[help] Which File To Reshack For Norton Tray Icon?

Any help would be appreciated. I am trying to switch to os x type tray icons and the yellow Norton icon is a sore thumb compared to the others. I already have an icon in mind, i just need to know the file to look in.

I don know about norton but I've tryed to change other anti-virus icon ans the anti-virus replaced itself again... maybe itś just protection...
