Windows 10: CAN'T ACTIVATE WINDOWS DEFENDER....."SECURITY AT A GLANCE" IS BLANK.... "VIRUS & THREAT...

Hello to all,



These are all symptoms, that theWindows Defender Antivirus Service is missing from your PC.


Display the "Services" screen and scroll down to the Windows Defender services. W10 Pro should

have 4 services described, and W10 Home should have 3 services described. You will probably find

the service named above is not there. This problem is becoming more prevalent!


Apparently, some form of malware, that Windows Defender does not identify, is removing this Service.

If in your process of repairing this problem, you run MalwareBytes to clean your PC, please report back

what it finds, from its Detection History. Since this malware is not identified by Windows Defender.

It may be nothing more than a PUP with apunch. Probably a good idea to set your WD for PUP detection.



If you find that Windows Defender Antivirus Service is missing, there are probably only two ways to

restore it. Please see my response in this thread. https://answers.microsoft.com/en-us...activate/c64676e9-8982-4405-bc47-13ed4799a353


Any questions regarding the link? Please respond.

Suppress "Windows Defender Antivirus did not find any threats..." notification on Windows 10

You can turn off Enhanced Notifications for Windows Defender:

1. Press Windows + i.
   
2. Click Update & Security.
   
3. From the Update & security sidebar, click Windows Defender.
   
4. Scroll to the Enhanced notifications section and select No.
   

If you do not see Enhanced notifications as an option (likely because you are running Windows 10 15042 or newer), include the following additional steps:

1. Click Open Windows Defender Security Center.
   
2. Click Virus & threat protection.
   
3. Scroll down and click Change notification settings.
   
4. Turn off Receive recent activity and scan results.
   

This will turn of successful updates and only notify you critical events.

 

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.
