How can i get rid of these messages?

When I turn my computer on I get two error messages when the home screen comes on.

NAV UPDATE

Update Antivirus Software Please Wait.

Then another window opens with

Run Time Error '11' Division by zero.

Ive had this message from Norton ever since I done a system Restore. But my Nortons fine and up to date

I also get this message

ERROR

Try using Ccleaner to uninstall AOL.

http://www.ccleaner.com

Its a useful free utility.

Try the Issues button and see if there are any references to AOL, try running the issues tool to remove them then re-boot ans see if the message is gone.

If not you may fine it easier to re-install AOL then uninstall it again.

Try searching the Norton forums for help with the error message, or get help from the company since you've paid them for the software.
