I bought the norton 360 protection, for my computer at home. When I installed it, my computer went off line and I could not, for the life of me, get my computer back on line. I was very upset! So I went down stairs, ate dinner, put the kids to bed, went to bed myself, and had sex with my wife. There was nothing else that I could do, until the next day. I took my computer to the shop and $150.00 later, my computer is up and running with no Norton 360 any ware on my computer. I am now looking for a better antivirus that doesn't inbed it self into computers.
