First Windows 11 PC

My first windows 11 computer in the workshop, customer was scammed into allowing the Amazon Scammers into his computer, phoned me, i recommended to him he get straight on to the bank and alert them for any suspicious activity, they had just tried to use his credit card for an online purchase, checked pc over and found they had harvested his credit card details and passwords, removed a suspicious file that was attempting to keep the remote assistance open and logging key strokes
