Yes and it found 91 problem and could only fix a couple
I ran it again straight away and it found a 140
I was looking for a file which I eventually found (Sorry can't remember file name off the top of my head)

You may have malware onboard that is preventing McAfee from functioning properly so try some of the tools suggested here: https://community.mcafee.com/docs/DOC-2168
McAfee does have a virus removal service but it is expensive so let's try to clean it up here.
The installation also could be corrupted for whatever reason and then one is advised to uninstall in the normal manner via Control Panel/Programs/Uninstall a Program, then run the MCPR cleanup tool (see Useful Links at top of page), reboot and reinstall from the online account.
