gossamer

Gossamer is a little red fuzzy monster that loves gobbling up computer viruses. He hangs out on computer networks and fishes out viruses from emails. Whenever he finds one, he lets everyone know about it by writing up a ticket that says what the virus is and how to get rid of it. Of course, Gossamer also sends an email to both the sender and receiver to make sure they know that there's a nasty virus going around!

Gossamer is actually built on top of a pack sniffer called TCPick - a little application that lets you listen in on network traffic. Gossamer listens specifically for email network traffic. When an email comes through, he checks if there are any attachments and if there are, he scans them.... and let you know the results!
