Windows 10: Windows Defender Security Service Stops Every 10 Minutes

When it shows as stopped it means I cannot scan until I restart it. I can restart it through Task manager or Services but that's not the way it's supposed to work? Any ideas.

I am 99% certain it's not a virus. And I do not have another another antivirus installed. I've tried it with or without Malwarebytes and that has no effect.

Defender update locks up

When using The Update and Security option in Windows 10 it tells me updates are available and downloading. Defender definition update is listed. It never completes. Downloading continues to be shown and the Defender definitions message keeps coming and
going every few minutes. No way to stop the cycle. Anyone have any help?

How to permanently stop Windows Defender in Windows 10

I've gone through the Defender program > Settings> Update & Security tab > Realtime Protection [turned off]. Every time I restart my Windows 10 PC Windows Defender is running again.

I can not stop the process in Services and can not find any way to keep it from repeatedly starting.

 

Hi, not heard of this before.
Event id 500x or so may be relevant, but may not help with identifying the cause.
Windows Defender AV event IDs and error codes | Microsoft Docs

If one of those gives you the exact timing, that might give a little more info.

Try creating a new user for test purposes, and see if the same happens then.
If not, you can try examining the differences in what's running, including scheduled tasks.




Note dependency:




Please post a screenshot of Defender's GUI, Virus & threat protection.

 

Thanks for the reply. I'll try creating a new user.
As per attached my image corresponds with yours with the exception that your Centre Service is running whilst mine has stopped- on its own. The dependencies are he same.

 

Never got the opportunity to try a new user because a new build came out and it installed. The new build keeps Security Centre Service running but now I have a new problem in that I cannot open Security Centre from 'Settings'. I can live with that though.

Thanks for the suggestion.

 

After installings Antivirus on Windows 10 Windows Defender Security disable so possibility there cannot be two(es) on the same PCs, please I need help from experts,

Sincerely yours

Yes, that's normal. Why do you need both to function?
