How to unload/uninstall Trend Micro OfficeScan without password

In my other posting, I did explain how to kill the Trend Micro OfficeScan processes (aka services).  You can read that HERE.

In this posting, I will explain how if you want to permanently remove/uninstall the not so useful anti-virus from your PC.

If you try to uninstall directly from the Add/Remove Program in the Control Panel, you will encounter a pop-up menu asking you to enter the password.  This posting will assist you in case you do not have the password for what ever reason.

Here’s a simple hack for that:

  1. Search for Ofcscan.ini file. Normally the file is located in C:\Windows folder for Windows 95 and Windows 98, or C:\WINNT directory for Windows NT and Windows 2000. In newer operating system, the Ofcscan.ini can be saved in C:\Program Files\ folder.
  2. Open the Ofcscan.ini file using Notepad for editing.
  3. Search for the [INI_CLIENT_SECTION] section heading.
  4. Locate the line starting with Uninstall_Pwd=. Comment the line (make it inactive by typing a # at the beginning of the line, i.e. #Uninstall_Pwd=…..
  5. Insert a new line beneath the existing line as following:Uninstall_Pwd=70
  6. Save the Ofcscan.ini file.
  7. Try to uninstall Trend Microsoft OfficeScan again. When prompted to enter a password to continue to uninstall, enter 1 as the password.

  2. For some weird reason, this just doesn’t work for me – I even tried to remove the whole Uninstall_Pwd-line and add a new one, but the password “1” is denied.
