Question: how do I delete the  search web block on my computer? 

Answer: I am not sure exactly what you mean, but it sounds like you may be talking about a tool bar that you have installed in your browswer.  Click on "view" and then see what tool bars you have installed.  You can uncheck the features you wish to remove.  Or you can go to the "add/remove software" function in Control panel to uninstall the unwanted tool bar.
