Trojan
A type of malware
In computing, a Trojan horse is any malware that misleads users of its true intent by disguising itself as a real program. The term is derived from the ancient Greek story of the deceptive Trojan Horse that led to the fall of the city of Troy.
Generally speaking, a Trojan comes attached to what looks like a legitimate program, however, it is actually a fake version of the app, loaded up with malware.
