Computer Virus
A computer virus is a program that invades your computer
system, hides there, and makes copies of itself. Viruses
spread when you launch an infected application or start
up your computer from a disk that has infected system
files.
All computer viruses are manmade. A simple virus that
can make a copy of itself over and over again is relatively
easy to produce. Even such a simple virus is dangerous
because it will quickly use all available memory and
bring the system to a halt |
