Caller ID showed OUT OF AREA. Caller left no message. I don't know anyone in California.

Caller ID = "Santa Clarita CA"    They left no message. ***BLOCKED*** ! ! !

This called identified himself as from "Microsoft" and wanted to let me know that I had a virus.
This is a scam caller of the worse kind.

Same message -- Microsoft calling to say that I had a virus.  I told him he was lying and he hung up.

Spoofed number for "Keene Construction", from the Los Angeles area.  Not like I'm going to have a contractor from California do work on my house in Maryland.  Got to be a scam.
