@songdogtech - I have done all of that already, and I mean ALL - core WP files new, clean and shiny, plugins deleted and those needed only reinstalled. This is why I found the code in the wp-options, option_value table. I was hoping my find might help others along the way as well. FWIW, all WP and plugins were/are up to date and my passwords are 14 characters with numbers,letters and symbols.
So does anyone know how to just delete the value that contained the code or, where I might look to find the code that's inserting the value? It's odd that it is still there considering the core WP files are shiny new and the plugins too.
And my iMac is not infected nor are any others on our home network.
