I have local sensor that sniffs lan nic of the firewall. I see a couple of

        I've seen it a few times being a false alarm: reports about Nimda from
security sites, for example. The one alert that is a false alarm only on rare
times is the "readme.eml autoload attempt", which matches the javascript code
that sends the infected file. It can be a false alarm too, but in my
experience it has been so very few times.

        Anyway, your best bet is to check the traffic with tcpdump or ethereal
(if you captured it in tcpdump format, what I'd strongly recommend :-)), and
see what the payload is.
