Remove Winzip Branding from Mails with Encrypted Attachements

As of Winzip 29 when you send a mail with an encrypted attachment it's adding Winzip branding to the outgoing e-mail body. In my enterprise this is unacceptable from both a business and compliance perspective. We logged aticket to support who stated that this was the intention also in previous versions of the product but a bug prevented it occuring. We are looking at alternative products now as there is no commitment from suport to address this
