<prompt> Human: Hopefully this is the right spot to ask this question. I overheard my wife talking to her mother about a pop up on her computer. Long story short, they had hundreds of errors and Microsoft sold them some software. Basically, 800 was charged on their card.I asked several times to make sure that this was their credit card and not their bank card. I told them to call the card company immediately and dispute the charges. What else should they do?  <response>: Time to set up new accounts on their computer so they dont have any administrative access.Cancel the card, dispute the charge, educate them.
