Warning when opening Apple Mail

Hi
I have been running avast for Mac for some time now, and I have had problems with the mail- and web shields being offline. But with the latest update it was solved.
But now I have run into another thing with the application.
It displays SSL/TLS warnings when opening Apple Mail.
I’m running Mac OS X Lion 10.7.4.

Hope someone can tell me what the problem is. And by the way I use Apple Mail with my Gmail account.

Take a look at this sticky thread:
