Trojan Guarder initiates a system named Guard Ghost to supervise all running processes in the memory system, Windows files, and open ports to search for worms and Trojan horses at any time. Once a Trojan or worm appears, even if it hides in other programs, Trojan Guarder will display a signal for warning and eliminate it consequently. Meanwhile, Trojan Guarder will clear all Trojan system-linked files as well as relative registered files.

Version 5.12 may include unspecified updates, enhancements, or bug fixes.
