Norton Internet Security 2011
Security suite with anti-spyware
- Comprehensive threat coverage
- Excellent malware removal
- Good firewall
- Little impact on computer performance
- Mediocre spam filter
- Dark interface
Feb. 2012: A new version of this software is available. Please see our review of Norton Internet Security 2012 (*Est. $70).
If you want an Internet security suite that contains anti-spyware software, reviewers recommend Norton Internet Security 2011. In addition to anti-spyware software, Internet security suites include a wide range of protection, including antivirus programs, firewalls, spam filters and parental controls. Norton Internet Security gets the best reviews year after year for its excellent performance, and the software receives high marks in independent lab tests. Reviewers say Norton Internet Security 2011 removes a high percentage of malware and spyware without many false positives. Its robust firewall is also widely praised. The software runs quickly and, unlike previous versions, has a limited impact on computer performance. However, some experts say the spam filter needs improvement. We also saw a few complaints that the dark interface is hard to read.
The best reviews of Norton Internet Security 2011 come from independent test labs like AV-Comparatives.org and AV-Test.org. These sources conduct comprehensive testing and rate each program on its performance and effectiveness. PCMag.com and PC World are also useful because they conduct their own basic tests, in addition to relying on test results from the aforementioned labs. Shorter reviews from PC Pro, About.com, TechRadar.com and other sources are also helpful.
