I keep getting emails in duplicate - one from the college, and then immediately afterwards one from verizon.net, both from the same sender. The one from Verizon.net has infallibly been cleaned of this worm: WORM_KLEZ.H

The ones from the college have not been exorcized... The worm is apparently already within the walls of the college security, creating addresses from our server to spread the infection. If you get any mail from verizon.net or hivolda.no, from a sender you don't recognize, beware. I hope the fact that I am not in a habit of opening spam or attachment I am not familiar with should keep me safe, but I can't guarantee the pristinity of my mailbox if the college server has been comprimised.
