desktops. New signatures are created and added to the database by a combination of 
SonicWALL’s SonicAlert Team, third-party virus analysts, open source developers and other 
sources.

SonicWALL GAV can be configured to protect against internal threats as well as those 
originating outside the network. It operates over a multitude of protocols including SMTP, 
POP3, IMAP, HTTP, FTP, NetBIOS, instant messaging and peer-to-peer applications and 
dozens of other stream-based protocols, to provide administrators with comprehensive network 
threat prevention and control. Because files containing malicious code and viruses can also be 
compressed and therefore inaccessible to conventional anti-virus solutions, SonicWALL GAV 
integrates advanced decompression technology that automatically decompresses and scans 
files on a per packet basis.

SonicWALL GAV delivers comprehensive, multi-layered anti-virus protection for networks at the 
desktop, the network, and at remote sites. SonicWALL GAV enforces anti-virus policies at the 
gateway to ensure all users have the latest updates and monitors files as they come into the 
network.
