Norton AntiVirus for Internet Email Gateways works at your SMTP gateway, automatically intercepting and destroying viruses that may be hidden in email attachments. You can even set separate scanning policies for incoming and outgoing files, and for a virtually unlimited number of file types. The utility scans compressed and encoded files and can be administered from any location via a convenient HTML interface, with minimal impact on network performance. And Norton's LiveUpdate means that free virus definition updates are available online at the click of a mouse.
