I downloaded AVGAnti-Theft to my Samsung mini a while back. A couple of months ago I had to swop my SIM card. Everything has been working perfectly until last night. Now my phone is locked and needs an unlock password which I can't remember. I have tried the forgot password option and that is not working. Please assist me.
