Ah yes- Frobnication is definitely not for the faint of heart; you're lucky to have made it out of that link alive... :mrgreen:

I agree about the "stubborn programs" bit; if it were my machine, I'd be digging around in it until I found out exactly what those files are, malicious or not. Unfortunately, since I'm not sitting in front of your computer I can't offer you any more help along those lines.


Oh, and as for this:

Accidentally? I've never seen it happen personally, but that certainly doesn't mean it couldn't. The only circumstance I can think of which might be slightly related would be with infected files which an AV program has quarantined, but that doesn't seem to apply here.
