Thanks for the reply. I don't think that I should have to set my computer's power management policy to conform to MBAM's scheduler! If MBAM is supposed to run on a schedule, then it should a) WAKE my computer, if necessary to run the scan that I scheduled, b) finish the scan that I scheduled before returning my computer to its sleep/wake preference. MBAM can acknowledge that the computer requests a change of state from wake to sleep. It either does not do so, or does know how to deny the request for a change of state. What I think you are saying is: "MBAM will run scans only if the computer is awake and stays awake for the duration of the scan...plan your computer's sleep/hibernation schedule at your own risk." Is the tail wagging the dog?
