Trend Micro Officescan v8 is sometimes not uninstalling completely/cleanly.


  • SEP I/C v7.0 - Pre SP1
  • Trend Micro Officescan v8.0

Sometimes this version of TrendMicro is not fully detected for uninstall due to a non-standard or modified install.


This issue will be resolved in SEP I/C 7.0 SP1

In previous versions of SEP I/C 7.0, Add the following to the AVDetectNUn-install.xlm file. It can be located at the following path:

\\NSCap\bin\Win32\X86\Symantec Endpoint Protection\Uninstall Package\

Also, the "Altiris Service" will need to be restarted after the update in order for this change to take affect.
