Trojan Horses are also nightmares too. Here we'll inform you about Trojan Horses.

A Trojan Horse is a malicious security-breaking program that appears to be a benign and legitimate program, but it is designed to have destructive effects on a computer and may open a backdoor. Unlike a virus, a Trojan Horse does not replicate itself. One example is a free game that someone could download, but it actually is a Trojan Horse that holds viruses and worms that invade your computer.

The origional story of the Trojan Horse happened like this: the Greeks built a huge wooden horse that a certain force of men hid in. The Greeks pretended to sail away from Troy after a ten-year seige, and the Trojans pulled the wooden horse into their city as a victory trophy. Later that night, the Greek force crept out of the wooden horse and opened the gates of the city for the rest of the Greek armyto enter, which had secretly sailed back to Troy. The Greek army entered and destroyed the city and ended the war.

The term "Trojan Horse" refers to a trick that causes a target to lower their guard and allow an enemy into a securely protected place like the Trojan Horse program found on the Internet.
