Trend Micro OfficeScan–Manual UnInstall–Automated

Recently I’ve been having issues on a few workstations where the Trend Micro OfficeScan installation became corrupt. Attempting to re-install OfficeScan again would result in an error message saying it was already installed. All the tools that Trend Micro provided wouldn’t remove the remnants. Trend does offer a manual uninstallation method (, but takes too much time to perform on multiple workstations.


I created a VBScript that automates the manual uninstallation instructions. For a small portion of the code it depends on Microsoft’s DevCon utility ( and won’t run without it. Please extract the DevCon utility to C:\Windows\System32.
