Description


23. What is a trojan/worm/virus/logic bomb?

This FAQ answer was written by Theora:

Trojan:
     Remember the Trojan Horse? Bad guys hid inside it until they could get
     into the city to do their evil deed. A trojan computer program is
     similar. It is a program which does an unauthorized function, hidden
     inside an authorized program. It does something other than what it
     claims to do, usually something malicious (although not necessarily!),
     and it is intended by the author to do whatever it does. If it's not
     intentional, its called a 'bug' or, in some cases, a feature :) Some
     virus scanning programs detect some trojans. Some virus scanning
     programs don't detect any trojans. No virus scanners detect all
     trojans.
Virus:
     A virus is an independent program which reproduces itself. It may
     attach to other programs, it may create copies of itself (as in
     companion viruses). It may damage or corrupt data, change data, or
     degrade the performance of your system by utilizing resources such as
     memory or disk space. Some virus scanners detect some viruses. No
     virus scanners detect all viruses. No virus scanner can protect
     against "any and all viruses, known and unknown, now and forevermore".
Worm:
     Made famous by Robert Morris, Jr. , worms are programs which reproduce
     by copying themselves over and over, system to system, using up
     resources and sometimes slowing down the systems. They are self
     contained and use the networks to spread, in much the same way viruses
     use files to spread. Some people say the solution to viruses and worms
     is to just not have any files or networks. They are probably correct.
     We would include computers.
Logic Bomb:
     Code which will trigger a particular form of 'attack' when a
     designated condition is met. For instance, a logic bomb could delete
     all files on Dec. 5th. Unlike a virus, a logic bomb does not make
     copies of itself.
