I use both Malwarebytes and Spyware Doctor. Spyware Dr. keeps finding a net-worm.koobface host entry that it's calling osguard-pro.com, 91.212.127.226. I can't actually use Spyware Dr. to remove it due to gripes I have with how they run their business. Malwarebytes does not find it. I have manually searched for files and keys typically associated with koobface, and I find nothing. I can't tell if I actually have the virus on my pc, or if I simply visited the bad website at some point. Any clue? Is there another decent anti-malware that can remove this without gouging my bacnk account?
