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.


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.

Virus and threat protection page not available in Windows 11

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.
