URL that does not exist in my server

I hope I can describe this correctly. Recently I checked my domain in Yahoo explorer and found one of my site's URL that look unusual. I didnt create those sub-directories and somehow when I clicked, it went to my homepage.

e.g. www.electronicsgoods.com/depression/furniture

Anyone can advise me on how I can get rid of this problem, like how I can clear those depression or furniture folder that does not exist?

Thanks

 

Is your domain parked becase it is

ns2.sedoparking.com
ns1.sedoparking.com

you need to set it to the right name server

 

yes domain parked

 

But how can it be parked when I bought that domain?
