I really don't trust any 3rd party pirate app stores like this, it's the #1 reason phones get "infected".
Oh, one thing you may want to look at is rooting it then installing Cerberus (it's a paid for app, but worth it!) - loose your phone and you'll find it soon enough, or take pictures / videos / audio clips if you think it's been stolen, or if someone tries to unlock the phone with an incorrect pin/password. All of those get emailed to you.
