Well i only use p2p for music, so im fine with winmx, i don't download games becuase there easy to virus (you can tell if a music file has a virus by its size on winmx), also my mate (against my advise) downloaded norton 2002 pro from there and it was virused beyond reconition (like i said it would).
Kazza just puts spyware on you and so does DC++.
Winmx doesn't anless your stupid enough to download it.
But i have never used Limewire, i take it is is good?
