I received a call from this phone number on my Verizon cell phone. I missed so I called back.  An american sounding man told me my anit-virus software on my computer is out of date and to get in front of it and he'll run a scan.  I said I don't even have it; it's in the shop for service.  he started to ask what was wrong with it.  It's true I do have my laptop in the shop right now.  Coincidentally, I just had someone use my debit card fraudulently 2 days ago.  Maybe this is the guy?
