You can keep Internet Explorer - in fact, you can't get rid of it!
You just might want to try another browser for occasional things that IE can't reach.
Example: A few months ago, my ex-bf was trying to reach the website to check on the progress of his car insurance payments. He was using IE, and couldn't get through.
I tried it on Firefox, and it worked. And this remained the case with that one instance. There may be others.
