NOD32 4.0 messes with Thunderbird?

[VidKo]

Since I installed NOD32 4.0 beta I'm getting the following error in thunderbird, which unfortunately remains after I uninstalled NOD32:

What certificate is it? Please click on View certificate and post a screenshot of it here.

My sincere apologies.

I'll have to figure out the solution untill I can start testing NOD32.

[EDIT]
The culprit my email provider, because his certificate expired. I just unticked "Use secure connection" and the problem is gone.
