Received 3 phone calls in a row, 1 minute apart each (I did not answer any of them) and then they finally left a voicemail message claiming that they detected suspicious activity on my computer and email. They had my correct email address and my cell phone number. The caller addressed me by my first name. He called himself "Richard" and left a return number of 844-846-9376. My number is listed on the Do Not Call Registry, but apparently it is worth nothing because I get these type calls frequently.
