Fightbackproxy appears

I recently figured out how to get Ubuntu and now I am in my Synaptic Manager trying to download several things. Whenever I attempt to download or refresh it I get a message that fight it could not connect to www.fightbackproxy.com:8080 and I have no idea what to do. I have been to the site before, although I did not download anything. I have done a search for it on my Computer and I still can't find it. Can someone explain this to me?

Edit 2: Okay I fixed it. Had you read edit 1 it started with one small mess up.
