SallyMac, I did try to contact John McKenna on your behalf, who knows about Brute Force Uninstaller, but it may be that he's away from his computer at the moment or I think he'd have posted here for you.
This link may help you with System Restore
I have also heard that Prevx is very good at sorting out the problem, so if you're nervous of doing System Restore, you might want to try that first. Again, a google should help you find it.
Good luck, and let us know how you get on.
