Without knowing any details we can’t help.
What OS/SP ?
What exact version of avast ?
Any other security software installed ? (or was there)
What email client ?
What is the email server ?
OS-Win 8.1 pro/win10pro
avast pro version-11.1.2241
Only avast pro
Mozilla Thunderbird-Postbox
DISABLE (Mail Shield) email works great
Is the avast certificate imported in Thunderbird ?
If not do so and see if the problem is solved.
If that doesn’t solve things, perform a clean installation of this version:
