Get AVG for your anti-virus software (it's free here)
Then.........download and install 'SpyBot Search and Destroy'

Then, remove McAfee - and don't use it again. Install AVG. It is the best anti-virus on the market (has been for 10 years, or so).
You can keep malwarebytes, just run it separately from 'SpyBot'. (always search for updates).
I replaced it with Avast, and all seems good.
Do NOT use AVG. It totally crashed my computer. Their support tech was no help. Had to buy another computer.
