How to Disable Java in your Web Browser

Recently a “zero-day” exploit was discovered in Java. Oracle typically follows a quarterly patch cycle meaning a patch may not be available until mid-October. 3rd party applications like Java are frequently exploited, and it’s a good idea to unplug it from your browser. This will prevent infection from this and future exploits.
