U S E R G U I D E The settings of Mail Anti-Virus are available from The Bat! if this option is selected in the protection scope settings of Mail Anti-Virus. To configure email scanning in The Bat! you must define the following criteria: which mail stream (incoming, outgoing) should be scanned; when mail objects should be scanned (when opening a message, before saving to disk); what actions are to be performed by the mail client if dangerous objects are detected in email messages. For example, you can select: Attempt to disinfect infected parts – if this option is selected, the attempt is made to disinfect the infected object; if it cannot be disinfected, the object remains in the message. Delete infected parts – if this option is selected, the dangerous object in the message is deleted regardless of whether it is infected or suspected to be infected. By default, The Bat! places all infected email objects in Quarantine without attempting to disinfect them. Email messages that contain dangerous objects are not marked with the special subject add-on when scanned by the plug-in for The Bat!. To switch to the email scan settings in The Bat!: 1. Open the main window of the The Bat!. 2. In the Properties menu, select Settings. 3. Select the Virus protection object from the settings tree. WEB ANTI-VIRUS Each time you work on the Internet, you endanger information stored on your computer, by exposing it to a risk of being infected with viruses and other malware. They may penetrate your computer when you download free applications or view information on websites that had been attacked by hackers before you have visited them. Moreover, network worms may penetrate into your computer even before you open a web page or download a file, just at the moment your computer establishes an Internet connection. Web Anti-Virus protects information received by your computer and sent from it over HTTP, HTTPS and FTP protocols, and prevents hazardous scripts from being run on your computer. Web Anti-Virus only monitors web traffic transferred via ports specified on the list of monitored ports. A list of monitored ports that are most commonly used for data transfer, is included in the Kaspersky Internet Security distribution kit. If you use ports that are not included in the list of monitored ports, you should add them to the list of monitored ports (see section "Creating a list of monitored ports" on page 119) to ensure protection of web traffic transferred via them. Web Anti-Virus scans web traffic with regard for a specific collection of settings named security level. If Web Anti-Virus detects a threat, it will perform the prescribed action. Malicious objects are detected using both Kaspersky Internet Security databases and a heuristic algorithm. Kaspersky Lab advises you not to configure Web Anti-Virus settings on your own. In most cases, it is sufficient to select an appropriate security level. 88
A D V A N C E D A P P L I C A T I O N S E T T I N G S Web traffic scan algorithm Each web page or file that is accessed by the user or an application via the HTTP, HTTPS, or FTP protocols is intercepted and scanned for malicious code by Web Anti-Virus: If a web page or a file accessed by the user contains malicious code, access to it is blocked. A notification is displayed that the requested file or web page is infected. If the file or web page does not contain malicious code, the program immediately grants the user access to it. Script scan algorithm Each script run is intercepted by Web Anti-Virus and is analyzed for malicious code: If a script contains malicious code, Web Anti-Virus blocks it and displays a notification on the screen. If no malicious code is discovered in the script, it is run. Web Anti-Virus intercepts only scripts based on the Microsoft Windows Script Host functionality.

In the left part of the window, in the Protection Center section, select the Web Anti-Virus component. 3. In the right part of the window, uncheck the Enable Web Anti-Virus box. 89
