Hi Red, This is Ramesh.
If uninstalling McAfee using the Apps and Features doesn't help, try the standalone McAfee products uninstaller tool.
Download MCPR from McAfee's site:

The instructions are here:

Another option is to use Revo Uninstaller to remove all traces of McAfee.
Note:
The above tool doesn't remove McAfee Security Scan Plus. If you want to remove it, run "C:\Program Files (x86)\McAfee Security Scan folder\Uninstall.exe".
