A computer virus is a small piece of software that attaches itself to other programs and runs when those programs run, allowing it to reproduce by attaching to other programs or cause damage. Viruses can damage or destroy data files, make disks unreadable, and potentially cause unintended harm to systems. They piggyback on real programs to spread and affect computers without the user's knowledge or consent.

2. WHAT IS A COMPUTER VIRUS?
A virus is a small piece of software that
piggybacks on real programs. For
example, a virus might attach itself to a
program such as a spreadsheet program.
Each time the spreadsheet program runs,
the virus runs, too, and it has the chance
to reproduce (by attaching to other
programs) or wreak havoc.
