i got a call from the same number Mr John said we are receiving error and warning from your computer i did't
believe him but when he said let me show once ,then you would be able to believe me ,, i thought lets see
them he show me each and everything which he was talking about and then he fixed my computer ,,and he told his company name so they are good ,,
Why would someone give a shady company $400 - $600. to fix their computer? You can get a new computer for that price, or you can get very good anti virus software for $20.00.
