This number is a "forged" caller ID. There us quite a nice family living there, who know nothing about what is happening.
So do NOT go crazy and start calling this number! It is a LANDLINE, to a HOUSE in Greeley, CO. Whomever is calling US is forging the caller ID! These calls ARE NOT coming from their house!
Some woman with an accent from India, Pakistan, or Bangladesh, called and was telling me about my Windows computer sending out messages, and that I could lose all my data, and "they" could get into my bank accounts, steal my ID. Which sounds wonderfully like opening the gates of Hell. So she was hitting all the BIG fear "buttons".
There were two problems with that little scene she was painting. One was that I run my Internet connection through a firewall machines, which tracks every connection that goes through it. So I would know about "messages being sent".
The other problem was a bit bigger. I have not had an Internet connection in over a year. I'm using my phone, and it's an Android. OOPS!
