I want this feature to be included in Norton Internet Security, Norton Antivirus, and Norton 360. This feature is a Real-time Behavior-based Protection. It protects computers from zero-day attacks. Since Norton Internet Security 2010, Norton Antivirus 2010, and Norton 360 v.4.0 rely on virus definitions to detect and remove malware. The new real-time protection will protect users from new and unknown malware. While this malware has been blocked, then submit the new malware information to Symantec to create new virus definitions to be added into the Norton security products.
Also I have extra information for Symantec to research on. Here are the website links.
