Sending emails with Avast as my virus protector

I am getting more and more frustrated by Avast, when I update the program.

Last time it was updated, my wife spent a day trying to reactivate the sending ability of outlook.

now t seems to be my turn.

I have stopped the scanning of outgoing emails, but I still cannot send them

does anyone have any other ideas as to how I can get Avast to allow emails to be sent - I am just minutes away from removing avast alltogther

What OS?
What error messages?
Tried avast repair from ad/remove programs?

it says something along the line of “Outlook cannot connect to your outgoing(SMPT) e-mail server. If it continues …”

I do not know what the “OS” means

OS = operation system / xp / vista / win xxx

Did you try repair?

I had such a problem with Thunderbird. And got a hint to deactivate virus checks at sending emails.
Problem was solved … and there is no reason to check mails during sending from a clean system.
