I couldn’t figure out how to stop “windows defender antivirus service”

Defender AntiVirus

There are 4 options under Defender. Two refer to AntiVirus; AntiVirus Network Inspection Service & AntiVirus Services. Under Startup Type these two are listed as manual and the Status column said Inspection Service is running. When I clicked on the Start
button in Properties, I got an immediate message: "Win.. Def.. Anti.. Serv.. on local comp.. started and then stopped. Some services stop automatically if they are not in use by other services or programs."

 

Turn off windows defender and alerts and stop service

Hi Clifford,



Follow these steps to start Windows Defender Service:

• Open Run command box by pressing Windows Key + R.
• Double-click the Windows Defender service, and then in the Startup type box, click
  Automatic.
• Click OK.

If it is already set to Automatic, then stop the service and
start again.

Let us know the results.

 

How to stop Windows Defender Antivirus from downloading updates

Moved from Windows Updates section, as suggested

I'm running WIN10 Home edition v1909 and Avast antivirus.

Since the upgrade to WIN10 v 1903, I've been getting an error message telling me Windows Defender Antivirus update(s) have failed and specifically - "..Security Intelligence Update for Windows Defender Antivirus "WDA" - KB2267602 (Version 1.305.2729.0)...Error 0x80070643...Retry".

Control Panel -> Adminstrative Tools -> Services reporst that WDA is turned off. Despite this, WIN10 continues to download Windows Defender updates, it then finds it cannot install the updates. I'm wondering if that's because WDA is not running and that's why I'm getting the above error message.

Would stopping WIN10 seeking the WDA updates stop the error messages being generated and, if so, how can I stop WDA seeking the updates. The WDA registry is protected.

I have 15 WDA updates showing as failed updates. All other Winodws updates load immediatley, with no problem.

Update:

Actually I've spend a few weeks trying to fix this. I believe my probelm is uncommon. For example, it only affects my Windows Desktop PC but not my - or my wife's - WIN10 laptops.

I have tried many possible solutions, too many to list here, ranging from checking the Windows Update Troibleshooter through to an In-Place Windows 10 upgrade.

I cannot run an On Demand scan using WDA beacause WDA is not running. If I turn off my (main) antivirus software (Avast) then Start WDA via Control Panel -> Administative Tools ->Services Settings - I see WDA starts for only 5 seconds then turns off again

...is there a way I can stop Windows 10 Home v1909 from trying to update Windows Defender Antivirus
