    Microsoft Defender Smartscreen

    Hi COLINGILBERT1,

    Sorry to hear you're experiencing this issue. I'm an Independent Advisor and consumer of Microsoft products just like you. Let me help you with your concern.

    Microsoft Defender SmartScreen checks downloaded files against a list of reported malicious software sites and known unsafe programs and against list of files that are well known and downloaded by many Windows users. If the file you downloaded is on the malicious
    list or is not commonly downloaded it will show a warning, advising caution. If you believe that the file is not malicious and you trust the source then you can ignore the warning by clicking "Run anyway".

    Refer to the below link for the benefits of Microsoft Defender SmartScreen.

    Microsoft Defender Smartscreen

    I get this pop up when trying to open an application which I downloaded onto my PC. "Microsoft Defender SmartScreen prevented an unrecognised app from starting. Running this app might put your PC at risk"

    Then it says "Don't Run" or "Run Anyway"

    What is the risk if I press Run Anyway?

    If any one has had this, any advice please?

    Regards

    Colin

    SmartScreen filter prevents an app


    I frequently visit a banking website. Every time SmartScreen prevents being unrecognized app from starting. I start it every time by pressing more info and then Run anyway. Is there any way by which I can add this website as an exception to SmartScreen filter so that it starts immediately bypassing the filter?
