Malwarebytes Service stopped working when performing scan in Malwarebytes Endpoint Protection Posted March 18 Set anti-rootkit scans to be on a schedule on their own rather than engaging the setting to make them run with every scan you perform. Recognizing when to use that will come with experience in dealing with rootkits and knowing the signs of one being there. These scans are highly intensive and ideally should not be ran with other scanning functions, they can also at times crash your system, not just the application, due to the sensitive areas this function scans. This becomes even more sensitive if disk encryption is used. I think however, your true culprit may have been the SP early start. This is the old Chameleon function in an updated form. It sets MB stuff to be read only. Early start pushes that into the Windows loading process. Sometimes files need to change, even ours, we do update after all! This setting restricts this need and can have unintended consequences. I recommend this to only be used if you are dealing with malware that targets MB and nothing else - this was more common in the early 2010's, not so much anymore, but it could see a resurgence. Regular SP mode is fine to engage to prevent your users from deleting items.
