Microsoft Security Essentials

I’ve used several commercial AV programs (e.g. ESET NOD32, Symantec, McAfee) and most of the free AV programs (e.g. AVG, Avast, Avira, MalwareBytes). I’m VERY impressed with MSE so far. I’ve installed it on four different Windows 7 systems, with very quick and easy installation and low system resource hit. It has easily jumped to my favorite free AV solution, and I’m seriously considering using it in place of other systems that I am currently have running NOD32, Symantec, or McAfee. If they keep the definition coverage strong, then I think this is a winner.
