Kaspersky Small Office Security 3.0 (PC)

By default, Web Anti-Virus is enabled and operates in the mode developed by Kaspersky Lab specialists.

To enable or disable Web Anti-Virus, do the following:

1. Open Kaspersky Small Office Security 3 for Personal Computer.
2. In the upper-right part of the window, click the Settings link.

3. In the upper part of the Settings window switch to the Protection tab and select the Web Anti-Virus component.
4. In the Web Anti-Virus Settings section select or deselect the Enable Web Anti-Virus check box.
5. Click Apply.

6. Close the application window.

Web Anti-Virus can work in several modes called security levels. Each security level is a particular Web Anti-Virus preset created by Kaspersky Lab specialists. There are three security levels available in Kaspersky Small Office Security for Personal Computer.

To change the security level, do the following:

1. Open Kaspersky Small Office Security 3 for Personal Computer.
2. In the upper-right part of the window, click the Settings link.

3. In the upper part of the Settings window switch to the Protection tab and select the Web Anti-Virus component.
4. In the Security level section select the preferred preset:
   • High. This security level is recommended if no other HTTP traffic security tools are being used (firewall, proxy server).
   • Recommended. This security level is optimal for most situations, because it provides high protection level at a moderate resource intensity. This is a default security level.
   • Low. Use this security level if you have additional HTTP traffic protection tools installed on your computer (firewall, proxy server etc.).

5. Click OK and close the application window.

Each web page or file that is accessed by the user, or by a program via the HTTP and FTP protocols, is intercepted and analyzed for malicious code by Web Anti-Virus. Malicious objects are detected using both databases and the heuristic algorithm. The databases contain descriptions of all the malicious programs known to date and methods for neutralizing them. The heuristic algorithm can detect new viruses that have not yet been added to the database. Once the application detects malicious code while analyzing an object, the action taken by the Web Anti-Virus component depends on the option you have selected.

If the program operates in an automatic mode, then the action that should be performed on threat detection will be selected automatically.

To change an action performed on threat detection, do the following:

1. Open Kaspersky Small Office Security 3 for Personal Computer.
2. In the upper-right part of the window, click the Settings link.

3. In the upper part of the Settings window switch to the Protection tab and select the Web Anti-Virus component.
4. In the Action on threat detection section select the necessary action depending on the selected protection mode:
   • Select action automatically (if the automatic protection mode is selected). In this mode Web Anti-Virus will take an action recommended by Kaspersky Lab specialists.
   • Prompt for action (if the interactive protection mode is selected). In this mode Web Anti-Virus will prompt for action (allow or block) once suspicious activity is detected. You will need to choose either variant.
   • Block download. Web Anti-Virus will block an object and issue a pop-up message that an object or a page has been infected.
   • Allow download. Web Anti-Virus does not block an object or a page. Once the object is downloaded, it will be scanned by File Anti-Virus.

5. Click OK and close the application window.
