I would like to know why Norton 360 dont have some of these as nis or nav 2011. Norton 360 is all in one. What would be better to use. I had thought about using norton 2011 but has automatically renewed.

Thanks to Symantec for bringing out this product.All Symantec products including Norton are undoubtedly the best.I suggest everyone to use Norton products.These new features in 2011 will give a new challenge to cybercriminals. The important thing is that Norton is improving its products dramatically year by year and thats so great from them.Now I am eagerly waiting for the Norton 360 new version.

Norton Internet Security 2011 does outshine protection competition in all areas. Norton is the leader in security for computers in my book. I have used NIS for about 10 years now, and it gets better and better every year. Keep up the good work Symantec.

You should be able to turn off auto renewal in mynortonaccount.. I would contact customer support if it just auto renewed if you want to use NIS 2011. NIS is more tweakable than N360 is and the newer engines come out sooner for NIS than for N360.

The firewall scans for Internet-enabled applications and creates access rules during installation based on a knowledge base maintained by Symantec. In PC Magazine testing, the installation took 24 minutes to complete on a 750 MHz Pentium III with 92 Internet-enabled applications. Using the firewall, users could determine whether to accept cookies, Java applets, and ActiveX controls on a global or per-site basis. A new feature, Intrusion Detection with AutoBlock, could detect port scans and block further intrusion attempts. The program provides notifications for intrusion attempts, reporting the severity level and providing access to threat details. Alternatively, the firewall could put the computer in stealth, essentially hiding the system. Users could configure the security level, managing the number of notifications. Testing conducted by PC Magazine using Shields Up and Symantec's Security Check found that the firewall successfully stealthed all ports, hiding the computer from view. A leak test was conducted to see the firewall's ability to detect outbound connections. Each attempt was detected and the suite offered to block the attempts.[18]

Running a full scan compiled a list of Internet-enabled applications. Users set permissions or accepted Norton's defaults. The firewall detected and blocked port scans and logged intrusion attempts. This version did not trace attackers. To ensure rogue programs could not masquerade as trustworthy applications, Norton verifies programs against a list of digital signatures for known programs. Update Tracker warned users when hackers attempted to gain access. The firewall blocked all access attempts from Shields Up and Port Checker. This version included a wizard to simplify firewall setup to accommodate multiple computers sharing an Internet connection. With this release, Norton could prevent specified personal information from access by a compatible instant messenger client, e-mail, and websites. Ad-blocking included the Ad Trashcan, where users could place ads that escaped ad-filtering.[24]

Symantec introduced Version 2005 on August 17, 2004. This version was sometimes referred to with the tagline of AntiSpyware Edition, since spyware detection was integrated with Norton and was by default enabled. Found threats were listed, separating the ones already dealt with and the ones requiring user interaction. More detailed information was provided through a link to Symantec's website. However, PC Pro and PC Magazine noted lengthy scan times. A full scan took 24 minutes to over half an hour, respectively. In PC Pro testing, Norton detected 61 percent of the spyware samples, compared to an average of 68 percent for all the tested products. Removal rates were above average, 72 percent versus the average of 68 percent. Norton blocked reinstallation with a score of 48 percent, compared to the group average of 43 percent. Overall, Norton ranked fifth among the tested products.[36] In PC Magazine testing, Norton installed slowly on infected systems and failed to install on one altogether. Contacting Symantec did not resolve the issue.[37]

Anti-phishing integrated with Internet Explorer. It analyzes sites, examining the website's URL, title, form, page layout, visible text and links, and uses a blacklist to detect phishing sites. Users were blocked access from suspected phishing sites, however were presented an option to continue. In PC Magazine testing, the feature blocked 22 of 24 phishing sites, while Internet Explorer 7 recognized 17 of the 24 sites. In PC Pro testing, the feature successfully blocked access to every phishing site it was tested against.[43] Spam filtering no longer included a language feature, Symantec claimed it was less useful with current spam and created false positives. Tested against 1,500 messages by PC Magazine, Norton let over half of the spam into the inbox. Five percent of valid mail were marked as spam. This version utilized Symantec's Veritas VxMS technology to better identify rootkits. VxMS allowed Norton to find inconsistencies among files within directories and files at the volume level. A startup application manager allowed users to prevent applications from launching at login. This release dropped support for Windows 2000 and was compatible with Windows Vista upon its release with an update.[44][45][46]

PC Magazine found that the firewall put all ports in stealth mode. The firewall blocked ten of 12 leak tests, used to see if malware could evade the firewall's control of network traffic. Previous versions did not identify the tests because none carried a malicious payload. Another test was conducted using Core Impact, which successfully exploited one vulnerability on the test computer. However, other components of Norton stopped the exploit from causing harm. The other attempts were unsuccessful either because the system was invulnerable or Norton's Intrusion Prevention System stopped it. Attempts to disable the firewall were unsuccessful by PC Magazine.[47] On the contrary, PC Pro identified 15 open ports on a computer with Norton installed.[49]
