    I put a file named "Desktop_startup_aaa.cmd" "the Batch File" in my Windows startup folder. When I reboot, and the Batch File is triggered by being in my startup folder, I get the warning, "Microsoft Defender SmartScreen prevented an unrecognized app from starting" "the Annoying Obstruction-Warning", and I have to tell Windows that it's okay to run the Batch file, and I find the delay and the required keystrokes annoying.My default text editor is EditPad Pro fullname/full path = "C:\Program Files\Just Great Software\EditPad Pro 8\EditPadPr08.exe".

    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?

    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.
