Did not leave a message. Has anyone else had calls from these 770-1..-.... numbers?  It doesn't look like a valid number.

*** Scam *** trying to trick me into installing software on my computer. Caller claimed to be from "Windows Support".  Asked to speak to the owner of my computer, and claimed my computer had reported errors.  Had me display the event log from my laptop and asked what kind of errors were in the log.  Claimed the firewall of my computer was compromised, and I should install software to fix.  I did not go to the web site URL the caller provided, and hung up.
