The following services provide robust protection but their monitoring mechanisms can strain system resources, especially on servers running system-intensive applications:

  • Trend Micro Unauthorized Change Prevention Service (TMBMSRV.exe)

  • OfficeScan NT Firewall (TmPfw.exe)

  • OfficeScan Data Protection Service (dsagent.exe)

For this reason, these services are disabled by default on server platforms (Windows Server 2003, Windows Server 2008, and Windows Server 2012). If you want to enable these services:

  • Monitor the system's performance constantly and take the necessary action when you notice a drop in performance.

  • For TMBMSRV.exe, you can enable the service if you exempt system-intensive applications from Behavior Monitoring policies. You can use a performance tuning tool to identify system intensive applications.

    For details, see Using the Trend Micro Performance Tuning Tool.

For desktop platforms, disable the services only if you notice a significant drop in performance.
