Norton AntiVirus defends your PC against detected viruses, spyware, bots, worms, and more while minimising the performance impact or getting in your way. The improved Norton Protection System features multi-layered protection technologies that work together to proactively block attacks and detect and remove threats before they can harm your PC.

Pulse Updates every 5 to 15 minutes and real-time online security checks help ensure continuous, up-to-the-minute protection against the latest threats. New SONAR 2 (Symantec Online Network for Advanced Response) technology monitors your PC for suspicious behavior to help detect and eliminate the latest breaking threats.

Intrusion Protection defends your PC from web-based attacks so you can surf with confidence. And new Vulnerability Protection blocks security holes in your PC’s operating system, applications, browsers, and browser plug-ins to prevent hackers from exploiting them.

The new Norton Performance System ensures strong protection that won’t swallow up system resources and will minimise performance impact. Norton AntiVirus offers the fastest install time, the fastest boot time and the lowest memory requirements of any antivirus and antispyware solution. Norton Insight technology identifies and targets only files at risk, for less frequent, shorter scans and the fastest scan speeds in the industry.

In addition to usual anti-virus protection, Norton AntiVirus provides easy-to-understand threat and performance information to help you prevent future infections and keep your PC running fast. Plus, only Norton AntiVirus is backed by Symantec Security Response, which provides comprehensive, global, Internet security expertise to guard against today's complex threats.

The Norton AntiVirus application scans faster and uses less memory than any other antivirus product on the market.
