After panicking Saturday night over the whole, "omg, I've killed my computer" thing, I discovered that I was fast enough, thanks to Zone Alarm's version of a panic button, to keep it from infecting my computer. Don't know if it was just that that saved me or a combo of patches, anti-virus protection, the firewall, and my quick shut down. I've managed to get through it without a reformat.

All scans now come back totally clean. I've run it through both NAV and the online free version of Kaspersky. That should be the end of that problem.
