Received a call from (902) 530-5935 from a person who identified himself as Brian McKilllroy. He was claiming to be with Microsoft Technical Department in Florida and went on to advise me that my computer is sending out Error codes to Microsoft. If I would open my computer he would guide me to make corrections. I asked him for a phone number I could use to call him back to confirm he was with Microsoft and he gave me (902) 250-6392
