Performance-related issues caused by Behavior Monitoring and Device Control

Updated over a week ago


This article explains how to identify and resolve performance-related issues caused by Behavior Monitoring and Device Control.

Detail Steps

Performance dropping is more complex than the software blocking issue. However, you can use TMPerfTool.exe to find the high-loading running process and add it to the Behavior Monitoring Exception List or contact Trend Micro Technical Support for further assistance.

To use the TMPerfTool:

  1. Contact Trend Micro Technical Support to obtain TMPerfTool (32/64 bit).

  2. Place the TMPerfTool.exe file in the same folder as the TMBMCLI.dll file. Usually, TMBMCLI.dll is in the main folder of products.

    • Trend Micro Internet Security's default installation folder is %ProgramDir%\Trend Micro\Internet Security.

    • Worry-Free Business Security's default installation folder is %ProgramDir%\Trend Micro\Client Server Security Agent.

    • OfficeScan's default installation folder is %ProgramDir%\Trend Micro\OfficeScan Client.

  3. Right-click TMPerfTool.exe and select Run as administrator.

  4. Click Analyze. The Trend Micro Performance Tuning Tool will start to monitor the CPU usage and event loading. If a red highlighted row appears, it means that the Trend Micro Performance Tuning Tool found a system-intensive process. In the example below, the process is mspdbsrv.exe.

  5. Select the highlighted row and then click the plus (+) button to add this process to the exception list.

7. Verify the CPU usage. Do one of the following:

  • If the performance did not improve, click the Undo button to undo all the changes. Select another highlighted process.

  • If the performance improved, select the process and then click the minus (-) button. However, if the CPU usage increases again, then you have found the system-intensive application.

    To resolve the issue:

    1. Add it to the product’s Behavior Monitoring Exception List. Please refer to the respective product’s Administrator's Guide for more details.

    2. Contact Trend Micro Technical Support and provide the information below:

      1. Take note of the name of the application.

      2. Click Stop.

      3. Click the Export button and then save the XML file in a specified folder.

      4. Pack the XML file report, high I/O process name, and screen-shot.
