My name is Charles, and this is how I got scammed, but survived it. I was on my computer, using a web browser, and suddenly there came a flash across the screen, saying “This computer is blocked.” This window popped up claiming it was from Microsoft, and that I needed to call this phone number to unblock my computer. I couldn’t get it off my screen. I’m a realtor and I need my computer. So I called the number. A man answered; he said his name was Samuel Lester and that he worked.
