Thanks for confirming that even AFTER shutdown you still there WITHOUT OUR CONSENT! Just google how many thousands! of users have this PARTICULAR problem: https://www.google.co.th/?gws_rd=cr,ssl&ei=FmY1WMjhEJeavQThtqioDQ#q=malwarebytes+slowdown+pc I bought MBAM. A mistake.
As I found out, Malwarebytes does NOT STOP if you exit the program. It just keep scanning without caring what the user on PC need. I have a I4470k with 16gb ram and 3.8TB SSD and MBAM just eats away all the power I invested in. That is now OVER. SIMPLE WAY: 1) SCAN your Machine 2) disable scheduler and service 3) When you need it, start MBAM and it will start scheduler and service itself. After that I disable it again in services.
