How do I turn off Avast email signature for my whole organisation?

One handy feature in Crossware Mail Signature helps you remove email footers from all business correspondence, company wide.

This method is not necessary if you have central management of Avast on one device and can remove the email footer text in one go, but is very useful for companies where people use different versions of Avast or where only some people use Avast.

Crossware Mail Signature can help you set up a company-wide email modifier (allowing you to find and replace values) which will automatically remove the Avast footer.

You must be set up with a Crossware Mail Signature trial or the paid product to try this. Visit our Free Trial page to start a free 30 day trial of Crossware Mail Signature for Office 365, Microsoft Exchange or IBM Domino.


  1. Once you’ve logged into your Crossware Mail Signature trial or paid subscription, go to Signature Designer > Admin > Email Modifiers:


  1. Click on Create New:
  2. Give your Modifier a name, e.g. Avast Email Footer Removal and a description so you can find your modifier again in the future.
  3. Click Save.


You will now be able to add your “strings,” which is the text that you’d like to modify. In this case it will be the text that Avast is inserting in each email.


Click Add and fill out the dialogue box fields with this text. We have included (and recommend you include) the messages that will appear from all different versions of Avast. Unless you are sure that everyone in your company is using one up-to-date version of Avast, it is best to include a string for each in your modifier.

See the following image and instructions:


  1. Under ‘Description’ – specify the version of Avast
  2. Under ‘Field to Modify’ – Body is checked (since we want to find this text string in the body text of each email)
  3. Under ‘Find’ – list the string of words we want to remove.
  4. Under ‘Replace’ – leave this blank, as we want to replace the ‘Find’ string with a blank space.


  1. Save this string.
  2. Repeat for text that other versions of Avast might be adding to your company’s emails.



Avast 2016


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



Avast 2014 / 2015


This email has been checked for viruses by Avast antivirus software



Avast 8 or older


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


Your modifier summary should look like the image below once all your strings are saved:

Send test emails from various user accounts to ensure the modifier is working and all mentions of Avast are gone. You can always add more strings if you find one is missing.

You can now relax knowing that your users are no longer having to manually remove the footer text or appear unprofessional to recipients with our guide for easy instructions to uninstall the Avast email signature.
