It should be easy to fix.
Boot into safe mode and after you login, click no at the prompt to do a system restore. Restore to a date before you applied those settings.
Boot into safe mode with networking, clicking yes at the prompt, and open IE, download mbam. Run, install, open, update, scan, remove items.
This should clear it up.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
