I regularly check in on what's left of the Dell Forums and learned about MBAM from those regulars who remain. They have been very helpful with introducing and explaining various security products over the years. I have yet to have MBAM make a detection of anything on either one of my computers. I also use WD, SAS, Spyware Blaster, Avast AV, Online Armor Firewall, A Squared Free on one computer and the full version on the other free of charge thanks to a special promo they ran, and finally Win Patrol and Spybot S&D!!! Whew!! So I run a rather full load of products partly because of the paranoia...the bad guys are really clever, creative, and relentless...and because I like to help test these things out. As presently constituted, there are no apparent conflicts or excessive use of resources from this line up of programs.
