Today's Pic (Fights) CLICK to enlarge BACK to return (Dimple Chad)	Today's Word RESET BUTTON A button or switch on most computers that allows you to reset the computer. When you press the reset button, the computer will enter its start-up procedure as if you had turned the power off and then on again. Generally, you would use the reset button only when a program error has caused your computer to "hang" (totally freezing up on you).

The word virus is inherently scary. Since the Michelangelo virus was first reported in 1991, computer viruses have been a hot topic.

But don't be frightened. Here's what a virus can and can't do and how to avoid them.

A virus is a bit of computer code that is capable of replicating and spreading to new files and computers. Although many viruses can immediately begin damaging computer files, they certainly don't need to have this quality to be defined as a virus. Many typically wait until certain conditions are met. For example, the original Michelangelo virus looked for the date March 6 before it became malicious.

Most virus writers want their viruses to spread to as many computers as possible. If a virus crippled the newly infected computer immediately, it could never spread very far, and ultimately the potential for widespread damage would be very much reduced.

The best way to protect yourself from computer viruses is to update your antivirus software and avoid opening attachments. Run an antivirus program that utilizes "on-access" scanning, such as Norton AntiVirus. This type of scanning occurs constantly in the background. Every time you copy a file to the hard drive, run a program, open a document or open an email, the files are automatically checked to see if they contain a virus. You're only notified if the program finds something suspicious.

A tip to the wise: Be especially careful with programs (i.e., files that end with a ".exe" extension) that you download from the Internet or exchange with others. This is an easy way to spread viruses. Only open an attachment if you expected to receive it and need to use it.
