"Unfortunately, netalpha has stopped"?

My phone has a box that won't go away, it says Unfortunately, netalpha has stopped" I keep pressing ok and it just won't go away. I have already done a master reset on my phone, which has erased everything, but after doing the master reset and my phone reboots and turns back on to the original "select language" screen that box pops right back up.....PLEASE SOMEBODY HELP!!!! I HAVE NO IDEA WHAT ELSE TO DO......

THANKS IN ADVANCE!!!'''
