Norton Internet Security 2012

Security suite with anti-spyware

  • Comprehensive protection
  • Lots of extra features
  • Low impact on computer performance
  • Streamlined, easy to use interface
  • High number of false positives

Experts say Norton Internet Security 2012 fixes most of the problems found in earlier versions, and it is  the best all-around Internet security suite money can buy. The core components of the suite -- antivirus, firewall, anti-spyware, anti-spam and anti-phishing -- are all very effective (and sometimes perfect) in testing, there are a bevy of extra features such as parental controls and password management and the interface earns high marks for being uncluttered and easy to use. Norton's impact on system performance is lower than ever, as well. Norton's one major downfall is its SONAR behavioral protection system; while SONAR helps Norton block new malware very effectively, it is often overly enthusiastic and frequently flags obscure, yet safe files as being malicious. If you need to protect only a single PC or want to spend less money, consider Bitdefender Internet Security 2012 (*Est. $40), instead.

6. Expert Reviews

Kat Orphanides gives Norton Internet Security 2012 a 4 out of 5 star rating. The program allowed 4 percent of viruses through in the publication's testing; not much, until that's combined with Norton's higher sticker price. That combination prompts Orphanides to recommend Bitdefender Internet Security 2012 instead.
