Well you are going to need to figure out or retrieve the password for your iTunes account (you can use forgot password.

You have to understnad that there's no legitimate version of Torn on the Apple platform, so whatever you downloaded was not the game that you wanted - so who knows what the app you downloaded was doing. Hopefully using iTunes you can remove the app, if not then it's going to be a very expensive experience.

Be aware that you've probably voided your Apple warranty, so good luck there!
