threats from leveraging vulnerabilities. The system was updated whenever a vulnerability was identified. Attempts to disable the firewall were unsuccessful; registry changes, process termination, and simulated mouse clicks all failed. Disabling Windows services had no effect on the firewall since it worked at the kernel driver level. This version automatically adjusted configuration for different networks based on the physical address of the gateway rather than IP addresses. In PC Magazine testing, Norton detected 15 of 16 spyware samples. 13 of the 16 were removed. Against eight commercial keyloggers, the suite removed all the samples. On a clean system, Norton blocked 14 of the 16 spyware samples from installing, and stopped seven of the eight keyloggers from installing. 2008 (15.x) The 2008 version was announced on August 28, 2007, adding support for Windows Vista 64-bit. New features included SONAR, Norton Identity Safe, and Browser Defender. SONAR monitored applications for malicious behavior. Identity Safe superseded the information filtering function; instead of blocking personal information from leaving the computer, it stored personal information to fill webforms. It was password protected and checked a website's authenticity before filling any forms. Browser Defender inspected and blocked suspicious API calls, intended to stop drive-by downloads. Network Map identified networked computers with Norton Internet Security 2008 installed. Remote monitoring allowed checking the status of other installations on different computers; problems were identified with a red "X" icon. Using the feature, users could control traffic between computers. It warned users if they were using an unencrypted wireless network. The startup application manager and advertisement blocking features were dropped from this release. Information filtering, although superseded by Identity Safe in the suite, was available separately. It could be used in conjunction with Identity Safe. Phishing protection now integrated with Mozilla Firefox. Testing by PC Magazine found that Norton blocked 94 percent of phishing sites, compared to 83 percent for Internet Explorer 7 and 77 percent for Firefox 2. CNET identified an issue with the feature: when anti-phishing was disabled, Identity Safe still offered to automatically submit personal information to websites, including phishing sites. Symantec declined to call it a "flaw", stating it was recommended to use Identity Safe with anti-phishing enabled. Alternatively, Identity Safe could be used with Firefox and Internet Explorer's built-in anti-phishing capability. PC Magazine found that the firewall put all ports in stealth mode. The firewall blocked ten of 12 leak tests, used to see if
