I deactivated the Malwarebyte service in the Windows Computer Management fore the time being after it sucked up 90% of my RAM.
<windows><X> then "Computer Managment", then "Services and applications" at the bottom left and then " Services", select "Malwarebytes Service", right-click and select properties. Select "Start type= Deactivated" and ok. If then still running, kill it in the task manager and it will not restart.
This is obviously no solution but should prevent your computer from crashing until MWB have come back with a solution. You may then need to change it back to "automatic".
