Also getting calls--does not leave message.  Supposedly a landline in Seattle/Tukwila.  Came close to paying for a reverse lookup.  If someone already subscribes to the service, please do rest of us a favor and expose who/what this caller is.

Got one too, tried to call back, says"disconnected". wierd

This is one of those calls seeming to originate in India that seeks to get you to open a portal on your computer to allow them to fix a "problem" which they have identified.  Only an idiot would accept a call from an noisy obviously WAY offshore call center as being from Microsoft - assuming that they actually had people somewhere monitoring the health of every computer on the planet.  My wife answered a call this morning.  I've had several over the past few weeks.  Next time, I'm going to play along to see what they are actually fishing for.
