byon's blog – my daily rant!

I have been searching everywhere on removing Trend Micro OfficeScan pre-installed on laptops bought in SMU matriculation. I’ve successfully uninstalled it, here’s the solution if anybody is interested.

Necessary steps:
#1. Change Registry Keys
HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc
- AllowUninstall value to 1
- NoPwdProtect value to 1

#2. Disconnect from the Internet / Disable Wireless/LAN Adapter

#3. Modify certain values in C:\Program Files\Trend Micro\OfficeScan Client\OfcScan.ini

- Search for [INI_CLIENT_SECTION]
- Change the Keys to these Values
Uninstall_Pwd=70
Client_Allow_Uninstall=1
Client_Allow_Unload=1

Save Ofcscan.ini, Uninstall. It didn’t prompt me for a password, but if it did, enter “1″.
* if it doesnt work, restart the laptop/computer, disable internet connection, then uninstall.

I’ve installed ESET NOD32 over this.
Cheers.
