What is a Trojan Horse?

A Trojan Horse is a program that is disguised as useful software that is available for free download. The name Trojan Horse is derived from the mythical Trojan Horse that was used in ancient Greece to gain a backdoor entry into the enemy’s camp.

Many people download and install such Trojan Horse programs and later find that their personal data has been compromised.

As soon as a Trojan Horse is executed on a computer, its developer gets control over the victim’s computer. From there on, it all depends on what the attacker wishes to do. He may steal your personal information or spread a virus on your computer or do nothing at all.
