Trojan Dropper - installs new software on the computer. Trojan Proxy - turns the computer into a proxy server providing anonymous access to the internet for the Trojan writer. Trojan PSW - password stealer, hunts the computer for stored usernames and passwords and forwards these to the Trojan writer. Trojan Spy - any form of spyware application, such as keyloggers, password stealers etc. Trojans get their name from the classical Greek story of the Trojan horse, used in the Trojan war. The Trojan horse was a large wooden horse left as a gift from the Greeks to the Trojans, the Greeks then sailed away (apparently admitting defeat). The Trojans moved the horse inside their city walls and then celebrated their apparent victory. Unfortunately for the Trojans the Trojan Horse contains a number of Greek soldiers who then killed the guards and let the remainder of the Greek army into the city who then sacked Troy. A Trojan is also known as a Trojan horse.
