Asian Indian voice, fake name, said they got distress messages from my computer (how could they get that?), I let them have access and they "showed" me everything that was wrong (fake contrived data), convinced me they could fix for $199 a year.
I believed them and when they were done, things were worse. I removed any program they installed and had real Windows tech clean up my computer. I realized the same thing had happened to me last year and told my credit card company it was fraud and was refunded.
