Seems sort of like the old DAM suffix - but instead of being damaged, these files were modified to act as droppers. Not actual viral infection, but perhaps infection in the furtherance of the worm. Another write-up I saw mentioned infection of portable executable files, again not with copies of itself like a virus, but rather to add dropper functionality. So, I'm guessing it could be polymorphic in the way it infects PEs and the symptoms David Kaye experienced was because some were being missed by the current definitions supplied for the AV tools he used. Either that, or there is something *new* about the one he had.
