If the antivirus is worthless, but you can't remove it, try searching for an uninstaller on the Web. Since the trouble started since you installed it, I blame the antivirus.

I doubt you're the first one who have the same problem if it's the antivirus. If so, try googling something like '(name antivirus) help uninstall'. You should get useful links with that.
