Filtering Agent Known Antivirus Issues

Currently, there are known issues with the following:


  • Avast Antivirus will prevent you from installing the agent unless you disable it before running the installer file.
    • Once you have the agent fully installed, you can then re-enable Avast and everything will run as expected.
  • If you find you're unable to load web pages, you may need to go into the Firewall settings and change the network type from "Public" to "Private".


  • BitDefender Antivirus has been known to try to block the Filtering Agent installations. If this problem occurs for you, please add ZorusInstaller.exe to your Antivirus, Firewall, and Advanced Threat Defense exception lists.
-Cylance Antivirus:
  • Cylance has been known to pick up the Zorus Agent Updater as a potential threat. If this happens, you can put ZorusAgentUpdater.exe into your safe/exclusion list so Cylance will not interfere with future updates.


***If you have ESET installed and are unable to load websites, please follow this link for the steps needed to configure it.

-Kaspersky Cloud AV:

  • Kaspersky's Cloud AV product has been known to flag our agent as potentially malicious which we've confirmed with them is indeed a false positive.
    • The cause of this is related to the AMSI Protection in the application's default security profile settings which need to be disabled.

  • McAfee Antivirus is known to interfere with the agent and an endpoint's connectivity to the internet.
    • If you have McAfee installed on your endpoint, you may need to add an exception for the agent, service, and updater so this doesn't happen.
      • You can do this by clicking the settings icon, and adding the the ZorusDeploymentService.exe, ZorusDeploymentAgent.exe, and ZorusAgentUpdater.exe (located in your installation folder, e.g: C:\Program Files\Zorus Inc\Archon Agent\Zorus Deployment Agent) to the "Excluded Files" in the "Real-Time Scanning" setting and then adding/saving those same files in the Firewall setting called, "Internet Connections for Programs".
      • Additionally, you will need to change the access settings to allow all incoming and outgoing traffic through. To do this, follow the steps below.

First, click on one of the Zorus .exe files you added from the previous step and click edit.


Next, scroll down to the "Access" section, click the drop-down menu under "Incoming and outgoing" and choose "Open to all devices".

Then click "Save".


Do this for all Zorus files (ZorusDeploymentAgent, ZorusAgentUpdater, and Zorus Deployment Service).

After you've followed these steps, McAfee Antivirus should no longer interfere with your internet connection and you should be able to browse and use the web as you would normally.
