"Most impressive" is one way to describe the latest Norton updates from Symantec. After three years of progressively better versions and significant improvements, Norton Internet Security 2011 and Norton AntiVirus 2011 look incredibly sharp. Gone are the days of crippling system behavior and debatable security efficacy.

Instead, Norton gives people blazing installs and quick scans, useful system-managing tools and security extras like the capability to scan your Facebook wall for malicious links, and most importantly, extremely high ratings in threat detection and prevention. With a 30-day trial that has no other restrictions, anybody who's willing to pay for Windows security should check out these two suites.
