SpIDer Guard

SpIDer Guard performs constant real-time scanning of the file system, checks files as they are modified or saved, thereby protecting the system against security threats.

SpIDer Guard settings for computers running macOS are available in the SpIDer Guard for workstations section, for macOS Server—in the SpIDer Guard for servers section.

•Set the Use heuristic analysis flag to use heuristic analysis for detecting unknown threats.

•Set/clear the Enable SpIDer Guard for macOS (for servers—Enable SpIDer Guard for macOS Server) flag to enable/disable SpIDer Guard.

•In the Scanning time of one element field, specify the maximum time for scanning a file. Value 0 means that time to scan one file is unlimited.

Increasing the time for scanning a single file may slow down the computer and increase the overall scanning time.

In this section, select actions that will be applied automatically to computer threats detected by SpIDer Guard depending on their types:

•Cure, move to quarantine if not cured. Instructs to restore the original state of the object before infection. If the object is incurable, or the attempt of curing fails, this object is moved to quarantine. The action is available only for objects infected with a known virus that can be cured except for the Trojan programs and files within complex objects.

•Cure, delete if not cured. Instructs to restore the original state of the object before infection. If the object is incurable, or the attempt of curing fails, this object is deleted. The action is available only for objects infected with a known virus that can be cured except for the Trojan programs and files within complex objects.

•Move to quarantine. This action moves a detected threat to a special folder that is isolated from the rest of the system.

•Delete. It is the most effective way to remove all types of threats. This action implies full deletion of a dangerous object.

•Ignore. No actions are applied to the object. Notifications are not displayed.

The default settings are optimal for most cases. Do not change them unnecessarily.

In this section, specify the maximum nesting level for containers being checked. If the nesting level is higher than the specified value, the container will be ignored when scanning. Value 0 means that nested objects will not be checked.

In the Maximum compression ratio field, specify the maximum compression ratio for compressed objects (a ratio of source object size to compressed size). If compression ratio of an object is greater than the specified value, the object will be ignored when scanning.

In this section, specify paths to files and folders which will be excluded from scanning by SpIDer Guard.
