Hi lolnerddie,
This plugin does not contain a virus, and we believe this is a false positive caused by one of the libraries this plugin was using.
We have since removed most of the libraries this plugin uses, and released a new version, which does not get falsely flagged.
If you don't believe us, the source code for this plugin is available at
https://github.com/HyperaDev/UltraStaffChat - You can audit this source code, and even build the plugin from scratch if you wish to.
We hope that you will reconsider this review, as this was completely out of our control.
Sorry for the inconvenience.
Have a great day!
