Uninstall Trend Micro without password

Simply enter regedit, browse to HKLM\Software\Trend Micro\PC-cillinNTCorp\Misc.

Change the key “allow uninstall” to be 1, and you will no longer be prompted for a password.

I performed this with trend micro unloaded. In order to do this, you may need to set the unload password to 70 in ofcscan.ini in the Program Files directory for Trend Micro and enter 1 as the password when prompted during unload. Unload may not be required, however, so try without first. If you search for “uninst” in notepad when entering this new value, you can also enable uninstall in the INI. This had no effect for me, but may have contributed to the end solution.
