I've had the same problem since this morning. First I tried killing the process in Task manager, but it would restart and over the next several minutes it would chew up all 10GB of RAM. I finally just uninstalled it which was a little tricky and I had to be quick: Kill the MBAMService process, open Control Panel, select Programs, select Malwarebytes, click uninstall - all before MBAMService could chew up all memory! I'm using the Malwarebytes Anti-Malware Premium version, so as a paying customer, I trust this issue WILL be resolved quickly!
