Microsoft's Security Essentials
has officially reached version 2. Ever since its launch last year, MSE has been a favorite among free security software connoisseurs. It's consistently ranked alongside the best paid anti-virus options out there in terms of detection and removal. And it basically blows its free competitors out of the water. The latest version adds an improved heuristic detection engine for weeding out threats that haven't been positively identified yet. It also integrates with Windows Firewall and Windows Filtering Platform (the latter is Vista and Windows 7
-only) for protection both from the Web and on local networks. If you've already installed Security Essentials you should find a notice to upgrade under the app's update tab. If you haven't downloaded MSE yet, well then, what are you waiting for? Head over here
and grab the latest version to protect your computer for free.
