Most anti-virus products rely primarily on signatures to stop viruses. These signatures are based on known viruses. Relying solely on this method leaves a dangerous window between the time a virus first appears and the time a signature is developed and deployed. At the moment the outbreak occurs - "Time Zero" - a virus has the opportunity to do significant damage to your computer system. Every passing minute until a signature arrives is enough time for a virus to multiply exponentially and compromise another portion of your network.
SonicWall's breakthrough Time Zero Anti-Virus Technology provides predictive virus defense complemented with responsive techniques to stop viruses as soon as they emerge. This technology is complemented with leading anti-virus engine from McAfee. With SonicWall Time Zero Virus Technology, e-mails potentially containing new viruses are identified and safely quarantined, while known viruses are blocked by virus signatures.
