Folks, I just stomped into this short notice from gHacks, and I'd like to share it with you. Though I'm not an Avast user (like the author, I'm also using Kaspersky Free), I thought some of you may benefit from his findings. There are a step-by-step procedure description, screenshots, and even a video. You may reach the article from the link below. Beware of line breaks. <https://www.ghacks.net/2019/07/18/how-to-disable-the-email-signature-in-avast-free-antivirus> Enjoy!
