But on this public terminal, even if I had some tools I could deobfuscate it with, I don't know enough about windows trojan programming to ensure I didn't trigger the damn thing just by trying to read it.

Thanks for clearing it up (somewhat). I was wondering if I should report them to their ISP for it, but hell, no harm no foul, right? (Translates as: I don't feel like spending the next three weeks trying to explain to level 1 support that this thing was a nastygram.)
