When I was running Norton 360 I would have 2 icons in the system tray about 25% of the time when my PC started up. I moved to Norton Security and for the first couple of weeks there was only one icon in the tray. Lately the double icon issue has come back in NS. It seems that this glitch has found its way into Norton's newest product. Since this issue has been around for a long time I guess we will have to live with it.
