Trojan.VirtualRoot

Trojan.VirtualRoot is a Trojan horse program that is dropped by the CodeRed II and CodeRed.F worms. The Trojan allows a hacker to have full remote access to the Web server that is infected by CodeRed II or CodeRed.F. Norton AntiVirus can detect an infection of CodeRed II or CodeRed.F on a Web server by detecting the payload (Trojan component) of this worm as Trojan.VirtualRoot.
