Java script error

I have windows xp operating system.last month i had to do a disk recovery and i have ie6.0 every time i get on line and go to any web site i get a “script error message, sometimes it says invalid character line 9 or line 5 do you wish to continue on this page” i can then go up and right click on my Norton Internet Sevurity and disable it and the script error messages goes away. i have uninstalled Nortons and then reinstalled but this does not solve the problem can someone help walk me through this?
