Configuring SonicWALL Network Anti-Virus SonicWALL Network Anti-Virus is a distributed, gateway-enforced solution that ensures always-on, always-updated anti-virus software for every client on your network. The SonicWALL constantly monitors the version of the virus definition file and automatically triggers download and installation of new virus definition files to each user’s computer. In addition, the SonicWALL restricts each user’s access to the Internet until they are protected, therefore acting as an automatic enforcer of the company’s virus protection policy. This new approach ensures the most current version of the virus definition file is installed and active on each PC on the network, preventing a rogue user from disabling the virus protection and potentially exposing the entire organization to an outbreak. Most importantly, SonicWALL Network Anti-Virus offloads the costly and time-consuming burden of maintaining and updating anti-virus software across the entire network. SonicWALL Network Anti-Virus also includes Network Anti-Virus Email Filter to selectively manage inbound Email attachments as they pass through the SonicWALL to control the flow of executable files, scripts, and applications into your network.
