Recently upgraded to Windows 10 on my ASUS R500A (Intel Core i7) . It appeared Norton Security was working but my entire operating system became bogged down to the point where my disk usage was getting stuck at 100% for way too long and even some keys were delayed to the point where I could not type certain letters. I uninstalled Norton and turned on Windows Defender. My computer is now operating properly with no disk usage problems and letters working fine. Will Norton Security work properly with Windows 10 at some point soon?
