Fix error: Virus and threat protection page not available in Windows 11

For those who are for any reason facing an error on their system while accessing the Microsoft default Antivirus, here is the solution. You may get some errors like the Virus and threat protection page is not available because your IT administrator has restricted that in Windows 11…

I was using Windows 11 which is the latest operating system of Microsoft with the latest security features. But after installing a few software and activating the Windows, a key feature that is built-in security to protect your PC from various threats vanished. One of these features is “Virus and Threat Protection,” which provides real-time protection against malware, viruses, and other security risks. However, somehow I recovered that and there would be other users who may encounter the same issue where the “Virus and Threat Protection” page is not available or inaccessible. So, In this article, I will provide a few ways to resolve it.

Error:

Page not available

Your IT administrator has limited access to some areas of this, and the item you tried to access is not available. Contact the IT helpdesk for more information.

Method 1: Disable Windows Defender UI Lockdown

Maybe because of any reason the User Interface of the Windows Defender that also includes the “Virus and Threat Protection” page is disabled. So, first let’s run a command that can enable it again, if that is the problem.

For that, open PowerShell as Admin. You can right-click on the Windows start button to select it.
After that, run the following command in the PowerShell

Set-MpPreference -UILockdown 0

Now, open your Windows Defender or Virus and Threat Protection page.
Quite good chances that you will have access to your system’s default Antivirus.

Method 2: Using Regedit

If the above method doesn’t work then you can follow the following in which we use Regedit to add a few values.

Open Regedit. Press Win+R and type – regedit after that press the Enter key.

Navigate to HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows Defender
Right-click on the empty area and select New -> DWORD (32-bit ) value

Create new entery for Window defender in registery

Give it a name – DisableAntispyware
Similarly again create a value with the name – DisableRealtimeMonitoring
Let the value default value 0 as it is. Close the Registry Editor and restart your system.
Now, check if Windows Defender is available with its apps.

Method 3: Check for Windows Updates

Outdated or missing Windows updates can sometimes cause issues with security features. To ensure that your system is up to date:

Press Win+I to open the Windows Settings.
Click on “Windows Update.”
Select “Check for updates.” If updates are available, install them.
Reboot your computer if prompted.

Method 4: Reset the Windows Security App

Sometimes, issues with security services can cause the “Virus and Threat Protection” page to become unavailable. To reset the app:

Press Win + I and select the Apps.
Type – windows in the search box window.
Click the three dots given in front of the Windows Security App and select Advanced options.
Click on the Repair button first, if after that you don’t have the Virus and Threat page then Reset the App.
Now, try accessing the “Virus and Threat Protection” page again through Windows Security.

Method 5: Use Windows PowerShell

If the issue persists, you can try using Windows PowerShell to reset the security components:

Right-click on the Start button and select “Windows Terminal (Admin)” to open an elevated PowerShell window.
In the PowerShell window, copy and paste the following commands one by one and press Enter after each:

Get-AppXPackage -AllUsers -Name Microsoft.Windows.SecHealthUI | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Get-AppXPackage -AllUsers -Name Microsoft.Windows.SecHealth | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Restart your computer after running these commands…

Select “Recovery” from the left-hand menu.
Under “Advanced startup,” click on “Restart now.”
