When doing major upgrades or downgrades such as 8 to 8.1 or back it's wise to completely uninstall McAfee during the process as it may interfere with the process and will almost certainly become corrupted anyway.

Uninstall McAfee via Control Panel > Programs and Features

Then run the MCPR cleanup tool and reboot

Reinstall from your online account.
