I had this problem recently. Our offsite guy who installed it would not tell me the password (I figure it must be something really nutty) even though he does not work for us and does not own our computers. The laptop would not start except in safe mode w/o networking. I had tried many suggestions that I found, but for whatever reason, none of them worked. I downloaded a thing called the revo uninstaller from download.com. The revo uninstaller does not care about passwords and wiped out every little bit of TM.

I wanted to uninstall Trend Micro from a laptop which nobody had the password for, I successfully uninstalled Trend with the help from Dan LaMoreaux posted instruction on May 20th, 2008 12:58 PM.

Thanks Dan!

Simply change the value of HKLM_SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc.\AllowUninstall from 0 to 1

This worked perfectly, I am albe to script this and make the change to several computers.

THANK YOU!! Renaming the sub directory worked perfect.

1. Start RegEdit
2. Browse to HKEY_LOCAL_MACHINE\Software\Trend Micro\PC-Cillin
3. Rename key (I had version 14, so in my case I renamed it to a14)
4. Go into Control Panel and then run the uninstaller from Add/Remove Programs

Manually Uninstall Trend Micro Internet Security Pro and Trend Micro Internet Security 2008 with TISSuprt.exe

Close the main console for Trend Micro Internet Security if it’s opened.
Open Windows Explorer and navigate to the following folder:
C:\Program Files\Trend Micro\Internet Security\

Note that change the drive letter if Trend Micro is installed at another partition accordingly.

Double-click to run the TISSuprt.exe file, which has a red and white lifesaver icon.
The Trend Micro Diagnostic Toolkit window will appear. Click on the Uninstall tab.

Click on the Uninstall button.
Click on the UnInstall button again when asked if you want to continue with the uninstallation.

Note: If a message appears asking you to delete quarantined files, click Yes to proceed with the uninstallation.

A message appears when the uninstallation is complete. Click Yes to restart your computer.
