Installing Mozilla Thunderbird.  AVG says I have to change AVG settings to scan encrypted e-mails, and make some changes in Thunderbird, too.  But I can't see that I have anyything in TBird to accept encrypted stuff and I can't understand what AVG wants me to change there.  Assistance will be most welcome!  thanks, Jean
