| A program
that is loaded onto your computer without
your knowledge and runs against your
wishes. Viruses can replicate themselves. 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. An even more
dangerous type of virus is one capable of transmitting itself
across networks and bypassing security systems.
Some people distinguish between general viruses and worms.
A worm is a special type of virus that can replicate itself and
use memory, but cannot attach itself to other programs.
