Same scam but they have information about my address when I registered my computer (it was my former address). The lady after threatening me of cancelling my registration passed me a guy with same Indian accent from the info department. He told me calling from Florida and when I asked him to tell me which kind of computer I have he hang up. My computer too was not boot for 2 days and when I told them that they changed their version saying they are receiving error messages since 3-4 days!! Clearly a scam and I'm in Montreal, Quebec too so be careful.
