Symantec Corporation Internet security and firewall

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.

The Bottom Line: Norton AntiVirus 2009 hits all the right security notes, and its superior protection technologies might even win back some jaded anti-Symantec folks, though for some, technical support may continue to frustrate.

The Bottom Line: A near-perfect all-in-one solution for brand new PCs, Norton 360 v2 may be hard to install and run on legacy machines. However, don't count on Symantec's time-consuming and expensive technical support for help.

The Bottom Line: While Symantec's protection is solid, the overall user experience within Norton Internet Security 2008 could be much, much better. Not all the features work together, and the program could use fewer system resources. We can also do without the addition of paid services within the technical support section.

The Bottom Line: Norton AntiVirus 2008 didn't wow us this year. While the protection is solid, the user experience could be much, much better, and the product itself could be more streamlined. Also we can do without the addition of paid services in the technical support section.

The Bottom Line: For home and student use, we think Norton 360 represents the best value for ease of use, tools offered, and overall system performance. We recommend it over McAfee Total Protection and Microsoft Windows Live OneCare.

The Bottom Line: Norton Internet Security 2007 makes significant gains over last year, including cutting-edge rootkit and behavioral monitoring features found nowhere else, but the overall package could be serious overkill for the average desktop owner.

The Bottom Line: Norton AntiVirus 2006 improves its detection and removal of spyware and adware but lags behind the more proactive McAfee VirusScan 2006.

The Bottom Line: Norton Personal Firewall 2004 does the job, but free ZoneAlarm and the beefier Norton Internet Security 2004 are smarter buys.
