Beware of rouge search tools.  Read the fine print before you act. As I am here at 3am working on my youngest machine trying to figure our why he has limited access on his machine to the Internet and I have none.  The common factor here is my son is trying to take over all the machines in the house.  Well back to the issue he has download a new search bar and any time you type an address in IE it triggers a search request, even on valid web addresses.

Moral of the story if its free.....thats right there is a good chance you will be removing it at 3.  Yes I mean AM.
