I think I get it now. Pretty funny. MWB version 3 takes up so much of my i7 PC's resources that it is unusable. After attempting to open Firefox, and after waiting about 3 minutes and it still didn't open, I see MB is taking up over 700 MB of RAM. Nearly 100% of resources being used. After attempting to open Task Manager to kill MWB (again), and after waiting 3 more minutes for Task Manager to open, I was finally able to kill this miserable beast. Now my computer runs normal.
As I said, pretty funny how an anti-malware program prevents malware by not allowing you access to your browser.
You guys really need to address this. I have it on three Windows 10 x64 machines and the problem affects all three.
