For what it's worth: I ran into this problem on my Windows 7 x64. Prior to stumbling onto this forum topic, I suspected it was the Norton software that I run alongside my Malwarebytes installation causing the problem, because on the worse days, I would temporarily disable the "auto protect" on Norton to get any work done. The computer would work fine upon disabling this module, but obviously that wasn't the ideal solution. After coming across the information presented here, it occured to me that the problem did coincide with my update of Malwarebytes to 10508. I have now reverted my installation back to Malwarebytes version: 188.8.131.5211 Component package version: 1.0.482 using the instructions provided here and the problem has been fixed. Malwarebytes, Norton & Windows 7 are all working in concert once again.
