you can't rely on norton antivirus.

but if you check your active processes and directly confirm a problem with flash player 11+, uninstall your current flash player (http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-mac-os.html or http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html) and install an older version:  http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
