How to remove the notification "Unauthorized actions have been detected..." permanently?

Question

Android

After recovering some deleted files, a notification from KNOX began to appear "Unauthorized actions have been detected. Restart your phone to undo these actions." Restart does not help, like other shamanism with a tambourine. Could you explain step by step how to solve this problem without uninstalling KNOX? Ruth is right, the phone is Samsung A5 (2016). Thanks
