I live in FL and received a call on 3/30/16 from Fall River, MA. I do not answer calls from CID/persons I do not recognize. Not finding any info on 800 notes I searched the white pages.com and found the following
Scam or Fraud
Flagged as Tech Support Scam

Verizon Landline
Fall River, MA
It’s the old Windows/Microsoft says your computer is sending out viruses. Guess they are too stupid to realize that that scam is like beating a dead horse
