Other options

Following are other options you can specify:

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, using different scanning methods. Smart Optimization is not rigidly defined within the product. ESET is continuously implementing new changes that are 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 that are invisible to ordinary scanning techniques. Many infiltrations try to avoid detection by disguising themselves as alternative data streams.
