I run a series of tools, each catches another piece of the troublemaker.
The key, first of all, is to reboot in safe mode.
Download these, update them and then run msconfig and start in diagnostic startup.
AdwCleaner
Junkware Removal Tool
Malwarebytes Anti-Malware Free
HitmanPro
Hitman needs to be online, so go back to normal startup, then run it.
The site I got that list from has something on yours, check this out too:
