I just got a call from Windows Technical support about maleware hackers are downloading on to my system. I told them our connection was breaking up and asked for a call back number in case we got disconnected. What are the odds that the phone number I got is legitimate? (I'm at work and have no intention to outbound from my phone) Should I notify any sort of law enforcement? Do they even care about this stuff?

Yes I know it wasn't really windows technical support in case that wasn't obvious. Clearly it isn't obvious. I know exactly what scam this is. I've been using a computer longer than some of you have been alive (assuming you're a teenager).
