| virus (By analogy with biological viruses, via SF) A program that searches out other programs and "infects" them by embedding a copy of itself in them, so that they become s. When these programs are executed, the embedded virus is executed too, thus propagating the "infection". This normally happens invisibly to the user. Unlike a , a virus cannot infect other computers without assistance. It is propagated by vectors such as humans trading programs with their friends (see ). The virus may do nothing but propagate itself and then allow the program to run normally. Usually, however, after propagating silently for a while, it starts doing things like writing "cute" messages on the terminal or playing strange tricks with the display (some viruses include s). Many nasty viruses, written by particularly antisocial s, do irreversible damage, like deleting all the user's files. In the 1990s, viruses have become a serious problem, especially among and users (the lack of security on these machines enables viruses to spread easily, even infecting the operating system). The production of special has become an industry, and a number of exaggerated media reports have caused outbreaks of near hysteria among users; many tend to blame *everything* that doesn't work as they had expected on virus attacks. Accordingly, this sense of "virus" has passed into popular usage (where it is often incorrectly used to denote a or even a ). See , . Compare . See also . [] (1995-01-31) |
