A
Trojan or Trojan Horse
A Trojan or Trojan Horse is a program that appears
legitimate, but performs some malicious and illicit activity when it is run.
It may be used as a hacker tool to leak a user's password information or it
may simply destroy programs or data on the hard disk. Contrary to a virus, a
Trojan does not replicate itself. It stays in the computer doing its damage
or allowing somebody from a remote site to take control of the computer.
Trojans often sneak in by attaching to a free game or other utility. |
