Found a way to disable/uninstall Trend Micro without the password.

Just change it. here’s how

I had the same problem because it was a Corporate edition. Follow these steps, it worked for me.  To remove / reset the uninstall password for Trend Micro OfficeScan, Edit Ofcscan.ini file. ( If it’s not in your Tren micro program folder, just do a search.)

  1. Open the Ofcscan.ini file using notepad or the text editor of your understanding.
  2. Control-F and search for the [INI_CLIENT_SECTION]
  3. Find the line reading Uninstall_Pwd= and comment it out with a #.
  4. Insert a new line saying Uninstall_Pwd=70
  5. Save the Ofcscan.ini file and retry the uninstall. When it prompts you for a password, enter a ‘1′.

This has worked for me! Peace. Now to try it on my vista machine - it may not work because i mangled the registry. :-(
