Be very alert and careful. A number of our customers (interestingly they all seem to be Sympatico customers) in the Dufferin area are receiving phone calls from someone with an East Indian accent claiming to be from Microsoft or Sympatico. This person will tell you that your software is out of date and ask to be able to log into your computer remotely. When you allow this, the person on the remote claims that your computer is infected with malicious software (often showing you a website to back up his claims) and will inform you that it will cost X amount to fix it, which will be billed to the credit card you provide them.
THIS IS A SCAM. Do not give these people any information. Hang up the phone. Log the time that you received the call and report it to the Canadian Anti-Fraud Centre at 1-888-495-8501.
