Received call from someone claiming to be from Windows and that my computer was infected. (They were apparently receiving 'error' messages from my computer. I asked specific questions which in his poor English, he could not answer. I asked for his number and this was the number I was given. Clearly, not a legitimate call.
These are scum sucking criminals. There is no way that they can trace error messages from your PC and know what your phone number is. DO NOT FALL FOR THEIR SCAM!
