Centurylink.net Webhelper Safari Redirect Bot-How Do I Remove it? I have completely reformatted my computer, and it is still there

Hello. For a few months now I have had a redirect bot on my computer (Safari Redirect). I got it after I downloaded Maverick. I have been in touch with Apple Support and have done several things to try and remove it. I have reset Safari. I have deleted all extentions and add ons. I deleted Safari and reinstalled it. I erased all free space using Disk Utility. Finally, I reformatted my disk drive completely using Disk Utility and reinstalled OS X Moutntain Lion from the computer. We also attempted to reset the DNS cache, but I am not sure that was successful because I coul not see whether it accepted my password or not.

The redirect is an address bar redirect and it used to redirect me to a fake Centurylink.net webhelper page. It does this at first by adding 20's and percents between my search words. Like this: lexeon%20titan%2010000%20gpd%20commercial%20ro%20reverse%20osmosis%20whole%20hou se%20water%20filter

Before I reformatted my computer, it was taking me to a fake Centurylink.net Webhelper Page or a fake GoDaddy Page. Since I have reformatted my computer, Safari cannot find the server it used to be redirected too.

Now I get a message like this:

Safari Can't Find the Server

Safari Can't Open the Page "French%20Huguenot" because Safari can't find the

server "french huguenot"

I put Java on the highest security setting possible and that seemed to take care of the problem for awhile. However, it is now back. I just ordered a Mountain Lion OS X disk from Apple.com and I am going to reformat my computer again and reinstall with that disk because I cannot figure out what else to do.

HELP PLEASE?! DOES ANYBODY ELSE HAVE ANY IDEA HOW TO FINALLY GET THIS THING COMPLETELY OFF MY COMPUTER?!
