1 pointIn managed environments (ie. on machines with the ESMC agent installed) PUA are cleaned as though in strict cleaning mode. The users are not supposed to make decisions and PUAs are controlled by an administrator. An admin can create exclusions for specific PUA detections and also possibly restore files from quarantine remotely.
