Uninstalling Trend micro OfficeScan Client 10

This SW came installed on my Inspiron 1720.  I cannot seem to uninstall it... The uninstall asks me for a password, which I do not have, and have never set up.

I have tried various methods seen on the internet (edit OFCSCAN.ini, edit registry) with no luck... this is ridiculous - I should not have to do all this just to uninstall a program that I didn't want in the first place...

There are links to info on how to uninstall various "For Dell users" versions of this product, but not for version 10 (they list 12 and 14).  There are references to using the Trend Micro toolkit, but of course, that is not installed on my computer...

I'd sure appreciate any advice anyone might have... this is very frustrating...
