Prior to 10/07/2016 my Norton 360 Security History recorded activity that I could use to trace the time of PC turn on, user log in and user log out. These activities were “NDIS filtering is enabled”, User logged in” and No user logged in”. Since 10/07/2016 the Security History no longer records these activities. What could have happened that caused this change in behavior? Could there be other activities that are also no recorded?
