Hello!
AMS and ATT stands for Avast Mobile Security and Avast Anti Theft?
correct!
I believe AMS/AAT only at this current time supports only phones with one sim.
patrice58 is correct too. The problem with dual sim devices is, that we don't get a clear reading from Android which SIM card(s) are inserted/in use. This causes the described errorous alerts.
