I use windows 7 ultimate and Norton Internet security. Recently there has been between 1 - 3 NIS icons in the system tray. I have tried uninstalling and reinstalling, I have tried doing this using Nortons removal tool too, rebooting and every other suggestion I have seen online. Nothing has worked, I still have multiple icons in the system tray. I am concerned about any glitch in software of this type. Is there a reliable fix for this yet?
