Trojan Horse (malware)

A Trojan Horse in computer terms is a kind of malware which masquerades as one harmless thing but once accepted onto a clean system will deploy malicious software. The name comes from the original Trojan Horse, in which solders hid until the horse was brought into the city. In the same way, Trojan malware must be brought in by either a person or another piece of software. However, more complex pieces of malware will sometimes show traits of several classifications. In such cases, it may act like a worm and infiltrate a system, then act as a Trojan Horse to hide on the infected computer.[1][2]
