About 2 years ago I used to use Spyware Doctor, it is 1000 times better then Ad-Aware, and it finds alot more stuff, it even checks your SVChost and deletes any malicious code that was added onto the windows file (So it prevents tracking cookies from being created automatically and from your info being logged). The only problem now is that Spyware Doctor is no longer free

So just use Ad-Aware. its not as good, but it will get somewhat of the job done.
