Application Problem

To isolate the problem:

  1. While the UMH module is enabled, execute the program to try to reproduce the problem. Refer to the following KB to make sure UMH is enabled: Enabling/Disabling User-Mode Hooking (UMH) in OfficeScan (OSCE).

    If the problem can be reproduced by enabling UMH, and resolved by disabling UMH, it is a UMH-related problem.

     
    After UMH status changes (enabled/disabled), terminate the process, and then restart the process again.
  2. When the problem has been reproduced, confirm whether the process of this application is running or not. Process Explorer can assist to check and confirm this.
  3. If the application's process is still running while the problem is being reproduced, collect the UMH debug logs. Below are the reference KBs:
  4. If the application's process is not running while the problem is being reproduced, collect the application crash log for the UMH module. Refer to the following KB: Collecting logs for the User-Mode Hooking (UMH) module for an application crash issue.
  5. Provide the execution file of the application's process to Trend Micro Technical Support, if possible.
  6. Provide an installer of this application to Trend Micro Technical Support, if possible.

System Problem

For system hang:

  1. Log in using Safe Mode. Refer to Step 1 of the following KB: Collecting logs for the User-Mode Hooking (UMH) module for a system crash issue.
  2. Navigate to "%windir%\system32\drivers\":
    • Rename "TMUMH.sys" to "TMUMH.sys.bak"
    • Create a folder in the same place. The folder's name is "TMUMH.sys".
  3. Reboot the system to normal mode to reproduce the problem.

    If the problem fails to reproduce, it is a UMH-related problem.
