GateWall Antispam features two integrated antivirus modules from Kaspersky Lab and Panda Security. Both these modules are used to scan mail traffic for viruses. You can configure the modules on the corresponding page of the administrator console. Prior to enabling an antivirus module, launch virus definition update and wait for the update process to complete. The antivirus page indicates if your virus definitions are up to date. You can also use this page to schedule virus definition updates.
