A Trojan Virus is a type of Malware that enters your PC and damages other files. The concept of Trojan is taken from the battle of Troy (aka the Trojan War).

A Summary of the Trojan War:

In the year 1200 BC, the city of Troy and the Greeks were having a war. The walls of Troy were like our computer’s security system, which was difficult to break. Therefore, the Greeks constructed a huge wooden horse and gifted Troy as a token of victory. The people of Troy trusted the greeks and brought the Trojan Horse inside the city, bypassing the city defenses. When the people of Troy were celebrating their victory, the Greeks broke out from the wooden horse and started attacking the people of Troy by surprise. They even opened the gates of Troy to let other Greeks in. The city of Troy was completely destroyed from the inside within a few hours.

Similar to Trojan War, Hackers create fake applications so that the user installs them on the PC. After that, the software hacks the PC and provides access to the hackers.
