It is supposed to help guard against potential ransomware attacks. Anyway, when I realized that this was the blocking agent, I created an exception for Calibre. Once unblocked, I created a new Calibre Library, copied back the book folders into it. And finally I had to use the 'Restore Database' tool in Calibre. Now all's well again.
You guys at MobileRead rock! Couldn't have done it without your help.
