If Norton found it and placed the infectious file in quarantine then it is probably safe to say that you are ok.

To be sure, Have Norton run its scanner in safemode . It should be able to tell you if all is well then. If need be run it twice to make sure it is all gone.

To run in safe mode.
start your computer and immediately start toggling the F8 key to bring up the start-up page and choose to start in safe mode. allow your computer to continue to strat safemode till your desktop comes up black with icons and safemode in the 4 corners then navigate to the all programs > Norton and run the program.

All it to either quarantine or delete all that is found.
