• Computer virus -- a software time bomb that may destroy computer files unless eradicated with a virus checker. Often spread by pirated software or from computer files downloaded from a bulletin board.

• Trojan horse -- a logic bomb hidden in a legitimate program that may be doing harm during normal operation of the host software.

• Worm -- a program that reproduces itself and worms its way into alien operating systems.

• Software piracy -- unauthorized copying of copyrighted software, a common kind of white-collar computer theft.
