Your insights and guidance would be highly appreciated to ensure my system's security.Thank you for your prompt attention to t

    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. Windows Defender notification of malware detection

    Hello,

    Thank you for keeping us posted and we appreciate your continued patience on this issue.

    At this point, I suggest you to update the Windows Defender program and check if it helps.

    To check for new Windows Defender definitions manually:

    • Open Windows Defender.
    • Click the arrow next to the Help button, and then click Check for updates. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

    Also, check if the detection is of the same malware file or not. Again, see if it is any specific program or a file you try to access which triggers the detection.

    Additionally, view the log in Event Viewer to check if the malware is removed every time it is prompted.

    To open the Event Viewer. To do so, follow the below steps.
    • Go to the Control Panel and choose to click on the
      Administrative Tools icon.
    • The above action will open up a new window of the Administrative Tools where you will see the
      Event Viewer.
    You can view Windows Defender "Operational" events in Event Viewer under Applications and Services Logs -> Microsoft -> Windows -> Windows Defender.

    Kindly keep us posted, for us to be able to assist you further.

    Thank you.
