This ads will replace any ads of our web browser with the same width/high ads setup on any web page. I have tried to clean out but it NOT success by now and still don't know where it come from, guess that this will come together when we download/try to download some thing such as software/pic/movie from bad website. Once I found how to fix I will then let you guy know later. Good luck! and good luck for me too...
