We are working on ASP.NET web application -ASP.NET C# at server side and JQuery/JavaScript on client side . We download some exe files from server, however sometime antivirus/group policy/Any registry setting/security policy/any other restrictions block the download of exe file.

Is there any client side mechanism(JavaScript/JQuery) which can detect file has been blocked by any of the above reasons?

If it is not possible by jQuery or JavaScript then is there any other way to find out, if downloaded file is blocked by antivirus.
Also would like to know by what all reasons can cause the download of EXE file on a system.

    Hi @Sandeep ,

    The client language (Javascript, Flash, etc.) is sandboxed into an environment. The browser sandbox means that each browser process (tab, extension) is isolated and they are not allowed to access anything else on your PC.

    Therefore, the requirements you described are impossible to achieve because of the serious security risks.

    The download of the file, I think the reason may be that the user clicked on some buttons or links or similar operations.

    Best regards,
