Configuring the task settings

To configure settings of an existing On-Demand Scan task:

1. Open the On-Demand Scan task properties.
2. Select the Options section.
3. Clear or select the Use Heuristic Analyzer check box.
   

   This check box enables / disables Heuristic Analyzer during object scanning.

   If the check box is selected, Heuristic Analyzer is enabled.

   If the check box is cleared, Heuristic Analyzer is disabled.

   The check box is selected by default.

4. If necessary, select the level of analysis using the Heuristic analysis level drop-down list.
   

   The heuristic analysis level sets the balance between the thoroughness of searches for threats, the load on the operating system's resources and the time required for scanning.

   The following scanning sensitivity levels are available:

   • Light. Heuristic Analyzer performs fewer instructions within executable files. The probability of threat detection in this mode is somewhat lower. Scanning is faster and less resource-intensive.
   • Medium. Heuristic Analyzer performs the number of executable file instructions recommended by Kaspersky experts.

   This level is selected by default.

   • Deep. Heuristic Analyzer performs more instructions within executable files. The probability of threat detection in this mode is higher. Scanning uses more system resources, takes more time, and can produce a higher number of false alarms.

   The setting is available if the Use heuristic analyzer check box is selected.

5. In the Integration with other components section, configure the following settings:
   • Select the Apply Trusted Zone check box, if you want to exclude objects added to the Trusted Zone list from the scan scope of the task.
     

     This check box enables / disables use of the Trusted Zone for a task.

     If the check box is selected, Kaspersky Security for Windows Server adds file operations of trusted processes to the scan exclusions configured in the task settings.

     If the check box is cleared, Kaspersky Security for Windows Server disregards the file operations of trusted processes when forming the protection scope for the task.

     The check box is selected by default.

   • Select the Use KSN for scanning check box, if you want to use Kaspersky Security Network cloud services for the task.
     

     This check box enables / disables the use of Kaspersky Security Network (KSN) cloud services in the task.

     If the check box is selected, the application uses data received from KSN services to ensure the application responds more quickly to new threats and reduce the likelihood of false positives.

     If the check box is cleared, the On-Demand Scan task does not use KSN services.

     The check box is selected by default.

   • To assign Low priority to the working process in which the task will be executed, select the Perform task in background mode check box.
     

     The check box modifies the priority of the task.

     If the check box is selected, the task priority in the operating system is reduced. The operating system provides resources for performing the task based on the CPU load and protected device file system load from other Kaspersky Security for Windows Server tasks and other applications. As a result, task performance will decrease during periods of increased loads and will increase at lower loads.

     If the check box is cleared, the task will start and run with the same priority as the other Kaspersky Security for Windows Server tasks and other applications. In this case, the task performance increases.

     The check box is cleared by default.

     By default, the working processes in which Kaspersky Security for Windows Server tasks are run have Medium (Normal) priority.

   • To use the created task as a Critical Areas Scan task, select the Consider task as critical areas scan check box.
     

     The check box changes the task priority: it enables or disables logging of the Critical Areas Scan event and refreshing of the device protection status. Kaspersky Security Center evaluates the security rating of the protected device(s) using the performance results of tasks with the Critical Areas Scan status. The check box is not available in the properties of local system and custom tasks of Kaspersky Security for Windows Server. You can edit this setting only on the side of Kaspersky Security Center.

     If this check box is selected, Administration Server logs completion of Critical Areas Scan tasks and refreshes the device protection status based on the task execution results. The scan task has high priority.

     If the check box is cleared, the task is run with low priority.

     The check box is cleared by default for custom On-Demand Scan tasks.
