How to Disable / Remove Avast Email Signature


Want to permanently disable or remove the Avast email signature from all outgoing emails? You’ve come to the right place!

When you install Avast, by default, there will be an email signature setting which is turned on which inserts one of the following messages to all of your outgoing emails:


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

“This email has been checked for viruses by Avast antivirus software.”

“This email is free from viruses and malware because Avast Antivirus protection is active.”

The message is usually appended at the bottom of all outgoing emails if you’re using Outlook, Thunderbird or any other email client that is installed on your PC. It’s also inserted if you’re using Gmail, Yahoo Mail or any other webmail provider via your web browser.

This can be an annoying feature when you don’t want to tell each and every email recipient that the message has been scanned for viruses.

How to Disable Avast Email Signature from Outgoing Emails

Step 1:

Right-click on the Avast icon in the system tray and click “Open Avast user interface”.


Step 2:

Click on Menu in the top right corner, and then click Settings.

If you cannot find Menu, you may see a settings style gear or cog icon instead.


Step 3:

On the left-hand side, ensure you are in the General section.

Find the setting for “Enable Avast email signature” and uncheck it.


Step 4:

Click the OK button to close out of the settings.

Restart your email software and also your web browser.

The Avast email signature should no longer be appended to your outgoing emails.

  1. How do I get rid of this?

    “This email has been checked for viruses by Avast antivirus software.

    I blocked this a few years ago and now I can’t figure it out. If I right-click on the taskbar icon, I don’t get what they show in the picture.

    In that “General” area

    Nothing happens when I click on it.


    It doesn’t look at all like what they show on the webpage. OK, I found

    “On the left-hand side, ensure you are in the General section.”

    “Find the setting for “Enable Avast email signature” and uncheck it.”

    I can’t find it.

    All that is available is the language choice.

  2. On the latest version of AVAST (20.4.2410 [build 20.4.5312.577]), the option is located under


    Under “Configure Shield Settings” section select “Mail Shield” tab, and UNCHECK “Add Signature To The End Of Sent Emails”

    1. THANK YOU!!!!! This has been driving me nuts & I only could find the other instructions. It was so frustrating. Thank you, thank you, thank you!!

  3. on my avast , under core shield it does not show any option of turning the email signature, only if i want to turn the mail shield on or off

    1. The place to turn off the signature in emails has been moved it is now in:
      Menu > Settings > Protection > Core Shields

      Then scroll down and under ‘Configure shield settings’ select the ‘Mail Shield’ tab.
      Uncheck ‘Add a signature to the end of sent emails’

  4. Hi Gordan and readers!

    Either the process is different because I have Avast Premium Security and your screenshots show “Avast Free Antivirus” or the process to update this setting has simply changed.

    To remove the email signature from Avast on Windows as of February 2021, the steps are now as follows:

    1. Open Avast user interface
    2. Select “Menu” (in top right) >> then “Settings”
    3. Select “Protection” (on left) >> then “Core Shields” in left-hand sub-menu
    4. Scroll down & under “Configure shield settings” select the “Mail Shield” tab on the right
    5. Uncheck the box for “Add a signature to the end of sent emails”

    Hope this helps!
