Malwarebyte's and AVG anti-virus are your friend
McAfee sucks hairy balls.
Don't use it ever.
I'd download Malwarebytes and scan it, it will get rid of this virus. I had a few computers last week get the same one, it's been around a while. Make sure, if you have a recovery drive, (usually D: instead of C: with <10GB), that you scan it as well.
It's roots run deep into the Windows file system.
After you get rid of them with MBAM uninstall it then install AVG Free
