    When I try to open a program update or new program downloaded using Firefox I get a dialog box with the following message."Windows Protected your PC.Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk."There are 2 action options in the dialog box "Don't Run" or X to close the dialog box. I have tried disabling Microsoft Defender but the results were the same.

    :)

    Windows Defender Blocking Installations of Downloaded Apps

    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.
