For the sake of brevity, I'm going to 'second' the above, except we've been paying for Premium on 3 machines for a 2+ years.
MBAM 3.6.1 has been causing 'hard' hang on a fresh install of: Windows Enterprise 7 sp1. Installed MBAM on 12/28/2018.
Only way to restart system was via Power Button (holding it for 8+ seconds). No blue or black screen, just DWM freeze.
Hardware: Dell T3610 Precision Workstation, Nvidia Quadro, Intel DC-S3520 SSD
Software: MS Office Pro Plus 2010, Adobe CC 2018
After removal of MBAM today (1/1/2019), not a single hang or freeze.
(wasted 2 days on event logs, hardware swaps, testing... finally decided to rollback/remove MBAM)
