When ever I load the computer I have noticed in the hidden icons that Norton has a red cross against it indicating there is an issue. This always disappears after a minute or two and Norton shows as working as normal. Today I managed to open Norton while it had the red cross and it said sonar was not working. I used the fix option but it failed. However after 30 seconds or more it fixed itself and Norton showed as working as normal. Is it likely the sonar issue is what causes Norton to show as having an issue on loading and is it normal that Norton shows as not working on load only to fix itself?
