Similar here, a day or two ago. Win7 x64 Pro, fully updated. Malwarebytes Premium would announce all realtime protection turned off, then on, then off... Roughly every hour. I think it was something to do with an auto-update to Component package 1.0.508. I restarted Malwarebytes, rebooted, to no avail. But eventually it sorted itself out and I've had no further problems. I manually updated other computers (Win7, 8.1, 10) to 1.0.508 once the original computer had settled down, and on those it produced no problems. A mystery!
