I recieved this today as part of an email

Antigen for Exchange removed anabnr2.gif since it was found to match the FILE FILTER= *.gif file filter. The file anabnr2.gif has been quarantined. To have the anabnr2.gif delivered from quarantine please forward the message with the quarantine attachment to the DEP Helpdesk and we will deliver it if it is not infected.

I think the world is going mad, since when was a gif file a virus!!!
