TGM,
There is little doubt that it is something in your hardware or software environment causing this, you are the only one that has reported the problem. Malwarebytes leaves a log of its actions, not sure about McAffee, but check there. You might also check your settings in Windows Defender, it can do unpredictable things with zero notification to the user on occasion. I have it turned off, along with Windows Firewall. The Fab v10 installer is a world apart from v9, so the fact that v9 works in not really diagnostic. Anything that block or filters ("guards") your internet connection is a suspect.
