No kidding. I had to download a program called "DelInvFile" (which is a trial copy and only removes 3 files total) to get rid of the Securom files. It was fairly easy though. Google ftw!
Oh and mojoman to answer your other question about reinstallation - You can install it again but you do need an activated and installed copy of Windows XP or Vista (or possibly Windows 7) to do the installation. I don't know if the Vista Upgrade trick works or not.
I didn't format the partition or anything, and the installation was on the drive before it "cleaned" all of the old software off. You will have all files from your User and Program Files folders on the drive still after installation (though they will be stored in Windows.old). They can be easily removed though and as far as I can tell, the clean install worked perfectly fine.
