What Do I Do?

So the other day I was trying to view a webpage that required the Quicktime plugin. I updated the latest version and was still having problems viewing the site. I started to try different things to get it to work. I decided to just start the Quicktime program and see if that did anything. When I started it, a window pops up and says that it has to install so I'm thinking ok maybe this will fix it. Then a second box pops up and I had the choices ok or cancel. I still don't know what the question was. For all I know I sold my soul to the Devil.
