iPhone 4s stopped working with no apparent cause. Soft reset did nothing.  Apple symbol appears off and on when on charge, but nothing more.  By holding home button and plugging into iTunes brings up a window indicating a need to restore.  Attempt to restore on iTunes results in failure due to error #21, which it says likely relates to security software. Have had no success disabling antivirus and firewall. Diagnostics: iTunes communicates ok thru security system. What to do?

iPhone 4S, iOS 6
