I am trying to help a Network Admin with cleaning virus (s) off a Windows 2003 Server. We know that one of the 65 computers is pushing out email spam, (Our business has been blacklisted) We have Trend Micro, but it's not really helping with locating which machine is infected. I wanted to ask if anyone knew of any tool (free or otherwise) that we could use on the network to help pin-point which machine is sending out the junk. Sorry if I'm missing any technical info, I will try to do what I can. Thanks for any help.. We're starting to pull hair out..
