I've tried all the things you suggested in your reply and all the scans come up clean. Could it be that a prior virus has left damage to my PC eve though the virus has been removed? Its still exceptionaly slow.
Hmm do you use registry cleaners?

1. Is AVG now removed fully by its removal method?
2. Try uninstalling Mcafee and reinstalling it via
reboot and run
Reinstall from your account.
Is the speed back to normal?
