This is horrible. I think usually they can't get the money back, but sometimes they can, especially if you take care of this TODAY. Put "urgent" in the subject line when you e-mail stars. See if you can get a security person on the phone, actually.

What can we do to make sure this doesn't happen, other than have a good virus scan? This is the main reason to keep most of your bankroll in a savings account IMO. Keep your chin up man, if the worst happens, you made 13K once and you can do it again.
