Windows 10: Windows Defender's Virus and Threat protection is not working

Hello,I've recently installed a malware my mistake and it destroyed my Windows Defender's Virus and Threat protection completely. All the files related to it is completely erased. I tried all possible commands in Command Prompt and Powershell. I tried to reinstall my windows using update and it didn't work. I'm not able to download updates related to defender . My version of windows is Windows 11 Home. Can someone give a solution to this? Most importantly I don't want my files and apps to be deleted.

:)

 

Virus and threat protection not working

Hi there, I recently reinstalled my windows and the Virus and threat protection is down! I have found that I am missing the 'Windows Defender Advanced Threat Protection Service ' and 'Windows Defender Security
Center Service' files from my services list, I have looked into this and can find no solution to fixing this issue, if anyone can help it would be much appreciated!!

 

Cannot turn on Windows Defender virus protection

I had the same sort of symptoms. In the Windows Security Center, under Virus and threat protection, it said "Your virus & threat protection is managed by your organization."





I note you mentioned the Registry Keys under HKLM/SOFTWARE/Microsoft/Windows Defender. Nice spotting, but it seems like there is another key that is causing the problem for some users.

Steps to a solution:

1. Press the Windows key and type "regedit"
   
2. On the regedit icon that appears, right-click and select Run as Administrator.
   
3. Navigate to the folder located at HKLM\SOFTWARE\Policies\Microsoft\Windows Defender (You can paste this into the address box at the top of the window, or navigate manually using the side directory structure)
   
4. In this folder, there are probably two keys. Right-click and Delete the DisableAntiSpyware key.
   
5. Exit regedit, and return to the Windows Defender settings screen (refresh it if necessary). Windows Defender should have the scan options available and working.
