Trojan

A trojan is malware that appears to perform a function for the user prior to run or install, but instead gets fake access of the user's computer system. "It is a harmful piece of software that looks real. Users are typically tricked into loading and putting it on their computer", as Cisco describes. The term is derived from the trojan horse story in Greek mythology.

Antivirus software is designed to detect and delete Trojan horses and prevent them from ever being installed. In situations where the security of the computer system is important, you should to erase all data from the hard disk and reinstall the operating system and required software.
