I recently upgraded to Windows 10 and since then I find that using any of the shortcuts on my laptop I am unable to access my Norton program. Tech support has uninstalled and re-installed my Norton program 4 times already and each time my ability to access lasts for a day before it stops. This is a hassle as I cannot run file cleanup, scans, etc. Any ideas as to how this problem might be resolved. I have always liked Norton products but am becoming a very frustrated user.
