One of the best security software nowadays; light, unobtrusive, great phishing detection, superb zero day protection with reputation info (Norton Insight), Sonar (behavior blocker), modern firewall, anti-bot that works on network level, good generic signatures and much more.
In my opinion only Kaspersky and Emsisoft are on the same level of protection when we talk about "traditional" security software, they are only behind things like Appguard/Sandboxie/Full virtualization.
