Itunes, Major help with shared files...

Hey, Hope this is the right place to post this?
I am on a local in house network, well ages ago i had limewire and since delted it, simply dont listen to music much, well now another computer on the network has Itunes. My old limewire files are showing up in shared section of their computer, even if i uncheck the box saying "Share my library". Now if i search for shared playlists i find my old limewire stuff. I was wondering where on my PC i can find this folder and delte the contents.

Please note i have uninstalled limewire the proper way with its own uninstall button thingo and beleive i deleted the associated downloads.

Thanks.
