I've been using Norton for decades - rarely a problem. Just purchased a new 360 (5 devices). Installed and works well on two devices but major problems on my laptop. Tried installing - just stopped my existing Norton 360 ( premier ) from working at all. Tried usual uninstall via Windows Control Panel - will not allow Norton to be uninstalled at all. Downloaded and saved Norton Removal Tool. Clicked on it and just doesn't run - does nothing - so looks like my whole system is locked out of doing anything with Norton products. Running Windows 7 on good quality Samsung 9 series laptop. Where do I go from here? Ian
