Scan compound files that are attached to messages

You can enable or disable scanning of compound files attached to messages, limit the maximum size of message attachments to be scanned, and limit the maximum message attachment scan duration.

To use Kaspersky Security Center to configure scan of compound files attached to messages:

  1. Open Kaspersky Security Center Administration Console.
  2. 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.
  3. In the workspace, select the Policies tab.
  4. Select a Light Agent for Windows policy in the list of policies and open the Properties: <Policy name> by double-clicking.
  5. In the policy properties window, select the Mail Anti-Virus section in the list on the left.
  6. In the right part of the window, in the Security level section, click the Settings button.
  7. In the Mail Anti-Virus window that opens, on the General tab, in the Scan compound files section, perform the following:
    • If you want Mail Anti-Virus to skip archives that are attached to messages, clear the Scan attached archives check box.
    • If you want Mail Anti-Virus to skip attached archives that are larger than a specified number of megabytes, select the Do not scan archives larger than N MB check box. If you select this check box, specify the maximum archive size in the field next to the name of the check box.
    • If you want Mail Anti-Virus to skip attached archives that take more than a specified number of seconds to scan, select the Do not scan archives for more than N sec check box. If you set this check box, specify the maximum archive scan time in the field that is opposite the name of the check box.
  8. Click OK in the Mail Anti-Virus window.
  9. Click the Apply button.

To use the local interface to configure scan of compound files attached to messages:

  1. On the protected virtual machine, open the application settings window.
  2. In the left part of the window, in the Anti-Virus protection section, select Mail Anti-Virus.

    In the right part of the window, the Mail Anti-Virus component’s settings are displayed.

    If the settings in the local interface are not available, this means that the values of settings defined by the policy are used for all protected virtual machines of the administration group.

  3. Complete steps 6–8 of the previous instructions.
  4. To save changes, click the Save button.
