Today we wanted to install the Avast Ultimate Business Client on one of our machines. The Online-Installer never finished, because the download got blocked by the firewall. Below you see screenshots from Secureporter and the Eventlog.

I hope this is the right way to report false positives. I could not find any offical form for this.

Kind regards,

Michael

    Hi @Dexta

    To avoid false positive detections by Anti-Malware in the Nebula firewall, please add the file name to the Allow list of the Anti-Malware (path: Site-wide > Configure > Firewall > Security service). You can find the file name in your Nebula firewall event log. Based on the screenshot you provided, the file name is “5f195612-384a-48ea-8408-b4ede9dc56bb”.

    For more details, please refer to this article:
