Both Norton 360 and Windows Defender, enabled and real-time
Other discussions said that only one real-time scanner for infectious file checking can be enabled to be turned on; never more than one active or they cause problems. I have checked into the settings of Norton 360 and Windows Defender on two different computers, and find that both are operating and no frequent or troublesome problems occur. Of course, they do not seem to scan at the same time. They are scheduled to scan for the most part, at different times. The W.Defender of both is set to once per week at specified time, and the Norton for the one is set either to a different time during the week and the Norton of the other is set for automatic.
No problems. What am I not understanding?
