Airpush keeps asking me to opt in for interst based ads but i dont want to. how to get rid of this?

Okay so airpush keeps sending me a dialog box on my android. It is asking me to opt in. As I don't want to opt in I select cancel. But the the dialog box keeps popping up every few minutes and due to this my screen or app i am using stops responding until I click the home button. It is anoying and intrupts my work. How to get rid of this box permanently?

Have a look here... Opt-out | Airpush | Mobile Ads Redefined... Or google airpush and read what to do.
