Norton AntiVirus 2010 defends your PC against viruses, spyware, bots, worms, and more without slowing you down or getting in your way. Intelligence-driven technology identifies and targets only files at risk, for faster, less frequent scans. Vulnerability Protection prevents threats from exploiting security holes in your PC's software. 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. Plus, unlike other antivirus solutions, Norton AntiVirus provides easy-to-understand threat explanations and information about CPU and memory resource usage to help you prevent future infections and keep your PC running fast.
