ContextEdit from www.pcmag.com (http://www.pcmag.com/article2/0,4149,1937,00.asp) will let you remove it, The program isn't free any more, but you can buy a few programs for a quite reasonable price.
I have an offensive item in my drop down box when I right click on a window. I am using XP Home on a Gateway 700x 1.8 ghz, 512 ram, Norton Internet security 2004, Spybot S&D, Adaware 6.0,and Linksys router. I connect via cable. I have tried to search for this item to remove it but even though it is in the drop down the search comes back empty.
