By default, Real-time file system protection launches at system startup and provides uninterrupted scanning. In special
cases (e.g., if there is a conflict with another real-time scanner), real-time protection can be terminated by deselecting
Start Real-time file system protection automatically.
Media to scan
By default, all types of media are scanned for potential threats:
Local drives – Controls all system hard drives.
Removable media – Diskettes, CD/DVDs, USB storage devices, etc.
Network drives – Scans all mapped drives.
We recommend that you keep the default settings and only modify them in specific cases, such as when scanning
certain media significantly slows data transfers.
Scan on (Event-triggered scanning)
By default, all files are scanned upon opening, creation or execution. We recommend that you keep the default
settings, as these provide the maximum level of real-time protection for your computer:
File open – Enables or disables scanning of opened files.
File creation – Enables or disables scanning of newly created or modified files.
File execution – Enables or disables scanning of executed files.
Removable media access – Enables or disables scanning triggered by accessing particular removable media with
storage space.

Additional ThreatSense parameters for newly created and modified files – The probability of infection in newly-
created or modified files is comparatively higher than in existing files. For this reason, the program checks these files
with additional scanning parameters. Along with common signature-based scanning methods, advanced heuristics are
used which can detect new threats before the virus signature database update is released. In addition to newly-created
files, scanning is also performed on self-extracting files (.sfx) and runtime packers (internally compressed executable
files). By default, archives are scanned up to the 10th nesting level and are checked regardless of their actual size. To
modify archive scan settings, deselect the Default archive scan settings option.
Additional ThreatSense parameters for executed files – By default, advanced heuristics are not used when files are
executed. However, in some cases you may want to enable this option (by checking the Advanced heuristics on file
execution option). Note that advanced heuristics may slow the execution of some programs due to increased system
