Description of the Anti-Spam component

The Anti-Spam component in Kaspersky Internet Security 2012 filters all incoming mail for unwanted mail (spam) and sorts it according to the settings configured by the user.

The Anti-Spam component has two methods to fight undesirable correspondence. Using the first ("precise") method, Anti-Spam in Kaspersky Internet Security 2012 defines a mail as unwanted by distinct phrases, by undesirable senders (whose addresses are already added to the Anti-Spam database), and by malicious or phishing links. 
The second ("expert") method consists of an evaluation of the likelihood of spam presence based on an analysis of the mail text and its service information.
 
The Anti-Spam component is embedded in the following mail clients as an add-in module:
  • Microsoft Office Outlook versions 2003/2007/2010
  • Microsoft Outlook Express (Windows Mail)
  • The Bat!
  • Thunderbird (embedded in Mozilla Thunderbird version 3.0 and above)

Attention

The Anti-Spam plug-in in Kaspersky Internet Security (all versions) cannot be installed in the portable version of this mail client (Mozilla Thunderbird Portable Edition)!

Mail analysis technologies

Kaspersky Internet Security 2012 includes the following mail analysis technologies:  

  • Heuristic analysis of technical mail headings. This analyzer identifies errors in the technical headings that contain information about: 
    • mail servers the mail was sent through,
    • antivirus scan status,
    • the level of urgency applied to the message,
    • the application used to create the message;

and marks the message as spam

  • Heuristic analysis of the mail's body text and the text in attached documents. This analyzer looks for signs of spam in the text through methods like determination of the theme of the text (for example, touristic advert) and the use of known spam phrases (for example, buy Viagra). 
  • Analysis of graphics contained in the mail. With this method, graphics are analyzed and compared to spam patterns in the signature database; the image is also analyzed for the presence of text, the characteristics of which are analyzed for spam.
    If the signature of an image contained in a message is known as a spam pattern, the message is marked as Spam
  •  
  • "Cloud" technologies (Kaspersky Security Network). The use of this technology enables on-the-fly reaction to the appearance of new spam. In Kaspersky Internet Security 2012 statistics about the activity of Kaspersky Security Network are now available from the main application window. This makes it possible to see how effectively "cloud" technologies are working and how reliably your computer is being protected. 

Anti-Spam training

In previous versions of Kaspersky Internet Security it was necessary to train the Anti-Spam component with a minimum of 50 genuine messages and 50 samples of spam. With the Anti-Spam component included in Kaspersky Internet Security 2012 training is no longer necessary, as information for its operations is taken from Kaspersky Security Network, which already has a database of sample spam messages.
