC mice are usually less than $10 and are sometime free if you watch for sales in the Sunday paper.

To clean your optical mouse - If you have an optical mouse, one with a red light under it, there is no ball and you can just wipe off the lenses with a cotton swab.

To clean your keyboard - Never spray anything into your keyboard, this includes coffee. You can use a vacuum cleaner to clean dust, dirt, staples and cookie crumbs from your keyboard, but make sure your computer is off before starting, and make sure you don't have any loose keys. Rubbing alcohol works well to clean the keys and surface of your keyboard, but use it sparingly. Using a cloth works well, as paper towels tend to leave little pieces behind. If you spill something sticky like your favorite soft drink on the keyboard, the keys will likely start to get sticky as it dries. It could be time to replace it. They too are cheap and can be free if you watch for a sale.

To clean the computer - You can use a vacuum to clean around the vents and anywhere else that looks dusty. Be careful in the back of the PC to not knock any plugs loose. It is a good idea to keep the vents clean and free of dust, pet hair or lint. How often you clean your computer depends more on the environment it's in than the manufacturer's recommendation. I have 2 dogs that shed so I clean my computer about every 2 months. A cloth and alcohol can be used on the outside of the PC if it's dirty but, again, turn it off first.

To clean your monitor - A vacuum can be used to remove dust from the vents. If you have fingerprints on the glass, you can use the same wipes that you would use on your glasses or use as soft cloth and warm water followed by a dry cloth. Think of your monitor glass the same way you think of glasses, if you wear them. They may have delicate coatings on them that can be scratched. Always avoid chemicals on displays. To clean a laptop display or LCD - These displays are plastic and can also be scratched by paper products such as tissues or paper towels or damaged by chemicals. Use a cloth made for glasses or camera lenses or a soft cloth and warm water followed by a dry cloth.

Five Simple Steps to Speed up Your Computer

Most people download and save so much information on their computer that before long the computer starts slowing down and the user has no idea what the problem is. However, even if you are not a computer whiz there are several things you can easily do to speed up your computer quickly and easily.

Tip #1 Defrag

One of the first things you should do if you want to speed up your computer is to defrag. This is something you can easily do and a wizard on your computer will help you defrag. You might want to do it overnight, however, because it can take a long time.

Tip #2 Spyware Remover

Download a good spyware remover. Most computers have a lot of spyware running in the background, stealing information and slowing down your computer. Remove it frequently if possible.

Tip #3 Empty Temp Internet Files

Most Internet browsers save your last visited web pages for up to 30 days. If you don't want all of those pages saved then change the days to one or two, or none, whatever meets your needs.

Tip #4 Turn off Active Desktop

When you turn of active desktop that will be one less thing using memory on your computer. Plus, you won't really notice the difference.

Tip #5 Antivirus Programs

Make sure you have a good anti-virus program and use it frequently. If you are deleting virus and preventing them from feeding on your computer then you will have a faster computer as well.

Once you perform these simple tasks you will be amazed at how much faster your computer runs and with so little effort.

Coping with a Serious Data Loss from your Computer Hard Drive

Data loss is an expensive reality. It's a hard fact that it happens more often then users like to admit. A recent study by the accounting firm McGladrey and Pullen estimates that one out of every 500 data centers will experience a severe computer disaster this year. As a result, almost half of those companies will go out of business. At the very least, a data loss disaster can mean lost income and missed business opportunities.

The other side of data loss is the psychological and emotional turmoil it can cause to IT managers and business owners. Despair, panic, and the knowledge that the whole organization might be at risk are involved. In a sense, that's only fair, since human error is one of the two largest contributing factors in data loss. Together with mechanical failure, it accounts for almost 75 per cent of all incidents. (Software corruption, computer viruses and physical disasters such as fire and water damage make up the rest.)

Disk drives today are typically reliable. Human beings, it turns out, are not. A Strategic Research Corp. study done in 2000 found that approximately 15 per cent of all unplanned downtime occurred due to human error. A significant proportion of that happened because users failed to implement adequate backup procedures, either having trouble with their backups, or having no backup at all.

How does it happen that skilled, high-level users put their systems - and their businesses - at such risk?

In many cases, the problem starts long before the precipitating system error is made, that is, when users place their faith in out-of-box solutions that may not, in fact, fit their organization's needs. Instead of assessing their business and technology requirements, then going to an appropriate engineered solution, even experienced IT professionals at large corporations will often simply buy what they're sold. In this case, faith in technology can be an vice instead of a virtue.

But human intervention itself can sometimes be the straw that breaks the technology's back. When the office of a Venezuelan civil engineering firm was devastated by floods, its owners sent 17 soaked, mud-coated disks from three RAID arrays to us in plastic bags. A tough enough salvage job was made even more complex by the fact that someone had frozen the drives before shipping them. As the disks thawed, yet more damage was done. (After eight weeks of painstaking directory-by-directory recovery, all the data from the remaining fifteen disks was retrieved.)

Sometimes, the underlying cause of a data loss event is simply shoddy housekeeping. The more arduous the required backup routine, the less likely it will be done on a regular basis. A state ambulance monitoring system suffered a serious disk failure, only to discover that its automated backup hadn't run for fourteen months. A tape had jammed in the drive, but no-one had noticed.

When disaster strikes, the normal human reaction is panic. Because the loss of data signifies critical consequences, even the most competent IT staff can jump to conclusions, and take inappropriate action. A blank screen at a critical time can lead to a series of naive decisions, each one compounding the preceding error. Wrong buttons get pushed, and the disaster only gets worse. Sometimes the pressure to correct the system failure speedily can result in an attempt to reconfigure an entire RAID array. IT specialists are typically not equipped to deal with crisis modes or data recovery techniques. Just as a good physician is trained to prolong life, the skilled IT specialist is trained to keep the system running. When a patient dies, the physician turns to others, such as nurses or counselors to manage the situation. When significant data loss occurs, the IT specialist turns to the data recovery professional.

Data recovery specialists are innovative problem solvers. Often, the application of basic common sense, when no-one else is in any condition to apply it, is the beginning of the journey towards data recovery. The data recovery specialist draws on a wealth of experience, married to a "never say die" attitude, and a comprehensive tool kit of problem-solving procedures. Successful recovery outcomes hinge on a combination of innovative logistics, applied problem-solving, and "technology triage," the process of stabilizing an affected system quickly, analyzing and treating its wounds, and preparing it for surgery. The triage process sets priorities, such as targeting which files are needed first or which are absolutely vital to the functioning of the business, and establishes whether files might be recovered in less structured formats (such as text-only), which may be desirable when time is crucial.

The art and science of professional data recovery can spell the difference between a business' success or its failure. Before that level of intervention is required, though, users can take steps to ensure that the probability of a data loss disaster is minimized.

Basic to any business technology plan is a regular fire-drill procedure. Back-up routines may be in place, staff may assigned to specific roles, hardware and software may be configured - but, if the user isn't completely sure that everything works the way it should, a data loss event is inevitable. Having adequate, tested, and current backups in place is critical. A hardware breakdown should not be compounded by human error - if the malfunctioning drive is critical, the task of dealing with it should go to a data recovery professional.

Just as data loss disasters are rooted in a combination of mechanical failure and human error, so, too, the data recovery solution lies in a creative marriage of the technological and the human. The underlying philosophy of successful data recovery is that technology is something to be used by human beings, not something that uses us.

10 Easy Steps to Speed Up Your Computer - Without Upgrading

10 Easy Steps to Speed Up Your Computer - Without UpgradingBy Jim ShutesLapeer Tech GroupIt seems that the longer you own your computer, the slower it gets! A lot of people will keep their computer until it gets so slow that they feel they need a newer, faster model. Some feel like the reason it is getting slower is because it is getting older, when that is just not the case. Your computer should run just as fast as the day you brought it home – if you follow these 10 Easy Steps to Speed Up Your Computer.1. Empty the Temp directory regularly. After a short while, the temp directory fills up with hundreds of temp files that always get scanned over when Windows starts up and when programs launch. This slows everything down immensely.Rule of thumb for Temp Files: If you don’t have any programs open (and nothing minimized in the bar below), then you shouldn’t have ANY temp files in your temp directory. If you do, delete them.To delete Temp files, make sure NO programs are open, and…a. In Windows 95, 98 or Me, go to C:WindowsTemp and delete everything inside the Temp folder.b. In Windows 2000 or XP, it is a little trickier. First, make sure that you can see hidden folders. Double-click My Computer. Click on the Tools pull-down menu, and then on Folder Options. Click on the View tab. Scroll down and click on Show Hidden Files and Folders. Click Ok. Now you can go to the C:Documents and SettingsAdministratorLocal SettingsTemp folder. Delete everything here.2. Empty the Temporary Internet Files regularly. To empty Temporary Internet Files, go to your Control Panel and double-click the Internet Options icon. Choose to Delete Cookies, and to Delete Files. This will clear all of your Temporary Internet Files.3. Check your hard disks for problems.a. For Windows 95, 98, or Me, double-click My Computer. Right-click the C-drive and click on Properties. Click on the Tools tab and choose to check the computer for problems. If you choose to do a Thorough Scan, this will do the hardware check for physical disk damage or sector damage. Choose to fix any errors it finds.b. For Windows 2000 and XP, double-click My Computer. Right-click the C-drive and click Properties. Click on the Tools tab and choose to check the computer for problems. Click on Check Now. You will then have two check boxes. The top option is for the file check, and the second option is for the hardware (physical disk) check. Check either one, or both. At least check the top one. Hit ok, and reboot. This may take some time, but let it run.4. An even more thorough disk check, would be to use a 3rd party utility. One of my favorites is TuneUp Utilities 2004. It does cost $39.99, but they do offer a FREE download trial of 15 days. This program does a really good job of fixing software and physical hard drive problems. It also tunes up your system for increased speed, and streamlines your operating system for peak performance. Download it HERE... http://www.lapeertechgroup.com/downloads.asp5. Or, you can do a few of the performance tweaks yourself, if you have Windows XP. By default, EVERYTHING is turned on in Windows XP. It isn’t very streamlined for performance, but rather for appearance. You can turn off a few of the unnecessary features, and Windows will still work just fine, and maybe a little faster.To do this, right-click on My Computer and click on Properties. Click on the Advanced tab. Under the Performance section, click on the Settings button. On the Visual Effects tab, you will see a list of check boxes. By default, these are all on. You really don’t need any of them for Windows to run. Go through the check boxes one by one, and determine which ones you can and can’t live without.6. Turn off Active Desktop. Active Desktop turns your desktop into a web page, and allows you to have things like a real-time calendar, and up-to-the-minute weather or stocks. These are nice, but really slow down your computer. And even if you don’t use Active Desktop for anything, just having it active can cause a performance decrease. Turn it off.a. In Windows 95, 98 and Me, right-click on the desktop and in the pop-up menu, choose Active Desktop. Inside that option, uncheck Active Desktop. If there is no check next to it, then it isn’t on. Don’t choose it. Instead, just click the desktop again to get out of the menu.b. In Windows 2000, right-click on the desktop and in the pop-up menu, choose Active Desktop. Inside that option, uncheck Show Web Content. Again, if there is no check next to it, then it is not on. Do not check it.c. In Windows XP, right-click on the desktop and in the pop-up menu, choose Properties. On the Desktop tab, choose Customize Desktop. Now, on the Web tab, make sure that there are no websites chosen here. If there aren’t any, then Active Desktop is not on. Cancel and go back to the desktop.7. Install and run a good AntiVirus program to keep out viruses that can take over your system. One of my favorites is AVG. It is not only a really good AntiVirus program, but it is also FREE! If you don’t have any AntiVirus software on your computer, get AVG AntiVirus NOW by downloading HERE... http://www.lapeertechgroup.com/downloads.asp8. Get rid of Spyware. A lot of computer users have Spyware and don’t even know they have it, much less how to get rid of it. If your computer has been taking you to websites that you don’t want to go to, or if you get pop-ups when you aren’t even on the Internet, or if your computer has been running extremely slowly lately, for no reason, you probably have Spyware.On all of the computers that I setup, I install two different AntiSpyware programs: AdAware SE and SpyBot. These two programs are highly recommended by TechTV (G4) and other computer authorities (including my own research on Spyware) and work very well together. They compliment each other and catch Spyware that the other misses, but together, do a very good job.Get SpyBot HERE... http://www.lapeertechgroup.com/downloads.asp. Download all updates and run the Immunize option a couple of times.AdAware SE does a good job when you keep up on the updates and manually scan your system with AdAware. Get it HERE... http://www.lapeertechgroup.com/downloads.aspIn some cases, when the Spyware has become too entwined into your system, even a computer repair technician can’t get rid of the Spyware. At this point, it is better to just backup only what you need and have the operating system reinstalled. Believe me, when your computer gets to this point, you don’t want to just put a “band-aid” on it. Just start from scratch with a clean system. It’s the best way to go.9. Streamline MSCONFIG. One thing that really causes a HUGE performance decrease is to have unnecessary programs running in the background. Some of these programs can be seen in your System Tray (located next to the clock). These are tiny programs that are robbing you of memory and processing power. Some of them you need, while most you don’t. Some of the programs you DON’T need are printer icons, CD burning icons, shortcuts to programs (such as video settings), AOL, any Instant Messaging Programs, etc. Just because these programs aren’t always running, doesn’t mean that you still can’t print, burn CDs or Instant Message. They can all be run from a shortcut.You can use a utility, called MSCONFIG, to turn OFF unnecessary Start Up items.a. In Windows 98, Me, and XP, click on StartRun and type msconfig. Click on the Startup tab. This is a list of everything that is running in the background, some of which show up in the System Tray. Now, be careful, some of these you do need. Some items to keep are Ctfmon.exe (XP), Scan Registry (Win98, Me), Task Monitor (Win98, Me), System Tray (Win98, Me), LoadPowerProfile (Win98, Me), Rundll.32, any AntiVirus programs (such as McAfee, Norton, or AVG). Others, you can uncheck, such as NeroCheck, ypager, qttask, AOL, and any other Instant Messaging programs, or printing programs. Remember, if something doesn’t work, because you turned it off, it can always be turned back on. You just have to reboot every time you make a change here. But, as you uncheck the unnecessary programs that run in the background, you will see that Windows loads much faster, that there are less icons in the System Tray, and that your system is much more “snappy” and quick to respond.b. In Windows 2000, MSCONFIG wasn’t supplied. You actually have to download and run an MSCONFIG utility.

Types of computer infections

Computer Infections can be broken up into 4 main categories which are explained in detail below:VirusesComputer Viruses are small pieces of software that attach themselves to real programs. An example would be a virus that attaches itself onto windows explorer. Each time you run the program windows explorer the virus will also be executed and perform the function that it was meant to perform. This can be several things such as damaging files on your computer, or erasing them all together. This is also the time in which the virus will try to spread itself onto other programs and even other computers!Worms - A worm just like a virus is a small piece of software. However worms rather then relying on an external program to function, will run themselves over computer networks and security holes to spread. The worm will scan the network from it’s host computer until it finds another computer that it can attach itself to. It will then continue this process to replicate. Because this type of infection runs by itself it can have devastating impacts. The Mydoom worm is estimated to have infected over a quarter million computers in a single day when it first launched back in March 1999.Trojan HorsesA Trojan horse is a computer programs that claims to be one thing, but is actually another. For example you might receive a Trojan horse that is disguised as an image, but when you go to open the file, it will do whatever it is that it was written to do.E-mail VirusesEmail Viruses are very common. They work by spreading themselves through email messages. Once they infect a computer, they will then go ahead and replicate themselves by automatically mailing out again to everyone in the victim’s e-mail address book. Several of these virus’s have raced through the internet. Examples of email virus’s are the Melissa Virus, and the ILOVEYOU virus.--Feel free to reprint this article as long as you keep the following caption and author biography in tact with all hyperlinks.
