I have to stick my nose in here, sorry. I disagree with some of the above. You should never run CWShredder as a simple matter of course. It's designed for a specific infection. In some cases, running CWShredder can make a CWS infection even harder to diagnose. It forces it to mutate. Instead, consult with someone who knows what they are doing or do some research and find out what the experts in the field are recommending. Google is your friend.

Also, Spyware Blaster is great for preventing infection but it does nothing to clean up after you have been infected. It's nice to recommend that people install it, but it's not going to help resolve their current problem.

Lastly, telling someone to turn off their System Restore before they have fixed the problem is, IMO, a very bad practice. They have nothing to turn back to if they hose their pc by "fixing" it. And if they have a severe infection you have just told them to erase any clean restore points they may have.

Other than that, there are some very good points made.
