Who called from 2816172787

They called me over 5 times today

Called no message left called back said it was a Skype number and disconnected

Got a call from that number, person on the other end didn't even speak english.  WTF?  Tried calling back, but as reported by others, it's not a number that can be called back.  Next time they call, I'm harassing them.

Received a call, technical department of preventative computer. Right, as if that doesn't in itself sound suspicious.  Watch out!

Received a call, technical department of preventative computer, asked that I remove wires. I hung up after 1 minutes of his broken English gibberish.
