Event ID 16 - Error while updating Windows Defender status to SECURITY_PRODUCT_STATE_ON!
I performed a clean install of Windows 10 April 2018 Update (created media using the Microsoft Media Creation Tool) on a brand new WD hard drive I bought and installed Norton Security!
Initially I didn't have any issues, but after some Windows 10 updates (not sure which one[s] specifically), Windows Defender is detecting and removing threats when it should be disabled since I have Norton Security installed! I could only access threat history by clicking on the notification warning me that threats has been detected and removed and not by opening Windows Defender which is problematic!!!
I alos noticed a lot of errors in the Event Viewer with ID 16 that reads: "Error while updating Windows Defender status to SECURITY_PRODUCT_STATE_ON."
It seems to me that Microsoft released an update that re-enables and reinforces Windows Defender and it clearly causes issues when other Security products are installed!
