Why does Mobile Security Client offer plaintext http download links?

Hi there! Would anybody have an idea how to avoid the awkward feature in mobile security installation offering download links in _plaintext_? I have asked about this from my account manager but haven't received an answer. Have the developers at F-Secure not heard about TLS and the little green lock in in your browser ? Embarrassing. My users cannot believe that this is a real message from F-Secure and they refuse to use the link. Could the download link be somehow configured to use TLS?
