viruses
A commonly used term for any kind of malware.
Originally, by analogy with biological viruses, via science fiction,
"virus"
meant software that "infects" other programs by embedding a copy of
itself in
them, so that they become Trojan horses. Executing an infected
program would run
the virus too, allowing it to propagate, normally without the user's
knowledge.
A virus has an "engine" - code that enables it to propagate - and may
also have a "payload"
- what it does apart from propagating. It needs a "host" the
particular hardware and
software environment on which it can run and a "trigger" - the event
that starts it running.
Unlike a worm, a virus cannot infect other computers without
assistance.
It is propagated by vectors such as users downloading infected
software.
Viruses written by particularly antisocial crackers may do
damage, like deleting files or encrypting them for ransomware.
By the 1990s, viruses had become a serious problem, especially among
Windows
users. The production of special antivirus software became an
industry
in itself, until it finally became a default part of the operating
system.
See boot virus, phage. Compare back door. See also {Unix
conspiracy}.
