CHANGING HTTP TRAFFIC SECURITY LEVEL
The security level is defined as a preset configuration of File Anti-Virus settings. Kaspersky Lab specialists distinguish
three security levels. The decision of which level to select should be made by the user based on the operational
conditions and the current situation. You will be offered to select one of the following options for security level:
High. This security level is recommended for sensitive environments when no other HTTP security tools are
being used.
Recommended. This security level is optimal for using in most situations.
Low. Use this security level if you have additional HTTP traffic protection tools installed on your computer.
If none of the preset levels meet your needs, you can configure the Web Anti-Virus's settings (see section "Web traffic
protection" on page 58) on your own. As a result, the security level's name will be changed to Custom. To restore the
default component's settings, select one of the preset security levels.
To change the preset security level for web traffic:
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. Set the required security level for the component you have selected.
CHANGING ACTIONS TO BE PERFORMED ON DETECTED
OBJECTS
Once analysis of an HTTP object shows that it contains malicious code, the response by the Web Anti-Virus component
depends on the action you have selected.
Web Anti-Virus always blocks actions by dangerous objects and issues pop-up messages that inform the user of the
action taken. The action on a dangerous script cannot be changed – the only available modification is disabling script
scan module (see section "Selecting the scan type" on page 61).
If you are working in automatic mode (see section "Step 2. Selecting protection mode" on page 28), Kaspersky Anti-Virus
will automatically apply the action recommended by Kaspersky Lab's specialists when dangerous objects are detected.
To change the specified action to be performed on detected objects:
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. Specify the required action for the component you have selected.
CREATING A PROTECTION SCOPE
Creating a protection scope means selecting the type of scan (see section "Selecting the scan type" on page 61) of
objects by Web Anti-Virus, and creating the list of trusted web addresses, which contain information not subject to scan
for dangerous objects by the component.
You can create a list of trusted web addresses whose content you unconditionally trust. Web Anti-Virus will not analyze
data from those addresses for dangerous objects. This option may be useful, for instance, when Web Anti-Virus
interferes with downloading a particular file.
