    Windows Defender detects an .exe as Win32/Bitrep.A Trojan?

    OK, I had this software(earlier version) on another computer and never had it detected as a Trojan. I tried installing the latest version of this software on my new computer and it got detected as "Win32/Bitrep.A" Trojan after about a week of being installed
    and Windows Defender deleted it. I tried re-downloading and then scanned the installation exe with Windows Defender and it detected it as the same Trojan. I then tried re-downloading again and Windows Defender deleted it as soon as it finished downloading.
    The earlier version installation exe wasn't detected as a Trojan. I also tried a update exe to the software that wasn't the same version and nothing was detected. It seems to be with this certain version of the software or the update to this version. The developer
    recommended installing the free version of Avast. Once installed, I scanned the installation exe with Avast and nothing was detected. Is there a Trojan with the software? According to Windows Defender there is. According to Avast there isn't.

  3. C# EXE and MSI considered as trojan by Windows Defender on Windows 10

    Hi,

    I developed a C# exe and a service (Windows Service). Few Windows 10 machines flag that as having Trojan Win32\Critet.BS. Which is false positive. Is there a way to report that to Microsoft and know what
    might be causing it.

    Reason is for a user seeing this warning by Defender is scary. Any link/tutorial or suggestions will be helpful

    C# EXE and MSI considered as trojan by Windows Defender on Windows 10

    Hi,

    Thank you so much for the response!

    I have already done that, final result was that its really false positive and its cleared. But my concern is on distribution of the EXE. If someone will see defender warning and item being quarantined, it will be a problem. Any way possible to know which
    code/part in EXE is letting it detect as Trojan?
