Correct.

Not.
Vesser (which a few AV companies have called Deadhat) was discovered
early in the weekend spreading via Mydoom.A-infected machiens (and
rpesumably it would also hit the occasional Mydoom,.B out there too).
What Gadi alerted on as Mydoom.C has been agreed following analysis by
AV industry experts to be sufficiently different in critical ways from
Mydoom to be put in a new family and will be called Doomjuice.A by most
AVs.

Correct, but irrelevant to this thread...
