OMG that happened to me last month. I won't go into all the details, but I had to cancel all my CC and bank account #. I went to the geek squad at Best buy and they scrubbed my computer, then to the bank, got new account number. It took me 2 weeks to get everything back in order.
I usually don't fall for this stuff.
I was looking up a receipe and when the ingred. said continue, I did and my screen came up with xxx and to call microsoft.
I let the scammer into my computer, but called the bank on my phone and thats when he hung up.
Long story short, its a nightmare, but sounds like your mom hung up in time. just keep a watch on her accounts.
I'm proberly your moms age, in my late 80's.
She is lucky she has you to help her, I had no one so it was a terrible day, but I got it all taken care of.
He even got into my phone, but I don't have info on that like most people put everything on their phone.
Best buy was so good to me. The charges to do what they did cost about 200.00. The person was so nice and could see how rattled I was, she waived the charges.
She said, this happens alot, not just to the elderly, but to everyone. I'm lucky I didn't have a stroke, so much I had to take care of at the time.
Keep an eye on her accounts.
