One other comment about MBAM, if it's not too far off-topic ... last I heard (late winter or early spring), they were planning to convert to incremental def updates similar to the way avast works, sometime this summer. That'll clean up its one real flaw, since it currently updates by downloading the full database, currently somewhere around 4 or 5 megs. And it'll put MBAM way ahead of its competitors like SAS.
