Thank you for your input and assistance, spybotsandra. This is distressing news, but I am glad to have an official word.

Rootalyzer found nothing when I ran it, and I was not given the option to pack suspicious files, probably because the deep scan was blank at the end of the run. I find that a little peculiar, because I know that there are some SecuROM related files that RootkitRevealer usually finds when I run it (Harmless and needed for some games, but still they com up during those scans).

Unfortunately I didn't have time to run a gmer scan this morning. I will do so post-haste when I have the time in a few hours.
