Historically there have been two antivirus program types and although they are more space related here I use their antivirus on my home PC and laptop and my phone. Unlike the nerve wracking suites of norton or mcaffee etc and the other "freeware" viral programs that are basically upselling you or spamming you the 360Essentials and their host of programs do a terrific job of exactly what all programs should do: Their job without slowing you down, interfering, or requiring much user interaction. I deleted my paid for antivirus the moment I got it on my new windows 10 PC and went back to old reliable 360. Cant go wrong period.
