New variant of MyDoom?

[Bob Jones]

Hey all... we have recieved a few messages with .zip attachments that
aren't caught by the latest McAfee which seem to be a new variang of
MyDoom.  All the virus company's websites are very slow right now so I'm
assuming this is hitting a lot of people.  We have temporarily started
blocking .zip attachments until we get definitions that can recognize
it.  Just a heads up...
