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.
