If the answer to you is simple then the responsive answer in reply is also simple! teach your clients to always read things correctly, there is no trickery! they simply need to read what is laid before them and don’t click on links or offers if they are not wanted ( Simple :slight_smile: )

If your clients are failing on this process there are probably far more serious issues with there systems as they probably have a bundle of addons and toolbars that come with installers of most software these days.
