This is my cousins gateway pc...2gig, 256mb, winxp home.
I cleaned off 254 virus infected files using avg and about 75 spyware programs using spysweeper and spybot. Both programs act like it did got rid of cws_ns3 successully, but as soon as it is deleted, it comes right back. I have read several things online that talk about editing the registry and deleting several keys, which I have done. I've tried cwsshredder program, which doesn't even detect it at all. I've tried ad-aware. I've tried running the programs in safe mode, with no luck. I even tried using hijackthis, and haven't had success with that. I believe there were a few other small things, but I can't remember the programs.
