Fortunately, the call went to voicemail, and of course, they left no message. I am well aware of the scam Ben Dover reported. (Ben, really sorry they got you.) Dangerous people, do not answer or attempt to work with them.
This was someone from the Micro-Soft anti-virus response team letting me know that a hacker was trying to break into my computer. They gave me a website to go to so I could give them my password and have them block the hacker from taking over my system. I did that, but I think the hacker still broke in, because my computer only shows a black screen now telling me to send bit coins to somebody. They also take light coins. I don't really know what to do, as I don't have any bit coins or light coins and I don't know where to get some.
If you actually let this caller into your computer, you let the hacker into your computer and your personal data has been compromised. I suggest you take your computer to a reputable repair shop so they can clear out any viruses these scammers infected it with. You will also want to change all passwords and log-ons as well as monitor your bank accounts and any other financial information in your computer.
I'm on vacation and these random robo-callers called my cell that I haven't used in months. Shady AF. Yeah, clue #1...if they're calling you and don't leave a message, don't call them. I just posted this as a 411 to others.
