[quote name='Nirvanaguy777']For my kazaa program, need something to kill off some or all the spy/adware it leaves me.[/quote]
Like WSB said, Ad-Aware and SpyBot are great programs. SpyHunter is good too, so I hear.
I'm not really a fan of of P2P (cough), but Shareaza is good because it fuses Bit-Torrent, Gnutella, E-Donkey, and its own Shareaza network together into one program.
