A few weeks ago I had problems with running Rocket League on my desktop. I asked around on Steam and they said 'Try turning off your real-time scanning'. This worked for me but it's really annoying to turn it off every time I want to play. Yesterday I discovered it's not only Rocket League but also Super Meat Boy. Never had problems before with McAfee closing or crashing my games.
I know I can whitelist these on my own but it's still annoying..
