Virus Scan is a one-time full or custom scan of files on the computer performed by the application. The application can perform several virus scan tasks at the same time.
By default, the application creates one standard virus scan task – full scan. The application scans all objects located on local drives of the computer, as well as all mounted and shared objects that are accessed via the Samba and NFS protocols with the recommended security settings.
During a full disk scan, the computer processor will be busy. It is recommended to run the full scan task when the business is idle.
You can also create virus scan user tasks.

Task priority |
In this group of settings you can select the task priority:
|
Scan archives |
This check box enables or disables scan of archives. If the check box is selected, the application scans archives. To scan an archive, the application has to unpack it first, which may slow down scanning. You can reduce the archive scan time by configuring the Skip object if scan takes longer than (sec) and Skip objects larger than (MB) settings in the General scan settings section. If the check box is cleared, the application does not scan archives. The check box is selected by default. |
Scan SFX archives |
This check box enables or disables self-extracting archive scans. Self-extracting archives are archives that contain an executable extraction module. If the check box is selected, the application scans self-extracting archives. If the check box is cleared, the application does not scan self-extracting archives. This check box is available if the Scan archives check box is unchecked. The check box is selected by default. |
Scan mail databases |
This check box enables or disables scan of mail databases of Microsoft Outlook, Outlook Express, The Bat!, and other mail applications. If the check box is selected, the application scans mail database files. If the check box is cleared, the application does not scan mail database files. This check box is cleared by default. |
