Avast 5 launched yesterday and it finally has a sleek new look and comes with security enhancements. Coming in three versions, Avast Free, Professional, and Avast Internet Security, it's a huge step up from Avast 4.0. The biggest thing to talk about is the new user interface. It's actually good looking unlike the strange media-player type look in Avast 4.

Avast 5 puts everything at your finger tips with tabbed browsing on the left and quick access to scan and change settings. Check out CNET's demo below.
