Fedix.A??

I have just received a notification from my Norman virus control software saying that it removed the worm called Fedix.A. For the live of me I can not a description anywhere on the internet regarding this worm, I even looked at the Norman.com site. The filesthat were infected was a .dll file in a program that we have been running for years now. The other infected file was in a Trojan Program that I have been using for the last month now. Can anyone help out?
