when i turned my computer on i got a message from norton that it was running a virus and spyware definitions update then it came up that it hadnt worked and that there were 4 problems to fix so i clicked fix and it all failed, norton suggested i deinstall and reinstall norton so i did and now when i reinstall it a blue screen comes up asking me to restart my computer and if the screen comes up again there is a problem and this just repeats.
