Real-time file system protection

Real-time file system protection controls all antivirus-related events in the system. All files are scanned for malicious code when they are opened, created, or run on your computer. Real-time file system protection is launched at system startup.

CONFIG_AMON

By default, Real-time file system protection launches at system start-up and provides uninterrupted scanning. In special cases (for example, if there is a conflict with another real-time scanner), real-time protection can be disabled by disengaging Start Real-time file system protection automatically in Advanced setup under Real-time file system protection > Basic.

Media to scan

By default, all types of media are scanned for potential threats:

Local drives – Controls all system hard drives.

Removable media – Controls CD/DVDs, USB storage, Bluetooth devices, etc.

Network drives – Scans all mapped drives.

We recommend that you use default settings and only modify them in specific cases, such as when scanning certain media significantly slows data transfers.

Scan on

By default, all files are scanned upon opening, creation, or execution. We recommend that you keep these default settings, as they provide the maximum level of real-time protection for your computer:

File open – Enables or disables scanning when files are opened.

File creation – Enables or disables scanning when files are created.

File execution – Enables or disables scanning when files are run.

Removable media access – Enables or disables scanning triggered by accessing particular removable media with storage space.

Computer shutdown – Enables or disables scanning triggered by computer shutdown.

Real-time file system protection checks all types of media and is triggered by various system events such as accessing a file. Using ThreatSense technology detection methods (as described in the ThreatSense engine parameter setup section), Real-time file system protection can be configured to treat newly created files differently than existing files. For example, you can configure Real-time file system protection to more closely monitor newly created files.

To ensure a minimal system footprint when using real-time protection, files that have already been scanned are not scanned repeatedly (unless they have been modified). Files are scanned again immediately after each virus signature database update. This behavior is controlled using Smart optimization. If this Smart optimization is disabled, all files are scanned each time they are accessed. To modify this setting, press F5 to open Advanced setup and expand Antivirus > Real-time file system protection. Click ThreatSense parameter > Other and select or deselect Enable Smart optimization.
