I have a friend who had a problem on her computer and she called her ISP Comcast for help since she uses their Norton anti-virus program. To make a long story short, she had to provide them with both her log in & email passwords and then they wanted to charge her $215 to clean her computer.
That doesn't make sense to me - I'm not aware of any reliable ISP tech support asking for passwords. I know they ask for permission to take control of a computer and then supply a service number the computer user has to enter. Is this something new that an ISP tech support asks for passwords.
She has changed her email password and I recommended to her to also change her log on password.
