Ugh, I downloaded the program, but when I put it to scan, after a while (I left it alone, thinking it would take a long time), I came back to see the blue screen of death ("Physical dump memory, etc etc").
I'm hoping there's a solution that can bypass using that program again -- just because I hate that screen. Thankfully, I rebooted and am using the same computer to make this post, so all is not lost. Yet.
