Since today, Update Vers. 78.4.1. ALL my GMX accounts does not work! SOLVED: caused by Avast
Good day. I have a massive problem with all my GMX.NET and GMX.COM accounts since today I started my computer and it runs the newest update. I get message windows that the Certificate is not valid. Pardon?? As well I tried to set up an other GMX.NET email account which I did not run on Thunderbird until now. It does not work and I get a message the certificate is not valid and Thunderbird stops the ongoing process since the website (GMX) has an unknown identity!
I can not believe what´s going at present Does it have a reason in the PGP implementing? What else is the problem?
Thanks for quick help, I am sure I am not the onliest with such a problem.
Cheers

Run Windows in safe mode and disable any startup setting in Avast, then run TB. You may have to uninstall Avast (recommended) to completely avoid its interference, or at the very least disable Mail Shield and SSL scanning.

What's the antivirus? Avast is one example of an AV that interferes with TB, in the way that you report.
Thanks for your message. You know my answer? :) It worked on Friday last week with TB 68, today it upgrades and I have problems. BTW, now all my accounts does not work. I have to use my old Outlook, which works perfect! Serious answer: Yes, I use Avast and it was my first idea to stop the firewall and restart TB. It does not help.
As I see the messages here in the TB forum, I am not the onliest who seems to have massive problems after the update to TB 78.
What else can it be? Thanks for any help!

Thanks for your patience and help. I did straight away un-install Avast. Start new. TB works. I installed Avast, I use the Premium one, and TB works until I restarted TB :) Did several testings, but nothing else helps then to turn-off the email protection in Avast. Feel a bit unsafe now since Avast in the past (I can not proof the truth :-) , but Avast alarmed me) find the one or the other unruly mail in my inbox folder and blocked it.
Do you know why the TB team touched the PERFECT running V68 and did what they did in V78? Always to give the fault, in this case Avast, to others is also not a help. Any idea how and who will change that specific problems?
Thank you very much at all for your professional help!
The problem with AV identifying a message as 'infected' is it's likely to quarantine the entire folder, since TB stores messages by default in a single, mbox file. If a message has a malicious attachment, the only risk is if you try to open it, at which point the real-time background scanner should detect it.
This issue has been around since the beginning of TB, and is not related to moving from 68 to 78:

The risk of running an OS, Windows 7, that hasn't received security updates for almost a year, might be far greater than disabling the scanning of the profile folder.
