Received a call. When I asnwered I got just silence.

got a call this afternoon. i said "hellooo" 2x then finally they said "helllooo" and then they asked for me by name and i said "speaking" and they hung up! WTF!!

Got a call.  Some Indian dude was trying to tell me that my Windows computer was infected.  I'm a security professional.  I can guarantee, it is not.  Clearly it was a blind call just trying to rip people off.

I just had the same phone call from someone who had an Indian accent and was trying to say he was from "PC Secure"  who works in cooperation with Microsoft to inform people on how to make sure they do not have viruses.  I'm not naive but I was curious to see where he was going and I played along for a couple minutes.  He would ask me to click on "My Computer" icon and tell him what came up when I did that.  Anyone who works in IT should probably know what happens when you right click on an icon.  I heard him talking to someone in the background and he would not listen to anything I was saying.  I finally just said I wasn't comfortable with this phone call and hung up.  He was rude to begin with and I'm positive this was some sort of scam.

Same here.
Our phone services (and especially our land lines) are under assault by a new breed of invasive, nuisance phone calls being spawned by a new kind of marketeer who doesn't give a damn about us or our privacy.
Please register your complaints with your phone company.
If the phone companies and carriers won't do anything to stop this, our only choice will be to get our phone services some other way.
