I would suggest monitoring with a sniffer such as ethereal. That is what I used to discover sdbot on our network. This
will tell you what address are generating traffic and what port there trying to reach.

Subject: network worm
in the past days our network was stressed from a lot of network worm (not find from local antivirus, already up to
date) with a stop of the traffic caused from a lots of arp request. The last one was the WORM_SDBOT.ACJ a worm that
propagates itself using network shares and a worm that trend micro (up to
date) was unable to find, causing the saturation of the network switches and the related stop of all the work. The
question is: "is there the possibility to setup an instrument (even linux based) to sniff the network traffic with
capabilities to find worm?". We have already a linux based tool for network monitoring, this tool is useful to isolate
host with a lots of ARP request (typical of the worm), but this tool can't point us to which worm is doing the traffic.
Thanks a lot
