as for kazaa, I was refering to everyone as a whole. it is just a bad scene.
I'm not sure what to think about previx, I hear good things and I hear bad things, some of the bad things I heard was that previx actually creates some of this spyware in order to get you to buy their product. And I don't mean like people say symantec(norton) creates viruses, I mean some of the pop-ups actually take you to the previx homepage. I havn't seen this for certain and I am just repeating gossip but since process explorer can isolate and kill a process and free a file handle, it is just more manual, I really don't need much in the way of anti-spyware.
