This procedure comes in handy if you have forgotten the unlock/uninstall password for your installation of Trend Micro OfficeScan. I have also had to use similar procedures for migration projects where it was desired to have a different AntiVirus installation upon migration.
The password for the Trend Micro OfficeScan is stored in a file called Ofcscan.ini. You could easily search your hard drive for this file but it is usually located in C:\WINDOWS or C:\Program Files\Trend.
Open the Ofcscan.ini file and locate the section labeled [INI_CLIENT_SECTION]. Once you’ve gotten down to the appropriate section in the file, look for the Uninstall_Pwd= entry. You will likely see a long string of characters that represent the password, simply change that to 70 so that your resulting entry will look something like: Uninstall_Pwd=70. Save the file and now you can resume your unlocking or uninstalling. The new password that you’ve set will be 1.
