Anti-Virusappliance by using SonicWALL’s IPS-Deep Packet Inspection v2.0 engine to inspect all traffic that traverses the SonicWALL gateway. Building on SonicWALL’s reassembly-free architecture, SonicWALL GAV inspects multiple application protocols, as well as generic TCP streams, and compressed traffic. Because SonicWALL GAV does not have to perform reassembly, there are no file-size limitations imposed by the scanning engine. Base64 decoding, ZIP, LHZ, and GZIP (LZ77) decompression are also performed on a single-pass, per-packet basis.matching downloaded or e-mailed files against an extensive and dynamically updated database of threat virus signatures. Virus attacks are caught and suppressed before they travel to 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.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.appliance by using SonicWALL’s IPS-Deep Packet Inspection v2.0 engine to inspect all traffic that traverses the SonicWALL gateway.

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. Inspection version 2.0) engine, which performs all scanning directly on the SonicWALL security appliance. SonicWALL GAV includes advanced decompression technology that can automatically decompress and scan files on a per packet basis to search for viruses and malware. The SonicWALL GAV engine can perform base64 decoding without ever reassembling the entire base64 encoded mail stream. Because SonicWALL's GAV does not have to perform reassembly, there are no file-size limitations imposed by the scanning engine. Base64 decoding and ZIP, LHZ, and GZIP (LZ77) decompression are also performed on a single-pass, per-packet basis.
Reassembly free virus scanning functionality of the SonicWALL GAV engine is inherited from the Deep Packet Inspection engine, which is capable of scanning streams without ever buffering any of the bytes within the stream.application protocols, as well as generic TCP streams, and compressed traffic. SonicWALL GAV protocol inspection is based on high performance state machines which are specific to each supported protocol.
SonicWALL GAV delivers protection by inspecting over the most common protocols used in today's networked environments, including SMTP, POP3, IMAP, HTTP, FTP, NetBIOS, instant messaging and peer-to-peer applications and dozens of other stream-based protocols. This closes potential backdoors that can be used to compromise the network while also improving employee productivity and conserving Internet bandwidth.

Restrict Transfer of packed executable files (UPX, FSG, etc.)- Disables the transfer of packed executable files.
Packers are utilities which compress and sometimes encrypt executables. Although there are legitimate applications for these, they are also sometimes used with the intent of obfuscation, so as to make the executables less detectable by anti-virus applications.
The packer adds a header that expands the file in memory, and then executes that file. SonicWALL Gateway Anti-Virus currently recognizes the most common packed formats: UPX, FSG, PKLite32, Petite, and ASPack. Additional formats are dynamically added along with SonicWALL GAV signature updates.Configure Gateway AV Settingsbutton at the bottom of the Gateway Anti-Virus Global Settingssection displays the Gateway AV Settingswindow, which allows you to configure clientless notification alerts and create a SonicWALL GAV exclusion list.GAV when a virus is detected in an e-mail or attachment, check the Disable SMTP Responsesbox.from an HTTP server.
