Threats to computer security 35
The application detects objects containing new malware programs based on their
behavior. The code of a new malware program may not fully or even partially
coincide with that of a known malware program, but it will contain characteristic
command sequences, such as opening a file, writing to a file, or intercepting
interrupt vectors. The application can determine, for example, whether a file is
infected with an unknown boot virus.
Objects detected using the proactive method are given the status potentially
dangerous.
INTERNET THREATS
Kaspersky Lab's application uses special technologies to prevent the following
computer security threats:
 Spam, or unsolicited incoming mail (see section "Unsolicited incoming
mail or Spam" on page 35);
 phishing (on page 36);
 hacker attacks (on page 36);
 banners display (on page 37).
SPAM OR UNSOLICITED INCOMING MAIL
Kaspersky Lab's application protects users from spam. Spam is unsolicited
incoming mail, often containing advertisements. It places an additional load on
the network and onn the e-mail provider's mail servers. The recipient pays for the
traffic created by spam, and legitimiate non-spam mail travels slower. As a result,
spam is illegal in many countries.
Kaspersky Internet Security integrates into e-mail clients )Microsoft Outlook,
Microsoft Outlook Express and The Bat!), and scans incoming messages.
Message which it detects as spam are prcessed according to user-specified
actions: for example, the messages could be moved to a special folder, or
deleted.
Kaspersky Internet Security detects spam with a great degree of accuracy. It
applies several spam filtering technologies, including: analysing the sender's
address, and words and phrases in the message’s subject line; it detects graphic
spam, and it uses a self-training algorithm to detect spam based on the message
text.
