Filme video editor malware found!

After I update imyfone filme (url removed) video editor to the latest version, AVG detects that some DLL files contain in this software infected malware(win64:DangerousSig [Trj]). Now I can't execute the filme video editor. I already sent these files to the AVG threat lab.

I submitted a false positive request. But I cannot get a screenshot of the notification because the notification is displayed during the first time I run the software after the installation and then the infected files automatically moved to the quarantine. Now I can only see an error message like this.User-added image
