HELP - Kaspersky deleted my entire InBox in Thunderbird

[Stephen DD]

In the background, it automatically picked up an infected email in my InBox in Thunderbird and deleted it without notification. However, the InBox is a single file. You can't just delete a single email without deleting the entire folder.

I've looked in Quarantine but there was nothing I could restore (I was hoping to find my InBox quarantined so I could restore it. No luck)

What can I do? It's an IMAP account so every InBox on every computer is now empty.

Welcome to Kaspersky Comunity.

 

Please provide version of K. product installed.

 

Did You make any change in Your K. config? Usually K. does not remove ThunderBird InBox files, in fact, You can search in this community that recently some users came with some issues with their K. because K. could not finalize completely a mail disinfection 🤔

 

Also, if it is an IMAP account, then the messages should be still in the server 🤔

 

Could You search in Your K. product Reports, and post a capture of the specific detection and what protection module involved in the deletion?

I have Kaspersky Standard - Family pack of 5 licenses.

To be honest, this is not "feeling right". You're right that it shouldn't delete an Inbox. I'm going by the reports that a dozen infected files were deleted by Kasperspy at the same time as the Inbox was emptied out. It might be a case of coincidence, not causality.

It's a shared account, so it might have been caused by another user doing a clean out. I hope it is. I'm trying to find out.

I may have jumped to conclusions in my panic of seeing thousands of my client's emails disappear while on my watch. (I'd loaded his account into my Thunderbird to confirm his account settings were right, and suddenly all his emails are gone. Imagine my horror.)
