ESET's state-of-the-art scanning engine has unsurpassed scanning speed and detection rates combined with a tiny footprint that makes ESET Endpoint Antivirus for Linux (eeau) the ideal choice for any Linux desktop meeting the system requirements.

Main functionality is covered by the On-demand scanner and On-access scanner.

The On-demand scanner can be started by a privileged user (usually a system administrator) through the command line interface, ESET Security Management Center or by the operating system's automatic scheduling tool (e.g., cron). The term On-demand refers to file system objects being scanned by either user or system demand.

The On-access scanner is invoked whenever a user and/or operating system attempts to access file system objects. This also clarifies the use of the term On-access; because a scan is triggered by any attempt to access file system objects.
