Computer Virus Info

What is a computer virus: A computer virus is a set of program instructions that attaches itself to a file, reproduces itself, and spreads to other files. You might encounter several types of viruses.

A virus that attaches itself to an application program, such as a game utility, is known as a file virus.

A boot sector virus infects the system files your computer uses every time you turn it on. 

A macro virus infects a set of instructions that automates document and worksheet production.

Viruses can slip into your computer from a variety of sources, such as floppy disks, homemade CDs, and Web sites that contain games and other supposedly fun stuff. E-mail attachments are another common source of viruses. HTML-formatted e-mail is susceptible to viruses and worms hidden in program-like "scripts" that are embedded in HTML tags.
