I came across one of these a couple of weeks ago. I knew it immediately it was a scam because the guy had an indian accent. I played along just to see what he would do.

He directed me to site support95 .com. Apparently, there is a similar site called support18 .com. From there he told me to download an exe file. That was where I stopped. I did not know what would further happen.

If anyone wants to try it: Call 18005589204. Tell him you got a voicemail of someone from Microsoft saying something about license expired. I would love to know what ultimately happens.
