Everytime windows10 does an update i cannot open my norton, norton must know this is happening a lot because they directed me to their solution for it and to download the "remove reinstall" tool, this fixes it until windows does an update again, the way windows updates now i am having to "remove reinstall" every 3 or 4 days, i should not have to do this, norton must be at fault or they would not have created the tool, its time they sorted this out or refund all their customers
