As stated before App is unistalled l did the finder method and looked for all files and deleted them, of course there was something left behind. Thanks Apple!
If you're comfortable with the terminal, you can run the following command to find where "McAfee, LLC" is configured.
sfltool dumpbtm
That will output the parent/child items that are allowed in run in the background. Under the child item, you'll probably find a few *.plist files listed in ~/Library/LaunchAgents--delete them (or move them to a temporary folder if you want to be cautious). Might have to restart before the thing goes away.
