The Kaspersky Security functionality described in this section is available only if the application is installed on a virtual machine with a Windows desktop or server operating system.

Mail Anti-Virus scans incoming and outgoing email messages (hereinafter also "messages" or "mail") for viruses and other malware. The Mail Anti-Virus runs when the application starts; it persists in the VM RAM to check messages received via POP3, IMAP and NNTP, and messages sent via SMTP.

Mail Anti-Virus can scan the messages, that are sent or received via the protocols, that ensure encrypted data transfer.

Mail Anti-Virus intercepts and scans each e-mail message that you receive or send. If no threats are detected in the message, it becomes available to the user.

If Mail Anti-Virus detects a threat in the message during scanning, Kaspersky Security assigns one of the following status labels to this message to designate the type of object detected (for example: virus, Trojan program).

The application then blocks the infected message and performs the action defined in the Mail Anti-Virus settings.

If a message sent via SMTP is found to contain a threat, the message is blocked regardless of the action chosen.

Mail Anti-Virus interacts with mail clients installed on the protected virtual machine. An embeddable extension is available for the Microsoft Office Outlook mail client that lets you fine-tune the message scan settings. The Mail Anti-Virus extension is embedded in the Microsoft Office Outlook mail client during installation of Kaspersky Security.
