"Norton Insight judges the files as safe because it uses data collected from millions of 'Norton Community' members, in much the same manner as Panda Internet Security 2009 and IHateSpam. Based on this data, Insight lets Norton Internet Security 2009 avoid scanning files that are found on most computers and statistically determined to be trusted."
"Norton Internet Security 2009 represents a dramatic improvement over its predecessor. Security has been improved but the most noticeable gain has to be responsiveness: less intrusive than Norton 360, sometimes it's hard to tell if NIS 2009 is running. The protection it offers is hard to beat though its spam controls could be better. Recommended."
