Windows 10: can't turn off windows defender periodic scanning

Hello, I turned on windows defender periodic scanning just to test it, but when I went back into settings to turn it off again, the settings options had changed and the toggle switch had disappeared, so it is no longer possible to switch it off. I've tried to follow the directions I see online by going to settings>update and security>windows defender, but for whatever reason, my settings doesn't have the "windows defender" directory. Instead where it should say "windows defender" in the sidebar, it reads "windows security," and when I click on this, there simply is no option to turn off periodic scans.

Defender Periodic Scanning or Offline Scanning?

That link does suggest it's useful to use Defender offline scanning in addition to periodic scanning and a third party real time anti virus (e.g. Kaspersky).

 

Limited Periodic Scanning turns off

I use Symantec Endpoint Protection 12.0.1 MP5

In Windows Defender i need to use only Limited Periodic Scanning. SEP is default antivirus.

Microsoft says:

Enabling Windows 10 Limited Periodic Scanning <--- THIS TURNS OFF


If you are not using Windows Defender as your antivirus program on Windows 10, you can enable
Limited Periodic Scanning under Settings.

• Navigate to Settings -> Update & Security ->
  Windows Defender.
• Turn Limited Periodic Scanning on.

 

Limited Periodic Scanning turns off

Hello!

I use third-part antivirus. After Anniversary Update in Windows defender is option Limited Periodic Scanning. I turn it ON, but after 5 minutes Limited Periodic Scanning is automatic OFF. And every time when i restart my PC, i need to turn it ON.

Any suggestions?
