I never clicked that one, but if it was showing you endless messages in small message boxes then it has nothing to do with your PC. It is just a 'Java Script' that will keep on showing those messages every time you will click it. If it is giving you any messages in the system tray or anything else then it might be an Ad-Ware or Mal-Ware ...

From what I can see here, it is just a script ...
