Definately sounds like a hijacker...im not sure if its the RealPHX one but it may be it. I believe www.talkstocks.com/disclaimer.html is where you can remove it, but if it isnt, http://security.kolla.de is where you can get SSD to kill it off probably since it picks up almost anything.

Edit: Nvm, started my post before the picture, lemme find something.

Actually it is RealPHX, so do what i said.
