Most antivirus products will be detected by Metadefender Core, but this does not necessarily mean they are compatible. You can check to see that yours is on our Compatible Engines list.
There are a number of possible causes for Customer Licensed Engines to return a "Failed to Scan" error. These include:
You are not running the most up to date version of Metadefender Core. The Compatible Engines list is only valid for the latest version of Metadefender Core
You have not properly configured the antivirus to work with Metadefender Core. This is usually just a matter of excluding Metadefender's Core installation and temp directory from the antivirus engine's real time protection.
If you have done all this and you are still receiving the error, please submit a support ticket via the OPSWAT Portal.
