A common technique of concealing viruses and other malware is to implant them in compound files, such as archives or databases. To detect viruses and other malware that are hidden in this way, the compound file has to be unpacked, which may slow down scanning. You can limit the set of compound files to be scanned, thus speeding up scanning.
To configure scanning of compound files:
Open Kaspersky Security Center Administration Console.
In the Managed devices folder of the console tree, open the folder with the name of the administration group to which the relevant protected virtual machines belong.
In the workspace, select the Tasks tab.
Select a Light Agent for Windows virus scan policy in the list of policies and open the Properties: <Task name> window in one of the following ways:
By double-clicking.
Right-click to bring up the context menu of the task and select Settings.
By clicking the Configure task settings link is located on the right of the list of tasks in the section with task settings.
In the window of Light Agent for Windows virus scan task properties, select the Settings section in the list on the left.
The task settings will appear in the right part of the window.
In the Security level section, click the Settings button.
The Virus Scan window opens.
In Virus scan window on the Scope tab, in the Scan of compound files section, specify which compound files you want to scan: archives, self-extracting archives, embedded OLE objects, mail format files, or password-protected archives by selecting the corresponding check boxes.
Click the Additional button.
The Compound files window opens.
In the Size limit section, do one of the following:
If you want the application to unpack large compound files, clear the Do not unpack large compound files check box.
If you do not want the application to unpack large compound files, select the Do not unpack large compound files check box and specify the required value in the Maximum file size field.
A file is considered large if its size exceeds the value in the Maximum file size field.
The application scans large files that are extracted from archives, regardless of whether the Do not unpack large compound files check box is set.
