|1st of all, McAfee is a dog...now here's why you can't fix your problem.|
Run these 3 in EXACTLY the order listed and don't reboot until after the last scan
1- rkill.exe (stops the malware process)
2- tdss killer (helps to quarantine the unwanted rootkit if found)
3- Malwarebytes (run a full scan and fix all it finds.
If that doesn't work...do the ENTIRE thing again in Safe Mode
