CONFIGURING MAIL ANTI-VIRUS
Kaspersky Internet Security allows scanning email messages for dangerous objects by using Mail Anti-Virus. Mail
Anti-Virus starts when the operating system is started and remains constantly in the RAM of the computer, scanning all
email messages that are sent or received over the POP3, SMTP, IMAP, and NNTP protocols, as well as via encrypted
connections (SSL) over the POP3, SMTP, and IMAP protocols.
By default, Mail Anti-Virus scans both incoming and outgoing messages. If necessary, you can enable scanning of
incoming messages only.
To configure Mail Anti-Virus:
1. Open the main application window.
2. Click the button in the lower part of the window.
The Settings window opens.
3. In the left part of the window, in the Protection section, select the Mail Anti-Virus component.
The Mail Anti-Virus settings are displayed in the window.
4. Make sure that the switch in the upper part of the window that enables / disables Mail Anti-Virus, is enabled.
5. Select a security level:
Recommended. If you select this security level, Mail Anti-Virus scans both incoming and outgoing
messages and scans attached archives.
Low. If you select this security level, Mail Anti-Virus scans incoming messages only, without scanning
attached archives.
High. If you select this security level, Mail Anti-Virus scans both incoming and outgoing messages and
scans attached archives. When the security level is set to High, the application uses heuristic analysis with
the Deep scan level of detail.
6. In the Action on threat detection drop-down list, select the action that you want for Mail Anti-Virus to perform
when an infected object is detected (for example, disinfect).
If no threats are detected in an email message, or if all infected objects have been successfully disinfected, the message
becomes available for further access. If the component fails to disinfect an infected object, Mail Anti-Virus renames or
deletes the object from the message and adds a notification to the message subject line, stating that the message has
been processed by Kaspersky Internet Security. Before deleting an object, Kaspersky Internet Security creates a backup
copy of it and places this copy in Quarantine (see the section "Restoring an object deleted or disinfected by the
application" on page 46).
