any p2p breeds a lot of spyware on the system. if u r involved in 'p2p' u hav 2 accept this fact.
i may sound repeating somebody else, but spywareblaster/spywareguard r great tools. the definations 4 spyduard, may look old but they r still valid as they r generic. along with adaware/spybot, also use ms antispyware. if u wanna stl play safer, use prevx anti-intrusion system or zonealarm.
and no, adaware definately does not itself have spyware. there r similar sounding programs like no-adware, etc, which may perhaps have them !
