WindowsDefender won't turn off even though a third party AV is install

Recens · 18 Oct 2018

Hi,

I have F-secure installed on a Win 10 pro computer but even though F-secure is installed windows defender is still enabled.
somehow the computer won't recognize F-secure and disable Windows Defender.
I tried reinstalling F-secure same thing nothing changed and if I manually disable windows defender then when opening F-secure it says that "your computer is protected" but in Windows Security Center it says "Your virus & threat protection is managed by your organisation".

If anyone has a solution on how to resolve this problem that would be appreciated.

"Your virus & threat protection is managed by your organisation".

Hi, I believe that is simply MS-speak for 'You or someone has made a change in the registry which corresponds to one that can be made using the group policy editor'.

It's not an error or a problem. Merely indicative.
