I have been using SpyBot, SpywareBlaster, and Lavasoft Adaware Pro for a
few years, but I am always concerned about the fact that not all
programs find the same problems. I am thinking about adding (and
possibly replacing some of the older programs) SpySweeper because of a
review that I read: http://anti-spyware-review.toptenreviews.com/#top

Am I asking for problems by adding yet another program?

Thanks
