Hi. I tried to solve for Windows Defender Antimalware/Antivirus Signature Definition Check by installing the latest mpam-fe.exe on Tableau Server but the issue still haven't been solved yet. I've checked solution by following this website. Last update is since last month on last November.

    Hello

    Thank you for posting in Q&A forum.

    Here are a few additional steps you can try:

    1. Ensure that the signature definitions are indeed up to date. Sometimes, the update might not apply correctly. You can manually check the version by navigating to Windows Security > Virus & threat protection > Protection updates.
    2. If you have other antivirus software installed (e.g., McAfee, Symantec), it might be conflicting with Windows Defender. Consider temporarily disabling or uninstalling the other antivirus software to see if the issue persists.
    3. Verify the registry keys related to Windows Defender signature updates. Open the Registry Editor and navigate to:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Signature Updates

      Ensure that the keys and values are correct and up to date.
    
    1. Ensure that the server has proper internet connectivity to download updates. Sometimes, network restrictions can prevent updates from being applied.
    2. As a last resort, you can try reinstalling Windows Defender. This can sometimes resolve underlying issues with the software.

    I hope the information above is helpful.

    If you have any questions or concerns, please feel free to let us know.

    Best Regards,
