Live Update/Fix Now

I'm new to the forum and am not sure if I have posted this in the right place or not but here goes.

I recently bought Norton Security on line. Everything was working fine until four days ago when Norton showed a red color on the desktop icon so it told me that there was a Fix Now needed and so I clicked on it. It shows that it is looking for updates and downloads. I kept it going all day and it never finished and so I left computer on all night with the LiveUpdates and Fix Now still going. I have turned my computer on and off since then for as of now 4 days and nothing has happened.

What is going on and how can I either speed this, whatever it's doing, up or stop it all together? Any thoughts or ideas would be grateful.
