IPad app update help!

I accidentally hit "Update all" on my iPad so it started to update all my apps. The problem is I have my textbook on this app, and if you get the update for it, the textbook will disappear.Is there any way to cancel the update? So far, I've signed out of the app store, disconnected from the internet, and turned off the iPad. What do I do now?
Please help, I'm freaking out because the textbook was "school property!

How to get rid of pop up surveys from uwavou?

The survey pops up when I click on links in a variety of websites.It makes a little bell like noise and says I have been selceted from the XXXX area to win an ipad 2. The area changes and is never where I live either.

I'm using the latest version of firefox. Please help as this is driving me nuts.
Added (1). As far as I'm aware I haven't downloaded anything recently, i think I upgraded java but I can't remember if that was before or after the surveys started to pop up
Added (2). This is one website that keeps coming up, site itself does nothing but is just really annoying.
