I like MS Security Essentials because, basically, I've already said "I'm willing to trust Microsoft for my system software." Norton, Symantec, McAfee, they all are terrible companies that I'd happily keep off my hard drive given the choice; when I'm using Windows, I've already accepted MS. Plus, since MS knows their OS better than others, they've managed to make a security system which doesn't bring a brand new machine to its knees.
