It is not easy to deal with Amazon Smart Search:
Amazon Smart Search not only took over Firefox, but Google Chrome and IE. I tried uninstalling everything from Amazon. I was looking at some PC cleaners, and driver update, but do read carefully and have no idea how Amazon Smart Search took over. I am really pissed at Amazon. In the meantime, I have to get it off my other two search engines. Does anyone has any ideas of how not to get into this situation again, I would appreciate feedback.
