My phone was just sitting on my kitchen counter and all of a sudden the AVAST alarm started going off that it has been lost or stolen. My husband also received texts letting him know my phone's location. If I click unlock and type in my pin, a circle just spins endlessly. My husband continues to get a text every 5 minutes showing my location. I cannot access anything else on my phone although I can see texts as they arrive and see calls coming in. Please help me unlock my phone!
