Defender & cant turn on real time protection

Hello

In Virus Threat & protection settings Real Time protection & Cloud Delivered Protection is off with a message that this is managed by your administrator (I am the admin)

I think I have the residual bits of  of a malware or virus scanner free program I tried a few weeks ago but I cant remember which one I installed and thought that I had removed

Any ideas on how I can resolve this?

Thanks

Hi,

My name is Angel. I am an Independent Advisor. Thank you for posting in Microsoft Community.

Open Start, type: regedit
Right click regedit
Click Run as administrator

Navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SecurityHealthService

and modify the Start value from 4 to 2. Restart your computer to re-enable the Windows Defender Security Center Service.

Press Windows key + R
Type: services.msc
Hit Enter

Press Windows key + R
Type: services.msc
Hit Enter

Scroll down to Windows Defender Security Center Service
Double click it
Set its Start up type to Automatic

Click Start
Click Apply then OK

Restart

If that does not work, perform a repair upgrade.

Thanks for the replies, not sure why disabling defender would work? its running with an exclamation mark, when I update and reboot it ok for a while then the exclamation mark comes back, if I scan nothing comes up, but when I go to the Virus & protection page 

Real Time protection & Cloud Delivered Protection is off with a message that this is managed by your administrator (I am the admin)

Hello

Thanks for all the replies but none worked, I ended up deleting the Windows defender folder\keys in regedit then setting all the defender\security settings in gpedit to not configured and that sorted the problem
