The term Trojan is synonymous with malware that adds a backdoor, even if a bunch of old people think it's still okay to call other malicious code by this name. From: http://en.wikipedia.org/wiki/Trojan_horse_%28computing%29 In practice, Trojan Horses in the wild do contain spying functions (such as a Packet sniffer) or backdoor functions that allow a computer, unbeknownst to the owner, to be remotely controlled remotely from the network, creating a "zombie_computer". Because Trojan horses often have these harmful functions, there often arises the misunderstanding that such functions define a Trojan Horse.
