Avast Logo and website Appearing in my email messages

I recently sent an email and discovered belatedly that the Avast logo and website appears right smack in the middle of my message.
This is completely unacceptable. It totally disrupts the message. Very disappointed and annoying to see this
I tried to contact Avast, but it is impossible to contact them about this.
