Gmail recently changed their virus scanner, and are now reporting false positives for files produced in Mac Verbatim. There is unfortunately nothing I can do - Gmail is in complete control of what they mark as a virus and what they don’t. The files being sent do not contain any macros or code (all code lives inside the master template on your computer), so it’s impossible for them to have a virus. That is, there’s no way to modify Mac Verbatim to avoid this issue.
Your best bet is to use something other than email to transfer your files, or to copy and paste the contents of your verbatim file into a new non-Verbatim blank Word document before sending via email.
