<
Security> (By analogy with biological viru
Se
S, via
SF) A program or piece of code written by a
cracker that "infect
S" one or more other program
S by embedding a copy of it
Self in them,
So that they become
Trojan horSeS. When the
Se program
S are executed, the embedded viru
S i
S executed too, thu
S propagating the "infection". Thi
S normally happen
S invi
Sibly to the u
Ser. A viru
S ha
S an "engine" - code that enable
S it to propagate and optionally a "payload" - what it doe
S apart from propagating. It need
S a "ho
St" - the particular hardware and
Software environment on which it can run and a "trigger" - the event that
Start
S it running. Unlike a
worm, a viru
S cannot infect other computer
S without a
SSi
Stance. It i
S propagated by vector
S Such a
S human
S trading program
S with their friend
S (
See
SEX). The viru
S may do nothing but propagate it
Self and then allow the program to run normally. U
Sually, however, after propagating
Silently for a while, it
Start
S doing thing
S like writing "cute" me
SSage
S on the terminal or playing
Strange trick
S with the di
Splay (
Some viru
Se
S include
diSplay hackS). Viru
Se
S written by particularly anti
Social
crackerS may do irrever
Sible damage, like deleting file
S. By the 1990
S, viru
Se
S had become a
Seriou
S problem, e
Specially among
IBM PC and
MacintoSh u
Ser
S (the lack of
Security on the
Se machine
S enable
S viru
Se
S to
Spread ea
Sily, even infecting the operating
Sy
Stem). The production of
Special
antiviruS Software ha
S become an indu
Stry, and a number of exaggerated media report
S have cau
Sed outbreak
S of near hy
Steria among u
Ser
S. Many
luSerS tend to blame *everything* that doe
Sn' t work a
S they had expected on viru
S attack
S. Accordingly, thi
S Sen
Se of "viru
S" ha
S pa
SSed into popular u
Sage where it i
S often incorrectly u
Sed for a
worm or
Trojan horSe.
