7. Delete the ServerProtect Devices:
   1. Go to the Control Panel > Administrative Tools > Computer Management.
   2. On the System Tools tree, select Device Manager.

   4. Delete the following devices:
      • Trend ServerProtect Prefilter (Windows 2003 only)
      • Trend ServerProtect Filter
      • Trend ServerProtect Scan Engine
      • StartAG
      • StartNS
       

      Deleting the devices may require you to restart the machine especially if you want to reinstall the SPNT Normal Server or the OfficeScan client.
