The real answer is to get rid of mcafee. It is one of the most intrusive, and least effective, antiviruses available on the market.
i beg to differ, i think norton home edition is the worst. it was normal for the computer to error and bluescreen after it being uninstalled.
but yeah it probably thinks your computer is a victim of a bot net and i know there are some that use computers to mine so it would make sense even-though it has an benevolent use on your machine.
