Playtika or Ruzzle review: virus infected my cell phone

Two days ago I d/l the game Ruzzle to my Motorola Atrix HD cell phone. Now everytime I start to use the phone, a question pops up like: Do I want to chat? or Do I want to d/l "name of some game" and this issue does not ever stop. I am thinking it came to me with Ruzzle since that is the last thing I d/l in several weeks. I clicked on "YES" once to see if I could get a website. And I did get playtika.com.
Therefore, please tell me how to remove this crap from my phone?
