How Can I Open the Quarantine Lock to delete virus, when I've forgotten my password?

Thank you, Agile!

Much appreciated.  Now I understand why I didn't recall or make a note of the password originally.

A day or so after writing for help, I had independently identified the correct password -- though without understanding the process that you describe -- by exhaustively testing every password I'd been using this past year. Finally, I tried the password I'd -- purposely -- only used once before, when setting up my new MacBook Pro several years ago. Bingo. Surpised me (baffled me actually) because I had at that time determined not to use it again for another purpose, as a layer of protective insurance.  Your reply now clarifies the experience.

Thanks, again.
