I dont know if this is new but its new to me and I just seen it happen like 2 seconds ago with the ads displayed on the sidebar of any Google search check out the screenshot its an AJAX based thing

Its not a new Google feature but its my new AntiVirus software telling me which pages are safe and which ones are not safe to view but I really thought it was a new feature for a split second before I hovered my mouse over one of them.
