I tried Norton 360 Antivirus after running McAffe for a few years. The biggest difference I notice is that Norton is constantly up selling by finding issues and saying that I need a better product. There are pop ups that constantly show up automatically trying to up-sell the product, I don't understand why when McAfee never did this and worked just fine for 3 or 4 years. I'm canceling my 1 year subscription to Norton 360 after only 4 months and going back to Mcaffe.
