Bearshare is riddled with spyware and adware - install this if you want to run any p2p filesharing stuff:

http://www.microsoft.com/antispyware

... which warned me about Bearshare - MS Antispyware doesn't even blink when Limewire is running.

Limewire slows PCs down because (I think) it's based on Java, or at least it was - not much you can do about that, but your PC will probably run slower when you're downloading a LOT of different files simply due to the large amount of files the program will have open.

Any other good P2P programs out there? I can't find half the Fabric compilations I'm looking for!!
