Loss of all stored emails

Hello Derek. I would request you to contact Mozilla support for a way to recover the lost emails. Thank you.

My wife has suddenly found all emails stored in her Thunderbird in-boxes have been deleted. On going to the web mail in-boxes on her email service provider, she finds that those have been deleted also. Does this correspond with any known virus activity?
