How to disable Avast email signatures

Avast Antivirus is a great antivirus however if your recently start seeing “This email has been sent from a virus-free computer protected by Avast” message in your emails, it might be little bit obtrusive.

Avast email signatures has been Avast feature since long time ago. For years, it has been working in email clients (eg. Outlook, Thunderbird..) but with recent update it is working also in web-based emailing. So if you are using Gmail or Yahoo in your browser like I do, Avast inserts this signature to your emails:

This email has been sent from a virus-free computer protected by Avast.

UPDATE (5/3/2015): Recently, Avast changed email signature to less obtrusive version:
