I'm seeing some machines with literally thousands and thousands of these
files filling up their HDs.  Besides in the root director I'm seeing
people with them in the scripts directory as well.  Another thing
interesting to note, but not surprising, is that a lot of the hosts I'm
seeing infected with this new worm are machiens that still have teh Code
Red II trojans sitting on them.  This could really cause some headaches.

Regards,

Stan
