When you enable GAV, the SMTP, HTTP,or TCP proxy looks at e-mail messages and web traffic, and removes any viruses it finds. (The GAV configurationof a TCP policy is in an HTTP proxy action referenced by the TCP proxy action that matches it.)NoteIf your organization does not use an e-mail server protected by the Firebox, Gateway AntiVirus does notprotect against e-mail viruses.If you enable Gateway AntiVirus with the SMTP proxy, it finds viruses encoded with frequently used e-mail attachment methods. These include base64, binary, 7-bit, and 8-bit encoding. Gateway AntiVirusdoes not find viruses in unencoded or binhex-encoded messages; the Firebox® strips these types ofmessages.If you enable Gateway AntiVirus with the HTTP proxy, it finds viruses in web pages that users try todownload. If a virus is found, the user’s connection is dropped. (GAV does not give a notification aboutwhy the connection was dropped.)308 WatchGuard System Manager
