This is a scam. Some fool calling me saying there is a virus on my Windows machine. I'm an IT expert and this idiot thinks he is going to fool me. I strung him along to see what he'd say, caught him in a clear logical issue lie, and he hung up. Called back and got busy signal each time. Do not take this call, do not do anything they tell you to do. They're trying to gain access to your machine.
[***] called himself "Brian Davis", but he sounded like he's from India. Told him he was lying about his name and he wasn't going to get any information and hung up.
I strung them along one time and followed their directions on a machine I have that can't go online. When they found that out they got pissed and hung up.
