I feel slightly stupid for having to ask this: What does PeerGuardian do? I gather that it keeps the copyright authorities at bay. I'm having trouble making sense of it beyond that. Does it address other P2P security issues? Admittedly, I have not installed it. Would like somewhat of an idea before I do so. Also, I don't use p2p very often anymore, but I'd like to keep PeerGuardian in mind if I do.
