Background information about the issue
Antivirus software checks not only the authenticity of the software but also its behavior.
Our software is distributed by adding plugins to Autocad or Revit and this behavior that modifies folders that are outside of the installation is considered as a Trojan behavior, and that is why it alerts users as a Trojan. Nevertheless; the behavior is completely normal, especially to apply updates.
The antivirus manufacturers recommended that when this behavior is completely under control, the end-user can add some exceptions or exclusions in the files to scan.
