The Trojan Horse is a big wooden horse from the Trojan War in Greek mythology. In the Trojan War, the Greeks were fighting against the city of Troy.
The Greeks could not enter the city or win the war. Because of this, Odysseus, one of the Greeks, thought of a way to trick them. The Greeks built a large wooden horse and left it outside the gates of the city as a present for the Trojans. The Trojans took the horse and put it inside their city, thinking it was a victory gift from the Greeks. Odysseus chose a horse so that Poseidon (God of the sea and creator of horses) would ensure them a save trip back to Greece. After the Trojan victory parties ended, the Greeks, who were hiding inside the horse, came out of it. They opened the city gates to let the other Greeks enter Troy. The Greeks easily overpowered the Trojans and took control of the city. Because of the Trojan Horse, the Greeks won the Trojan War.
Today the word "Trojan horse" is used for things that are similar to that story: something that looks good and okay, but in truth has another purpose, usually bad. An example for this is the computer virus "Trojan horse". -

A trojan horse (Sometimes called a trojan) is a special computer program. Trojan horses are programs that pretend to do a certain thing, but in reality they do something else. In some cases the user notices, in other cases they do not. Spyware programs are current examples of programs that work in that way.
It was named after the Trojan Horse in Greek mythology.
