For weeks (months?) my Norton Security product stops launching after a few successful attempts. I follow the instructions, use the removal tool, and reinstall the product. It'll launch a few times via either the taskbar or desktop icons over the course of a week, and then that's all she wrote. Unresponsive. I remove it, reinstall, it launches a handful of times and then quits again. I think I've reinstalled it close to ten times now, possibly more. It happened with Windows 8.1 and now it's continuing with Windows 10. Any suggestions regarding a fix would be greatly appreciated.
