That's what the net admin was telling me when I mentioned one of his 
branch bank offices had Sobig-F. Apparently they all run A/V and I think 
he said his mail server does as well. Unfortunately, they still allow 
executables in.

The problem is the false sense of security while using anti-virus
products. For having a working signature, somebody has to be hit first
and submit the virus to the AV vendor. This requires a certain time,
which leads - in case of the latest womr occurences which appear to be
pretty aggressive - to a certain amount of infections that happen before
there are signatures available. And then, the update still has to be
downloaded to the AV scanning software which extends the time window
being unprotected against a certain worm or virus variant.

So, the virus and worm authors are always one step ahead. This is by
design of the AV concept.

Better put the wasted cash and time into the design of better systems,
which brings the software developers this critical one step in the lead.

Due to what obscure reason does a mail user agent have to execute
interpreted code and do unasked things to mail attachments, nowadays?
