I advocate the use of Lavasoft’s Adaware (I’ve gone so far as to become a reseller of their Plus version). I also highly recommend Spybot Search N Destroy. I have always been very wary of other programs as potential trojans claiming that they are scanning when in reality they are installing or removing all but their own adware or spyware. I just found a fantastic list of such evil programs. I know nothing about spywarewarrior but this list will be read by me quite a bit now.
