uiStub incompatible

I have Windows 7 and Norton 360 installed. After an infection with SpyHunter and other viruses (which Malawarwbytes took care off) I can not turn on Norton, uninstall it, use compatiblity action in "troubleshooting"  or applying Microsoft "fix it " actions. The recurring message is " unspecified error C;\Program files (x86)\Norton Internet Security\Engine 64\21.7.011\uistub.exe ". I have also restored the computer to a previous date when supposedly Norton was on and working.

Can please anyone help. I wish I knew more to be more technical but I am stuck and tired of not finding a solution that common sense dictates.Thanks
