Kaspersky Free

Scanning email messages

Kaspersky Free 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 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 Free. Before deleting an object, Kaspersky Free creates a backup copy of it and places a copy in Quarantine.

If Kaspersky Free detects the password for the archive in the message text during scanning, the password is used to scan the contents of that archive for malware. The password is not saved. The archive is unpacked before scanning. If the application crashes while unpacking the archive, you can manually delete the files that are unpacked at the following path: %systemroot%\temp. The files have the PR prefix.
