Try Regscrub click here Have you uninstalled F Secure completely? To the best of my knowledge F Secure and Spy Sweeper are not compatible. When I installed F Secure I'm sure I was asked to uninstall Spysweeper. If Regscrub doesn't solve the problem, I would be inclined to reinstall F Secure and then uninstall it again. I can take quite a while so don't get impatient. F Secure Internet Security 2006 is one of the best on the market in my opinion.
