Update information

This anti-malware platform update contains the following improvements:
  • Improved detection for Potentially Unwanted Applications (PUAs). This blocks PUAs from being downloaded through Internet Explorer, Firefox, and Chrome. It also detects PUAs in the following circumstances and locations:
    • A file that has Mark of the Web (MOTW)
    • A file in the Downloads folder
    • A file in the Temp folder


    It will not detect outside these folders and will not remove already installed PUAs. You must turn it on by configuring the following registry subkey:

    Registry location:
    HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Microsoft Antimalware\MpEngine

    DWORD name: MpEnablePUS
    DWORD value: 1

  • VDI improvements to the UI to better handle multiple remote sessions and to prevent any user from rebooting the machine if a malware clean-up requires a reboot. Administrators can control this by using this GPO.

    Registry location:
    HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Microsoft Antimalware\UX Configuration

    DWORD name: SuppressRebootNotification
    DWORD value: 1
  • Virtual machine performance optimizations concern memory usage and initial VM load time. A script is available to allow signatures to be downloaded one time on the host server and reused by the VMs. This saves network bandwidth when downloading the signatures. For information about the script, click here.
  • The hash (SHA1) of detected threat files can be recorded in the event log for additional research and correlation with other threat streams. To enable SHA1 logging, configure the following registry subkey:

    Registry location:
    HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Microsoft Antimalware

    DWORD name: ThreatFileHashLogging
    DWORD value: 1

    When a threat file is detected and hash logging is enabled, EventID 1120 is recorded in the System log.
