Several times a week my Norton 360 does not start up. If I try to start it by clicking the icon on the desktop it just silently does nothing. This was happening with version 3, so I downloaded the latest version 5 and it continues to do this. I have an HP Pavilion dv7 running MS Vista. All other start-up programs always start. This morning I had to reboot twice for Norton 360 to start.
What is going on?
