The Mail Threat Protection component scans the attachments of incoming and outgoing email messages for viruses and other threats. The component also scans messages for malicious and phishing links. By default, the Mail Threat Protection component permanently resides in the computer's RAM and scans all messages received or sent using the POP3, SMTP, IMAP, or NNTP protocols, or the Microsoft Office Outlook mail client (MAPI). The component provides computer protection with the help of anti-virus databases, the Kaspersky Security Network cloud service, and heuristic analysis.
The Mail Threat Protection component does not scan messages if the mail client is open in a browser.
When a malicious file is detected in an attachment, Kaspersky Endpoint Security renames the message subject as follows: [Message is infected] <message subject> or [Infected object deleted] <message subject>.
This component interacts with mail clients installed on the computer. For the Microsoft Office Outlook mail client, an extension with additional parameters is provided. The Mail Threat Protection extension is embedded in the Microsoft Office Outlook mail client during installation of Kaspersky Endpoint Security.
