In the 2010 version of its well-known antivirus program, Symantec continues to build on the unexpected progress it made last year. In addition to maintaining the quick load and scan times, and significantly smaller system footprint, Norton 2010 includes a behavioral detection engine based on both behavior and reputation.
Called Quorum, this new engine doesn't adversely affect Norton's performance--a major concern after years of system-crippling sluggishness. It works in concert with Norton Insight, introduced last year as a whitelist-style guard for ''trusted'' files. By examining your files and how they behave--both locally and when trying to access the Internet--and comparing them with other Norton users, Symantec claims that it offers better protection than its competitors. Like its competitors who also have behavioral detection systems, however, Norton allows you to opt out of anonymously submitting your data without sacrificing the protection that Quorum provides. Third-party detection and removal ratings are not available for this new version, but last year's results placed Norton in the upper echelon for efficacy.
