If you still have adds pop ups and your computer is running slow this is the best cleaner you can find. This is a safe link added for the download.
Malwarebytes Keep running this scanner. Then run a system clean up. Reboot and repeat till the scanner comes up clean.
This will take that annoying McAfee the heck off too. I use avast and Ad-ware to keep clean too but the above will get in a clean parts most all other cleaners will not get.
