Who called from 2817520147

this is a scam - 2nd time I received from this # .

Have had 5 calls in the past 3 days from this number saying they were with "windows".

Hard to understand the guy, he has a thick accent. Claims to be from microsoft windows and says my computer is sending out malware signals or something like that. When I ask who's he calling for he doesn't know a name, wants to email me stuff.

Answering machine took call - caller kept saying "Hello" many times before giving up. ID "Unknown"

Phone rang. Stopped what I was doing to answer it. It stopped ringing. Tried to call back because someone was saying hello before they hung up. A recording said the number was not in service. I have love ones with 281 numbers. Wish I knew who they were.
