There should be a menu option to uncheck and disable that feature on the modems web page. 

Review the user manual to see about this feature.

   C7000[v1] or C7000v2? Look for "Model" on the product label.

   What leads you to believe that the ReadySHARE feature is enabled
now?  Did you connect a USB storage device (or printer) to the
C7000[vX]?

   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual.  Read.  Look for a
topic like 'Share USB Devices Attached to the Modem Router".  Read more.
Panic less.

Netgear was defaulting to the "Basic" option for ReadyShare.  So, I downloaded Netgear's USB Control Center and unchecked "Run Basic when windows is active".  That did the job.
