I'm having the same problem and apparently it's widespread.  I have an Asus which was originally Windows 7 and it automatically updated to Windows 10 while I was not using it.  I have never used Norton nor McAfee.  The Version is 1606 and the OS Build is 14393.1593.  I thought I fixed the problem by doing a ChkDisk but apparently not.
