WEB TRAFFIC PROTECTION

Whenever you use the Internet, you subject information stored on your computer to the risk of infection by dangerous

programs. These can infiltrate your computer while you are downloading free software, or browsing knowingly safe sites,

which have recently suffered network attacks. Moreover, network worms can penetrate your computer before you open a

webpage or download a file just because your computer is connected to the Internet.

The Web Anti-Virus component is designed to ensure the security while using the Internet. It protects your computer

against data coming into your computer via the HTTP protocol, and also prevents dangerous scripts from being executed

on the computer.

Web protection monitors HTTP traffic that passes only through the ports included in the monitored port list. A list of ports

that are most commonly used for transmitting email and HTTP traffic is included in the Kaspersky Anti-Virus installation

package. If you use ports that are not on this list, you must add them to the list to protect traffic using these ports.

If you work in a non-secure area, you are recommended to use Web Anti-Virus while working in the Internet. If your

computer is running on a network protected by a firewall of HTTP traffic filters, Web Anti-Virus provides additional

security when using the Internet.

A collection of settings, called the security level, determines the way of scanning the traffic. If Web Anti-Virus detects a

threat, it will perform the assigned action.

Your web protection level is determined by a group of settings. The settings can be broken down into the following

groups:

protection scope settings;

settings that determine the efficiency of traffic protection (using heuristic analysis, scan optimization).

Kaspersky Lab advises you not to configure Web Anti-Virus component settings on your own. In the majority of cases,

selecting a different security level is sufficient.

To edit Web Anti-Virus settings:

1. Open the main application window and click the Settings link in the top part of the window.

2. In the window that will open, in the Protection section select the Web Anti-Virus component.

3. Click the Settings button for the component you have selected.

4. Make the required changes in the component settings.
