    Blocking potentially unwanted applications


    Hi.

    For people using Windows 10 Home1909, is their a way to set your windows defender to block PUPs and PUAs? And I know that the new Edge has an option to do this but is their a way to make this a system wide setting?

    Thank You.

    :)

  2. blocked applications

    Hi Eileen,

    Windows Defender or another antivirus software will sometimes block a certain app or file from running or being installed. With this, you can check the
    quarantine section of the antivirus program you are using to see which program is being blocked. To better assist you, we need the answers to the following questions:

    • What is the exact error message did you receive after launching or running the app?
    • Which antivirus program are you using?

    In the meantime, we suggest disabling the Windows Defender SmartScreen and see if the app will run. To do this, simply follow the steps below:

    • Type Windows Defender on the search box and click on the first option.
    • On the left side of the window, click on the Window icon (App & browser control).
    • On the SmartScreen for Windows
      Store apps column, select Off.

    We are looking forward to your response.

  3. Can't launch any applications

    Hi,

    This error message will show if the application or program that you are trying to open was been blocked by Windows Defender SmartScreen. Having said that, we suggest that you disable Windows Defender SmartScreen by following these steps:

    • Click on Start.
    • Type Windows Defender Security Center.
    • Click on App & browser control.
    • Click on Off in the following options:
      • Check apps and files.
      • SmartScreen for Microsoft Edge.
      • SmartScreen for Windows Store apps.
    • SmartScreen is now completely disabled. If you'd like to still receive a warning when a potentially malicious file or program is detected, you can choose Warn in each SmartScreen option.

    Let us know if the steps above helped you to resolve the issue.

  4. Blocking potentially unwanted applications

    Can't get the Windows Defender team to analyze a potential incorrect detection

    Hi Mike,

    Since PUA(Potentially Unwanted Application) protection feature allows Windows Defender to detect and block certain apps that are not categorized as threats, but they increase the chances of your device being infected with malware or it may affect your device's
    performance. That might be the reason why the PUA protection feature detects the software. In the case that the feature blocks an application you know that can be trusted, you may follow these steps to allow the app:

    1. On the start menu, type Window Defender security center and press Enter.
    2. On the pop-up window, select Virus and threat protection.
    3. Click Threat history option.
    4. Under Quarantined threats, select the file, and click Restore button.
    Note: You can also click the Remove button to get rid of the unwanted app and other infected files.

    After performing the steps above, it will restores the app to its original location.

    We'll be waiting for you to post back.
