user429, I'm assuming you mean a Toolbar Button so right click your Toolbar(the bar that has Search, Favorites etc.) and if Norton Antivirus is on the context menu click it to uncheck it.
I have Norton Antivirus 2006 installed on my Windows XP computer. On any of my internet screens in the upper right corner I get sort of an icon stating "Norton Antivirus" and a scroll-down arrow. I want to get rid of this thing. How do I go about doing that? Thank you very much.
