I went through the steps explained here: http://www.techspot.com/vb/topic58138.html but I still seem to be infected. Peer Guardian is picking up the fact that my computer is trying to contact 188.8.131.52, an IP address associated with Trojan infested computers. AVG Antirootkit scan turned up nothing. Combofix, HJT, AVG Anti-Spyware logs attached. Thank you for your help.
