How can I turn off the anti spam toolbar in TB?


how can I permanently deactivate the Bitdefender anti-spam toolbar in Thunderbird? Turning the anti-spam module off in Bitdefender has no influence and if I deactivate the add-on in Thunderbird (or even delete the *.xpi file in the profile) it’s back again after restart.

I asked the same via email form to the support – but no answer yet.

Any tips?
