|rule number 1...NEVER pay for a product to remove something...it is always a total rip-off.|
uninstall it and use these other freebies that will work for you for free:
2- Trojan remover
3- Hitman Pro
Start with those and see how the PC runs.
BTW you must be talking about spyware doctor, not spy doctor...if so, there is also a free version of that that is fully functional.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
