InterWorx uses the ClamAV software package to detect software threats coming in through the email system.
SMTP level virus scanning allows ClamAV to scan email as it comes in to the SMTP server. This allows ClamAV to stop threats before they ever reach the system. If ClamAV detects a virus it will cause the SMTP service to reject the message.
If the ClamAV and Freshclam daemons are stopped when you enable SMTP virus scanning, they will be automatically started.
The stop and start procedures that follow assume that SMTP virus scanning is enabled.
Stop the ClamAV Service
If you have SMTP virus scanning enabled and you stop the ClamAV service, mail delivery will stop until the ClamAV service is restarted or SMTP virus scanning is disabled.
The stop and start procedures that follow assume that SMTP virus scanning is enabled. Freshclam is the automatic virus definition update service used by ClamAV. If this is enabled, ClamAV will always have the most recent virus definitions.
Stop the Freshclam Service
