I am new to this forum but I had the same issue starting today. My PC was non responsive and I attempted to reboot. With a reboot it was still unresponsive. Task manager showed 97 percent memory usage. I have a ton of RAM so I was shocked, especially since nothing much was running. I got into the performance manager of task manager and saw MalwareBytes was taking all the memory. I tried to stop it running and gor "Access Denied" errors. I had toplay with the timing to reboot and IMMEDIATELY uninstall MalwareBytes . First attempt gave access denied errors again, but eventually was uninstalled. After a new reboot, PC performance was normal again. Note, I am a paid premium member but I am afraid to re-install MalwareBytes at this point.
