So it’s installed on your personal systems on purpose but is it installed on everyone of your clients ? as like I mentioned it has to be downloaded separately - only the connector module is preinstalled.

If your clients have all downloaded via the connector module then you could send them an email explaining how to remove if they don’t wish to have the feature, it’s a very easy process to remove if unwanted and it doesn’t require a custom install being that avast is already installed " use the change feature"
