Identified

We have identified the cause of the issue affecting the ClamAV service. A recent malware signature update introduced an invalid entry in the ClamAV signature database, which can prevent the clamd service from restarting successfully.

Our team is currently applying a signature database refresh on affected servers to remove the invalid entry and restore normal operation of the ClamAV service.

We are currently applying this fix across all affected servers and will provide another update once the process is completed.

Investigating

We are currently investigating an issue affecting the ClamAV service, where clamd restarts may fail due to a problematic signature update. Our System Engineering team is actively working to identify the root cause and implement a fix.

This issue may affect Maldet scans and cause mail delivery failures if the ClamAV service is not running.
