Todd,
Thanks for reporting this.
Our releases are always checked for viruses and to our knowledge there are no known exploits though we are always happy to review reports from users.
The CodeMix Engine runs the external Node process and is expected, and is not an exploit. This is a generic warning about a program running external Javascript, but in our case, very intended and necessary.It is a false positive and you can report the same.
Hope this helps. Please let us know if you have any further questions.
