Avast flagged Tutanota desktop app as a virus and send it to the virus chest.

That. What the title says.
How can i proceed?

Thank you in advance.

Have you sent it to Avast from the Virus chest as a possible false positive ?

No. How do I do that?
And is there a chance that I send without knowing the encryption keys and/or the password?
