No you use IE as a browser. Google's browser is Chrome.
You can get a pop-up blocker for IE but Chrome will come with it's own built in blocker. I prefer Chrome to IE personally. You can just install Chrome and start using it. You might want to set it as your default browser to open URL's in say emails etc.
You need to keep IE available on your machine (if you change the default browser to Chrome). Some sites eg Microsoft require it for certain things - and historically some banking sites were a little touchy about Chrome, Not sure that the latter is still true.
