Update (July 28, 2021) - Our developers have released the updated build of our Antivirus for On-Premise customers earlier today. If you require assistance in updating to the latest release please reach out to the support team via email to support@faronics.com for assistance.

Update (July 27, 2021) - Our developers have pushed an updated build of our Antivirus software to the Deep Freeze Cloud and Faronics Deploy services to resolve this issue. We are working on getting an updated build of the AV software released for our customers who run an On-Premise version of Faronics Antivirus shortly.

Update (July 20th, 2021) - Our developers have identified the issue in the update to Antivirus 4.31 and will be issuing a patch to address this soon. We will provide a further update here once that patch is released. 

We have become aware of an issue that can occur during the updating Faronics Antivirus to the recent 4.31 release that we pushed to production earlier this week.

Customers seeing this issue may see client machines not turning on the Active Protection component of the antivirus solution.

Our developers are investigating this issue. We will post updates here as we receive more information from them. The issue appears to be only impacting upgrades and not new installations, or reinstallations of the product.

For customers who have encountered this issue, the problem can be resolved following the process below;

  1. Disable any Faronics products installed on the system.
  2. Rename the copy of the file gzflt.sys located at the following location: C:\Windows\System32\drivers\gzflt.sys
  3. Copy the gzflt.sys file from C:\ProgramData\Faronics\AntiVirusSpace\AVB\gzflt.sys to C:\Windows\System32\drivers\
  4. Restart the computer.
  5. Enable Active Protection.
  6. Alternatively uninstalling and reinstalling the Faronics Antivirus component of our software is currently appearing to resolve this issue.

If you have not encountered this issue we recommend that you hold off on the upgrade to our 4.31 release of the antivirus software until development has determined the cause of this issue and implemented appropriate fixes in the product to address the upgrade scenario.

For our Deep Freeze Cloud Customers and users of Faronics Deploy, we are implementing a block on this update to prevent the update from deploying until we have a fix in place. Customers using our on-premise software should hold off on upgrading client workstations further until our developers have reviewed the issue and provided a workaround or updated build to address this issue.

If you have encountered this issue and require assistance in getting the issue resolved please feel free to reach out to our support team. Support is reachable either via email to support@faronics.com or via our support portal located at https://www.faronics.com.
