Avast made great strides in its previous update. Version 5 set the stage for the modern massively popular and free security suite with a new interface that ditched a quirky late-''90s jukebox style for a more polished look. Easier to navigate it also became easier to add new features installation: Installing Avast is a painless process that compares well against its free competitors like AVG although--like those competitors--it''s much slower than installing paid programs like Trend Micro Kaspersky or Norton. interface: Avast 6''s interface is virtually identical to the previous version''s. Perhaps the most major change aside from a slight lightening of the gray in the color scheme is the removal of the Windows Explorer-style forward and backward buttons. We actually liked those since they made it easy to return to a previous pane no matter how deeply into the settings you had explored. ----annother change in version 6------ The only other change is the addition of the Additional Protection tab to the left nav area which hosts the new AutoSandbox and WebRep feature controls. For users new to Avast the sleek user interface is a change that came at the end of 2009. The gray-and-orange color scheme stands out well on the screen and the tab-based navigation on the left makes it easy to navigate between features. Highlighted with the familiar security colors of green for safe and red for dangerous the Summary tab gives up-to-date info on shield status auto-updates virus definitions the program version and whether the silent/gaming mode is on. There''s also an unobtrusive ad urging you to upgrade to Avast Internet Security 6.
