In the window that opens, on the Performance tab in the Scan optimization section, check the Scan only new and changed files box. 82 ADVANCED APPLICATION SETTINGS MAIL ANTI-VIRUS Mail Anti-Virus scans incoming and outgoing messages for malicious objects. It starts when the operating system launches and runs continually, scanning all email messages sent or received via the POP3, SMTP, IMAP, MAPI and NNTP protocols, as well as over secure connections (SSL) via POP3 and IMAP (see section "Encrypted connections scan" on page 100). The indicator of the component's operation is the application icon in the taskbar notification area, which looks like whenever an email message is being scanned. Mail Anti-Virus intercepts and scans each email message received or sent by the user. If no threats are detected in an email message, it becomes available for the user. You can specify the types of messages which should be scanned and select the security level (see page 85) (configuration settings affecting the scan intensity). By default, the signature analysis ­ a mode that uses records from application databases to search for threats ­ is always enabled. Furthermore, you can enable filtering of attachments (see page 86), which allows automatic renaming or deletion of specified file types. If a threat is detected in a file, Kaspersky Anti-Virus assigns one of the following statuses to the file: Status designating the type of the malicious program detected (for example, virus, Trojan). Potentially infected (suspicious) status if the scan cannot determine whether the file is infected or not. The file may contain a code sequence typical of viruses and other malware, or the modified code of a known virus. After that, the application blocks the email message, displays a notification (see page 122) of the detected threat on the screen, and performs the action specified in the settings of Mail Anti-Virus. You can change the actions to be taken when a threat is detected (see section "Changing the action to take on infected email messages" on page 86). If you are working in automatic mode (see section "Selecting a protection mode" on page 63), when dangerous objects are detected, Kaspersky Anti-Virus automatically applies the actions recommended by Kaspersky Lab specialists. Delete if disinfection fails, for suspicious objects ­ Move to Quarantine. If dangerous objects are detected when working in interactive mode (see section "Selecting a protection mode" on page 63), the application displays a notification on the screen that you can use to select the required action the list of available ones. Before attempting to disinfect or delete an infected object, Kaspersky Anti-Virus creates a backup copy for subsequent restoration or disinfection.
