Thanks everyone for the suggestions. I plan on trying this again over the w/e and will let you know the outcome.
Yep, that restore point saved me!
I did thorough scans beforehand with all the anti-virus, anti-malware, etc. programs I have, including a boot scan with avast. I'll start from scratch this w/e, make sure everything is off, and set another restore point. I know the computer sets these, but I like to set my own right before I do something like this.

Sidebar: Another sorta related question fueled only by my incessant curiosity---is it possible to update Windows through Firefox rather than IE? When I go to Windows site to update, it says I have to be on IE to do it. I have both, so it's not an issue other than, as I said, my curiosity!
