Annoying Popup

On my computer, I downloaded Java and since then popups have been coming up saying "There is a new update available for java!".  At first I would just close them and ignore them but eventually I decided to update it so the messages would go away.  When the message opened up, I clicked Update.  It started loading and then it said "No updates available!".  When I saw that I really got angry.  Why would it tell me to update it if there wasn't even an update.  The only reason I wrote this post was because when I was getting on to blogger, it popped up on my screen.
