I have just updated Thunderbird to 91.1.0 (64-bit) Win 10 21H1.
I am now getting email marked [SPAM} would this be from BT Virus Protect.
I know TB does not like Mcafee and some years ago I stopped it checking email.
I can not find any email settings in BT Virus Protect.

Solved! Go to Solution.
Looks as though the problem is Mcafee and an update.
BT Virus Protect 16.0 R34 dated 23/08/21 which is about when the issue started.
But I can still not see any email settings.

I have the answer.
Done by McAfee, to stop:
Settings > SCROLL DOWN > Anti-Spam > Turn Off
I believe that settings were changed by an update. The real problem was that at first I did not see the scroll bar.
