Protection against network attacks Protection of your computer against network attacks is provided only if you did not disable it during the installation of the application. Kaspersky Anti-Virus Personal Pro 5. 0 allows to protect your computer against network hacking attacks from the local area network or from the internet. Hacking attacks are detected based on the records contained in the database of the attacks known at the moment. This database is updated and the updates are installed along with the update of the anti-virus database (details see Chapter 6 on page 45). By default, protection against network attacks is started at Kaspersky Anti-Virus startup, monitors all network connections and checks all data received from the network irrespective of the source: local network or internet. As an attempt to attack your computer occurs, this attack will be blocked. A corresponding notification will be displayed on the screen (see Figure 26) that will contain information about the type of attack, IP address of the attacking computer and the local port (if possible). Settings of the real-time protection against network attacks are configured in the Network tab of the Real-time protection settings dialog box (see Figure 27). When you enable or disable the real-time protection using the Kaspersky AntiVirus context menu available via the system tray, the real-time protection against network attacks will also be disabled (see section 6. 2. 2 on page 48). If you decide to disable only protection against network attacks while leaving other real-time protection functionality enabled, uncheck the Enable real-time protection against network attacks box (see Figure 34). In order to apply the changes you have made you will have to restart your computer. 86 Kaspersky Anti-Virus® Personal Pro Figure 33. Notification about a network attack Figure 34. Configuring real-time protection against network attacks You can define Kaspersky Anti-Virus operation settings in the real-time network protection mode. Configuring the application 87 · Stealth mode. This mode allows only those network activities that have been initiated by the user or by programs installed on the user's computer; all other actions (remote connection to your computer, etc. ) will not be allowed. This means that your computer becomes virtually "invisible" for other computers. Besides, the stealth mode allows to prevent any types of DoS (Denial of Service) attacks. At the same time, the stealth mode does not have any negative impact on your internet activities as Kaspersky Anti-Virus allows any network activities initiated by the user. Stealth mode does not protect your computer from the harmful actions of trojan programs!By default the stealth mode is disabled. In order to enable it, check the Use stealth mode checkbox. · Notifications about network attacks.
