Who called from 6460017890

Caller disconnected as soon as I answered.
Immediately called this number and got message that this number is no longer in service.

Received call that my computer is sending internal security errors via Microsoft firewall.  Microsoft did not show on telephone ID.  I tried to call the number back and you cannot call the number.  Scam is what it sounds like to me.

Picked up, no one there - scam

make sure you put the phone sideways

Have been receiving unknown calls past few weeks;  Never anyone to talk to???;
