Editors' Review

The bottom line: Norton Internet Security 2011 maintains its recent strong performance record and introduces some useful new features in the latest version, making it one of the top Internet security suites available.

Review:

Editors' note: Portions of this review are based on CNET's review for Norton Internet Security 2010.

Over the past few years, Symantec has completed a course reversal for its Norton consumer Internet security suites. The massive package of security tools works better than it ever has before, with an impressive set of features, some useful new tools including the free Power Eraser, and third-party security efficacy benchmarks that are nothing short of remarkable. Meanwhile, CNET Labs' performance benchmarks indicate that though Norton doesn't leave the smallest footprint on your system, users should see a minimal impact overall.

Installation
For the second year in a row, Norton's former sluggish beast now offers a smooth and fast installation operation. Once you run the installer, the program is ready to operate in about a minute--impressively fast, and doubly so considering past performance. The installation process is also the first time that you will interact with Quorum, Norton's behavior-based detection engine. You'll be asked to participate by sending anonymous data to Symantec's cloud. Opting out of the data submission, according to Symantec, will not affect your security.

Running the trial of Norton also requires registering the program. Like many programs, Norton used to force open your default browser and take you to the company's registration Web site. One of the new features in Norton Internet Security 2011 is that the program comes with a Web interface for your desktop. Users first encounter this when registering, but it pops up in regular program usage as well, keeping users from being forced to open their browsers to manage certain Web-based features. Uninstalling the software left about 10 Registry entries behind, but no other traces were detectable. Overall, Norton's installation experience was fast and hassle-free, with a minimum of configuration options--but the ones that did come up appeared necessary.

Interface
Norton Internet Security 2011 contains some changes to its interface, although the design is heavily reminiscent of the previous version. It keeps the dark theme, punctuated by yellow text, but moves the large graphic security status indicator from the main interface window up to the taskbar and system tray icons. As long as you don't mind the lack of empty space in the interface, it works quite well.

Security controls have been condensed into three sections in the main window: computer protection, network protection, and Web protection. To the right of each category is a series of controls, which by default are all active. Click on one, and its gold indicator moves to the right and changes color to red to show that it's been deactivated. A window then pops up, asking for how long you'd like to deactivate the service. This cleverly resembles Windows 7's "postpone reboot" option for system updates, so even novice users should find it recognizable. Click on the name of a control, such as Antivirus, and a pop-up appears summarizing what the feature does.

Below each category are several controls specific to that area of protection. So, under computer protection, there are text buttons for instantly initiating a scan, for forcing a virus database update, for accessing your History or Quarantine, and for viewing Application Ratings.

At the bottom of the interface is a wide, short map of the world covered with blinking yellow dots. Each one, according to Symantec, represents a threat to one of its users that has been successfully blocked. The visual is cute, but completely irrelevant to your personal safety. More interesting is that below the map there are a series of mobile-app-style buttons. From there you can access Norton Online Family, Norton Online Backup, and Norton Safe Web without having to jump into your browser.

Features and support
There aren't many new features in Norton Internet Security 2011, or even new major features. What's changed is in how Norton presents its features--across the board the program is easier to navigate--and how the features operate.

The reputation-based security checks where your programs were installed from and when they were installed, and compares that data against the 58 million users participating in the crowd-sourced Norton Community Watch to see if any of your programs should be red-flagged. Norton's System Insight component has been bumped up to version 2.0, which is the proprietary internal network that warns you when your programs unnecessarily hog system resources. This gives some extra heft to the system performance map, where you can click on any spike and see what caused it.

The second iteration of Download Insight applies the same reputation-based logic to new downloads, and the third version of Norton SONAR (Symantec Online Network for Automatic Response) looks for suspicious software behavior and automatically chooses protective actions. You can toggle how aggressive SONAR is in the Settings window.

Along with the quick scan, full system scan, and the custom scan for viruses and malware, you can now have Norton scan your Facebook wall for malicious links. There's also on-demand reputation-based quick scans, full scans, and custom scans for users who want Norton to immediately scan their installed programs. After completing a scan, Norton provides users with a summary report. More-detailed information, including scan duration and a deeper dive into threats discovered, can be read under the History option from the main window. There's also a link so that you can follow in case you believe that Norton missed something in its scan, although as the reputation-based protection matures, the need for on-demand scanning becomes less of an issue when compared with the "always-on" protection offered here.

The bootable recovery tool isn't new, but it now comes with a feature that automatically creates a CD, DVD, or USB-based bootable device. The USB component is especially important on optical-drive free systems such as Netbooks.

Norton continues to dabble in free security offerings, including the Norton Online Family parental controls, the "lite" version of Norton Safe Web, and the new Norton Power Eraser. Power Eraser is a new tool that will aggressively clean your computer of fake antivirus programs and other malware that prevents legitimate security tools from being installed.

As with the rest of the program, the support options have been streamlined behind a drop-down menu in the top right of the interface. Help opens local support, Tutorials takes users to a Web site with extensive how-tos, and the "Get Support" link accesses the breadth of Norton's customer support in a new window. Here, users can chat with tech support 24-7, explore the user manual, and check out the Norton FAQ and knowledge base. Phone support is also available, although Symantec takes part of the trend to make phone support harder to access by funneling users to online resources.

Performance
Norton's fast installation and comprehensive feature set would be useless without solid performance, and Norton Internet Security 2011 delivers extremely high third-party efficacy benchmarks and strong performance benchmarks.

In a real-world test, Norton 2011 completed a Quick Scan in 47 seconds; the Full Scan took 1 hour 47 minutes and 13 seconds. CNET Labs' benchmarks found both Norton Internet Security 2011 and Norton AntiVirus 2011 to have performed well, although not as strong as some of its competitors. NIS 2011 slowed down the Labs' computer boot time by about 6.5 seconds, whereas NAV 2011 added a shocking 12.5 seconds.

However, Norton Internet Security had a very small impact on the computer's shutdown time, slowing it down only by half a second. Scan times for both were reasonably fast in the Labs, whereas the iTunes decoding test results were fast, too. The Microsoft Office and media multitasking benchmarks, on the other hand, were slower, with Norton AntiVirus marking the slowest result on the media multitasking test. The Cinebench test saw both Norton AntiVirus and Norton Internet Security come the closest to having the least significant impact on the test, leaving a mixed set of results overall. That being said, Norton AntiVirus clearly had a bigger effect in our Labs than Norton Internet Security.

In independent threat detection and removal tests, Norton is a top performer. Dennis Technology Labs, a member of the Anti-Malware Testing Standards Organisation (AMTSO), found in July 2010 that Norton Internet Security 2010 earned an overall protection score of 100 (PDF), tied with Trend Micro. The details of the test were just as impressive, with 40 out of 40 real-world threats defended against. By comparison, Trend Micro defended against 38 threats, but could only neutralize two. Norton also had only two false positive warnings during the test, and no false positives that blocked legitimate programs.

In the AV-Test.org test on Windows 7 from the second quarter of 2010, Norton Internet Security 2010 scored 16 out of 18, with a 5.5 out of 6 rating in Protection and Usability, and a 5 out of 6 rating in Repair. Norton, Kaspersky Internet Security 2010, and Panda Internet Security 2010 were the only suites to score that high.

Security program Boot time Shutdown time Scan time MS Office performance iTunes decoding Media multitasking Cinebench
Unprotected system 42.5 11.28 n/a 917 180 780 4,795
Norton AntiVirus 2011 55 13.6 892 1,045 198 948 4,780
Norton Internet Security 2011 48.91 11.78 890 1,028 199 861 4,780

*All tests measures in seconds, except for Cinebench. On the Cinebench test, the higher number is better.

The most recent AV-Comparatives.org tests showed more variance in results than other tests. In the On-Demand Comparative test from February 2010, Norton Internet Security 2010 scored in the highest category, Advanced+, with 10 other competitors. Norton was noted for having fast scan times and a low incidence of false positives, and for stopping 98.6 percent of threats it faced. In the Retrospective/Proactive test from May 2010, Norton did not do as well and only reached the score of Advanced. Eleven competitors detected more malware in the test than Norton did.

It's worth noting that there's some debate as to how useful the Retrospective/Proactive test is in a world where virus definition files become outdated hourly.

Following the path blazed by Norton 2009 and 2010, Norton continues to build a strong performance record based on excellent detection, fast scan times, and low false positives.

Conclusion
Symantec positions its premium security suite, Norton Internet Security 2011, as one of the best paid-license security suites available. The tighter integration of behavioral detection, the easier access to Web-based premium features, and the impressive benchmarks make Norton Internet Security 2011 a comprehensive, robust security option that users can put their trust in.

Pros

Norton's Detection rate is Astonishing, They have definitely improved on detection and have become No1 for Detecting the most viruses and removing them.

Cons

Although their detection is amazing the UI Is Ugly and it still uses a high amount of RAM and CPU But not as much as before which is a start...
its WAAAYYY over Priced

Summary

if you have a High Spec PC lets say with 2GB RAM then use it you wont have any Problems any lower and you WILL struggle as it pretty much uses 500MB of RAM, Its UI is not Great its Way over Priced and Updates are POOR, Apart from that Protection is Amazing
UI >3/10, Protection > 100/100 :] , Features >6/10, Price >5/10, Overall >6/10

"Warning!!!View people's ratings not CNET's editors $$!"

August 13, 2011  |  By gmoney007xxx

 |  Version: Norton Internet Security 2011 18.1.0.37

Pros

None too expensive you never get your refund for this junk you pay and you get to talk to a person you can NOT understand. Buy this junk if you want to get endless run around on the phone ripped off and your pc/laptop crushing all the time.

Cons

Very hard to remove from your PC/Laptop to me Norton is a Virus and/or malware once you try to delete it your PC?laptop will crush and you will have to insert your restore and recovery cd's into your PC/laptop and lose all your hard work!!!!

Summary

This is a company that pays to get their sorry software preinstall on PC/laptops because no one would buy it or try it otherwise because it sucks!!!! Best software are like Avast or others that many of us get by CHOICE!!!! Malwarebytes Anti-Malware with CCleaner, Smart Defrag by Advance SystemCare 4, Auslogics Boostspeed and/or Glary Utilities. And most are FREE!!!! Better than NORTON JUNK and FREE!!!!

"Xfinity offers similar Suite which is good"

August 12, 2011  |  By jscott418

 |  Version: Norton Internet Security 2011 18.1.0.37

Pros

Minimal annoyance factor, easy to install, low resource impact.

Cons

The Xfinity version installs Security Guard from Comcast/Xfinity which is too bad. A bit slow for full scan. Somewhat annoying that it installs toolbar without your approval.

Summary

Although this is a much improved Norton product over older ones. I have to say this is probably only for those users who a super paranoid about Malware. If you don't mind big brother watching you and your incredably careless about web sites you navigate too. Then I think if you have Comcast/Xfinity broadband this is a very good way to get a free security suite that is very good.

"It's alright... I guess..."

July 17, 2011  |  By leaktester_777

 |  Version: Norton Internet Security 2011 18.1.0.37

Pros

Great web protection, allows you to block certain IP addresses from connecting to you (which I love) and has several protection features.

Cons

While Norton is good, it does have it's share of problems that keep it from achieving 5 stars. An annoying thing is, when you turn off some of the shields (I don't recommend you do this) but the file shield still removes viruses anyway.

Summary

Norton is okay, but get the internet security or 360 suite. The antivirus itself is a bit overrated. People generally trust Symantec way too much. Always have a second opinion. Especially with this program.

Updated on Jul 17, 2011

Sorry, I meant when you turn off the file shield, it still removes malware.
