What is Web Anti-Virus

Whenever you use the Internet, the information stored on your computer becomes subject to the risk of infection from dangerous scripts located on websites.

InformationScript is a special program or script file which performs specific instructions according to "scenario". Scripts are used to provide normal page display. Malicious scripts are used to load a special program (exploit) which uses system vulnerabilities to access personal data.

The Web Anti-Virus component in Kaspersky Internet Security 2013 is designed to ensure security while using the Internet. It protects your computer against data coming in via the HTTP and HTTPS protocols. The component also scans FTP traffic. For example, if you browse a web page which contain a link to an infected FTP resource, then this resource will be blocked.

Each open website or file is intercepted by Web Anti-Virus and analyzed for malicious codes. Kaspersky Internet Security 2013 analyzes files using its anti-virus databases and the heuristic analysis technology. If a web page or an object you apply to is infected, then access to this web page or file will be blocked. If the web page or the object is not infected, you will be able to work with it.

The Web Anti-Virus component in Kaspersky Internet Security 2013 includes the following modules:

  • Safe Surf. The module includes the Kaspersky URL Advisor module and the Blocking Dangerous Websites module. The modules block opening of dangerous websites that provides safe Internet surfing.
  • Geo Filter . To help avoid websites from the most infected regional domains, the module can filter out any region of your choice.
  • Trusted URLs. You can create a list of trusted web addresses which will not be scanned by Web Anti-Virus.

Additionally, Kaspersky Internet Security 2013 includes a new technology proactive detection of phishing resources. When you access a web site, this web site is analyzed for typical of harmful actions. As a result, the resource is detected as a malicious one and will be blocked, even if the data about the resource is not included to the database.

How to change action on threat detection

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 Kaspersky Internet Security databases and the heuristic algorithm. The database contains 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 entered in the database. 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.

In order to change actions to be performed by Web Anti-Virus on detected threats, perform the following actions:

  1. Open the main application window.
  2. In the right upper corner of the main application window, click Settings.

  1. In the Settings window go to the Protection Center tab and select the Web Anti-Virus component.
  2. In the Action on threat detection section select the required action depending on the selected protection mode:
    • Select action automatically. Available if the automatic protection mode is enabled. If you select this variant, then the application will select actions on detected threats automatically.
    • Prompt for action. Available if the interactive protection mode is enabled. If you select this variant, then the application will prompt for action on each threat detection.
    • Block downloadWeb Anti-virus blocks an object and issues a pop-up message that informs the user that an object or a page is infected.
    • Allow downloadWeb Anti-Virus does not block an object or a page. After an object is downloaded it will be scanned by File Anti-Virus and Proactive Defense.
  3. Click on the OK button.
  1. Close the main application window.
