Windows 10: How to get Virus and Protection icon back? Windows 11

I have tried the cmd method, powershell, and group method. They did not work right away, then about 30 minutes later it appeared. I shut down the computer for the night and the next day it was gone again. I can't help but to feel that my device is vulnerable to attacks due to the Defender software having glitches.

Hi all, i am having trouble running a virus scan, my virus and protection is unable to launch.
I have recently gotten a lenovo ideapad gaming laptop, running windows 11 pro and ever since i can not launch virus and protection.

I have followed the below steps, however i am still stuck with the same issue,

1. Run SFC and DISM
   
2. Repair & Reset Windows Security
   
3. Restart Windows Security Service ( unable to restart, option is greyed out)
   
4. Check your Date and Time settings
   
5. Turn on Virus and threat protection settings ( unable to as it isnt in windows security panel)
   
6. Turn on Real-time protection ( same issue as above, it isnt available)
   
7. Uninstall any other third-party antivirus
   
8. Run a malware scan with ESET security
   
9. Fix: Windows Security Virus & Threat Protection missing using Local Group Policy Editor
   
   1. Computer Configuration\Administrative Templates\Windows components\Windows Security\Virus and threat protection
      
   2. Select “Not Configured” or Disabled to show the Virus & threat protection in Windows Security.
      
10. Using Registry Editor
    
    1. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender Security Center\Virus and threat protection
       
    2. Set the value to 0 to show. Or you can also delete “UILockdown” to show the Virus and threat protection.
       
11. Use PowerShell
    
    1. Set-MpPreference -UILockdown 0
       

Please could someone help me, i feel really compromised without the ability to access virus and protection settings.
( Note, the only other program which may have a conflict that i am running is lenovo vantage)

1. Avira AntiVir Personal Classic Edition
2. Avast! Home Edition
3. AVG Free

Avira Is Found To Trigger Less False Alarms Than Anyother AV (Even Paid Don't Have That Kind'a Accuracy), & Is Much Better Than some of The Paid Ones. Next Is Avast!, For It's Individual Scanner Protection & It's Unique VRDB (Virus Recovery Database) Feature.

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.
