Further, on PeerGuardian2: It starts the Windows server service on your computer (which I discovered because a hidden catalog.wci (that's a Windows server indexing service database file - apparently) suddenly appeared in the System Volume Information folder and made my regular drive ghosting task fail, otherwise I wouldn't have known). Now a program that's supposed to be protecting my computer is turning it into a server? What's going on here? Anyone got any suggestions?

Is this PeerGuardian on the level or what?

On the plus side, it is brilliant at blocking outgoing IP calls, from whatever apps you have on your system. It has already blocked outgoing IP calls from two trojans that I had no idea were 'contacting home' from my computer. One is actually a pirated screen capture tool (HyperSxxp). Yeah, some applications downloads on P2P are high-class trojans that are very difficult to spot.
