Enable Smart optimization

With Smart Optimization enabled, settings are optimized to ensure the most efficient level of scanning without compromising scanning speed. The various protection modules scan intelligently, making use of different scanning methods. Smart Optimization is not rigidly defined within the product. The ESET Development Team is continuously implementing new changes which are then integrated into ESET Cyber Security Pro through regular updates. If Smart Optimization is disabled, only the user-defined settings in the ThreatSense core of the particular module are applied when performing a scan.

Scan alternative data stream (On-demand scanner only)

Alternate data streams  used by the file system are file and folder associations which are invisible to ordinary scanning techniques. Many infiltrations try to avoid detection by disguising themselves as alternative data streams.
