Having the exact same problem as the past few posters. Started a couple of hours ago, seemingly out of the blue.
MBAM starts with web protection disabled after a computer restart. If I attempt to enable it, it never starts, GUI indicates it as stuck in "starting". At that point the MBAM service starts consuming memory until it exhausts all the available memory.
I have added the suggested exceptions SEP and rebooted.
I have downloaded the clean tool and completely removed MBAM and gone through that process (2 times).
I'm attaching the logs collected as instructed in the earlier post.
