Just to add just because it does not work on your PC does not mean it slows down everyone's PC. I have read many places MSE is light yet it slowed down my machine, I do not go around everywhere saying it's bad because it slowed down my machine. No machine is 100% alike once it gets into the users hands. If you have a product you test and it does not work as expected send tech support a email and have them look into it. I have not found one security company who does not like it when users email tech support to report problems. Most company's rather like that so they can fix their product.
