Concerned about file warning from Wordfence

I got the following warning on one of the files in my BB folder, should I be concerned or is this file there intentionally?:

This file may contain malicious executable code: /home/barrys15/public_html/wp-content/plugins/bb-plugin/includes/vendor/infusionsoft/xmlrpc-3.0/lib/
Filename: wp-content/plugins/bb-plugin/includes/vendor/infusionsoft/xmlrpc-3.0/lib/
File type: Not a core, theme or plugin file.
Issue first detected: 14 hours 2 mins ago.
Severity: Critical
Status New
This file is a PHP executable file and contains the word ‘eval’ (without quotes) and the word ‘base64_decode(’ (without quotes). The eval() function along with an encoding function like the one mentioned are commonly used by hackers to hide their code. If you know about this file you can choose to ignore it to exclude it from future scans.

Hey Jason,

That has already been discussed on the thread below. Let us know if you need anything further!
