Exclusions enable you to exclude objects from the detection engine. To ensure that all objects are scanned, we recommend only creating exclusions when it is absolutely necessary. Situations, where you may need to exclude an object, might include scanning large database entries that would slow your computer during a scan or software that conflicts with the scan.

Performance exclusions—exclude files and folders from scanning. Performance exclusions are useful to exclude file-level scanning of gaming applications or when causing abnormal system behavior or increased performance.

Detection exclusions—exclude objects from detection using the detection name, path, or its hash. Detection exclusions do not exclude files and folders from scanning as performance exclusions do. Detection exclusions exclude objects only when they are detected by the detection engine and an appropriate rule is present in the exclusion list.

Not to be confused with other types of exclusions:

Process exclusions—All file operations attributed to excluded application processes are excluded from scanning (may be required to improve backup speed and service availability),

Excluded file extensions,

HIPS exclusions,

Exclusion filter for Cloud-based protection.
