The bad: Despite dramatic performance improvements during the past two years, Norton still doesn't leave the smallest footprint on your CPU, and new efficacy results show that while it continues to be in the top five apps at detecting malicious software, it still doesn't have the highest rate of detection.
The bottom line: Norton Internet Security 2010 builds on the immense progress it made in last year's version, maintaining a low system profile while strengthening its security framework. It's not perfect, but even Symantec's detractors should check it out.
Review:
Dramatic improvements to its Norton suite during the past two years indicate that Symantec has been listening to the needs and complaints of its customers. The company's strong and surprising changes to Norton's impact on system performance that it introduced last year are maintained in this new version, and a new behavioral detection engine called Quorum shows that Symantec can juggle performance and protection.

Dramatic improvements to its Norton suite during the past two years indicate that Symantec has been listening to the needs and complaints of its customers. The company's strong and surprising changes to Norton's impact on system performance that it introduced last year are maintained in this new version, and a new behavioral detection engine called Quorum shows that Symantec can juggle performance and protection.
Quorum incorporates behavioral detection with Norton Insight, a program-reputation engine introduced in the 2009 version of Norton. The purpose of these features, according to Symantec, is to respond faster to mutating threats, while also watching for hibernating infections that pose a potential, but not immediate threat. In the 2010 version, Insight has been split to address four main areas of concern: Download Insight for in-progress program downloads, System Insight for diagnosing system slowdowns, File Insight for file analysis, and Threat Insight for digging deeper into threat origins. Also included is a new enterprise-level antispam algorithm that, according to Symantec, shouldn't require any "training" to use. These features were acquired by Symantec with its purchase of Brightmail more than five years ago. Norton Internet Security also includes OnlineFamily.Norton, Symantec's new parental control system, and Norton SafeWeb, which is a search results and e-commerce rating component.

Full efficacy analysis isn't yet available for Norton Internet Security 2010, but last year's version scored better-than-average results, and what is available for the new release indicates that it will score similarly.
Installation
Former users of Norton should try installing this latest version, if only to see that this former sluggish beast now offers a smooth and fast operation. Once you run the installer, the program is ready to operate in about a minute--impressively fast, considering its past performance. The installation process is also the first time that you will interact with Quorum, the new 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 free registration at the Symantec Web site--you can't download the installer without it. 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 and features
Robust and well designed, Norton Internet Security 2010 gives you a deep but uncluttered toolbox from which to keep your computer safe, maintain a high level of security, and access system management features. Norton's Quorum is the big new feature this year--combined with the expanded Norton Insight, Symantec is looking to improve security while riding on the news of its overhauled performance.
The center and right side of the main window are taken up by Norton's core protection features: computer scanning, network defenses, and Web protections. To the right of each feature are quick toggles for key subfeatures, and to the right of each of those is an "i" icon that reveals more detailed information when you mouse over it. Next to the network defenses, for example, you can toggle the firewall, intrusion prevention, and e-mail protection
the best feature of Norton Internet Security 2010 is less CPU power consumption. however, its 2011 version is now holding the market and people are switching toward other spyware detective and removal software.i think hone users are still in use of Norton Internet Security 2010 today.
