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)

  • Apex One NT Firewall (TmPfw.exe)

  • Apex One Data Protection Service (dsagent.exe)

For this reason, these services are disabled by default on Windows Server platforms. 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.
