OK, back up and certified clean, for what that's worth - it was W97M.class, which had infected my 2001 catalog creation file, and cleaning it turned it into gibberish. Guess no work this weekend, quelle dommage. It had also gotten to my normal.dot and my recycle bin, but apparently the worst thing it does is occasionally tell a Word user they're a jerk, or mysteriously open and close (but not alter) Word files. Can't really argue with it, I guess, since I only use Microsoft if I have to...
