Update to the latest version of your favorite browser. Strongly consider updating to Chrome which is currently both the fastest and most secure browser. I personally love Firefox so that is fine too as long as it is the latest version. It is truly amazing how many people are running with the default version of IE just because it is on their machine. Unfortunately older versions of IE didn't prompt to update so millions of people are running with very old and very insecure browsers. Don't be one of them.
