Norton Internet Security
A single main interface replaces the tabs found in prior releases. New features include Norton Insight which whitelists files based on reputation, cutting scanning time. Virus signature updates are now delivered 5 to 15 minutes, supplementing the reliability tested updates issued by Symantec every several hours. However, such updates may incorrectly identify files as malicious, and users can elect not to receive those updates. Spam filtering was reintegrated in this release. The add-on package now includes information filtering and parental controls. The exploit scanner found in the 2007 and 2008 versions was dropped from this release.
