| 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.


Maybe it is like the Virut in that it modified HTML files in a way that when viewed it 
could cause you to download and re-infect the computer.
