Main functionality

On-demand scanner

The On-demand scanner can be started by a privileged user (usually a system administrator) through the command line interface, the web interface 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.

On-access scanner

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.
