Who called from 4186573521

Called because I have window malicious virus .

Heh, that isn't a prank, it's a scam.  Usually Indians, they call to get credit card payments to "fix viruses" on you computer.

call from Diane Arsenault at 7:30 AM!!!  A call from this  number happens daily with no message.  I don't answer, just tired of this.

Received two calls from this number twice both from Diane Arsenault.  Attempted to call back and receive what sounded like an answering machine voice.

Two calls from "Diane Arsenault" at 7:13 a.m. and 9:12 a.m. They hung up without leaving a message.
