You can have the two copies I just got. Cleared the access.db (stops spam
and such) for only several hours, and planet.nl and sent me two copies.
Win32.Swen is dying due to several reasons I belive: Free email carries
(usually a large infection vector for mass-mailers) such as Hotmail now
auto-block Swen; Win32.Swen's bogus "Patch" screen has appeared on many AV
sites and else where- people know what Swen looks like, so even if they
know nothing else, they automatically think "virus: bad".

But sadly, time and time again they do, they open attachments, execute
things like "readme.exe". Or fall prey to tricks like was utilized in the
last virus "myphoto.jpg .exe" (notice
spaces, that's still an executable).
Now Win32.MyDoom.B is a strange case. I've yet to receive this virus in
the mail like was intended. If you've followed the "Full-Disclosure"
lists, you'll see that varient B has become somewhat of a collector's
item- something to obtain and attempt to "overcome" with home-analysis &
disassembly. I was amazed at the number of self-proclaimed "researchers".
So yes, MyDoom.B is spreading- not like the author pictured it would!

To my knowlege, no virus has yet to sucessfully receive instructions from
another virus designed to allow that virus to better spread. Viruses, for
all their mystery, are only programs, not living, reasoning things. While
it may be technically possible for a virus to search out its environment
and interact with another virus already installed (or even rootkit?)
there to further its own infections, this approach to replication would
involve significate amounts of AI, and in doing so would result in a very
large and unwieldy virus better suited for POC code than an actual,
in-the-wild intended virus.
