I have been using malwarebytes now, it is still small and fast like ad-aware used to be. But I do manual removal even before malwarebytes is run, its kind of the icing on the cake. I have found that mwb is the only thing that can finish off av2009 and its variants too, it is a good tool to have in the toolbox but never the only tool. I still use spybot and pest-patrol on occasion.
