Norton Internet Security
The 2007 version was released on September 12, 2006. 80 percent of the code was rewritten, with the goal of reducing high system resource utilization. A tabbed interface allows users to access the Norton Protection Center and the program settings without separate windows open. Symantec also extended its Veritas VxMS technology, enhancing rootkit detection. VxMS allows Norton to detect inconsistencies among files within directories and files at the volume level. Phishing detection was introduced in this release for Internet Explorer. Norton checks sites visited in Internet Explorer against a blacklist and analyzes sites' code. Other features include a exploit scanner which looks at system components commonly hosting vulnerabilities, such as Internet Explorer settings. Supplementing the scanner, real-time exploit protection blocks attackers from leveraging common browser and application vulnerabilities. When possible, Norton will fix issues found; otherwise the user is warned of the vulnerability. A startup application manager allows users to prevent applications from launching at login.
