Some computer users, called hackers, try to sabotage other people's computers, and thus create
software that can manipulate or destroy another computer's programs or data. One such program,
called a logic bomb, consists of a set of instructions entered into a computer's software. When
activated, it takes control of the computer's programs. A virus attaches itself to a program, often
in the computer's operating system, and then copies itself onto other programs with which it
comes into contact. Viruses can spread from one computer to another by way of exchanged disks
or programs sent through telephone lines.
