Encrypted email account

I recently added a new email account to my Thunderbird email handling app.  The email account is encrypted and now AVG keeps putting a popup on my screen telling that I need to set it up to handle encrypted emails.  I am not sure how to go about doing this.  I went on the suggested online FAQ to fix it.  I got to the point of the instructions where I have to do something with the email client so it connects to AVG email scanner instead of the actual email server and I'm not sure where to find that.
