Windows 10: I can't open the Windows Defender because it asking for an App which is not downloadable.

I'm having this issue since I upgraded from Win 10 to Win 11. I tried all the method that can solve the problem, powershell in administrator as well, none of them worked. Defender removing all my files which are not viruses of course, and I cannot get them back because I cannot open the Defender. Please someone help me what should I do.

Hi Craig,

There's a possibility that the SmartScreen option is on that's why you're unable to install downloaded apps. Let's try to turn it off and see if it helps. See the steps below:

• Open Windows Defender Security Center from your Start menu, desktop, or taskbar.
• Click on the App and browser control button on the left side of the window.
• Click on Off in the Check apps and files section.

Let us know if the suggestion helps you out.
