Norton isn't the best way to fix it. Many have found norton to be a false sense of security. go to www.tweaks.com. they can probably get you though the rough spots.
If you have Windows XP, go to START %26gt; RUN and type in cmd and hit the enter key. At the prompt, type chkdsk /f and hit enter. You will then be asked to reboot. If that doesn't work, try system mechanic. You can download it at download.com or pick it up at Best Buy or CompUSA.
Try another anti virus, diiferent anti viruse pick up different things
