I have windows xp on my 2001 dell computer. Back then, I had AOL and other programs which have been deleted. When I run my anti virus programs, these programs, though deleted, still show up under documents and settings\all users\application data\. I deleted AOL, Norton, etc. years ago along with other programs. Why are they still there and how can I get those files deleted out of my computer? I'm not that computer literate so I really need an easy step-by step instructions.
