Perhaps you should reverse the order that you run the scans. Personally AdAware has caught more false positives than true detections, the same with spybot, so neither have detected much but that is more down to the way I use my system and the proactive measures I take. Buy, I won't be uninstalling either I would always have two to compliment each other. The same as many do with a back-up AV, that AV may never catch anything that doesn't mean it is bad.
