Malware bytes updates, stages the DB files, inflates DB files, applies delta updates, deflates and copies updated DB files, then fails to finish the update.
stuff happens I guess, we're only human and we do make mistakes at times, no hard feelings.
Result: empty DBs and failing MBAMCore. MalwareBytes pretty much broken.
Lesson learned? A faulty update not fully checked before various changes are being being applied, resulting in not being able to internally revert and undo the damage done by said update.
I was patiently awaiting a fix, while checking the forums here. PATIENCE
