OVERVIEW
1.1. What is Kaspersky Anti-Spam
Personal
Kaspersky Anti-Spam Personal is designed to protect Microsoft Outlook and
Microsoft Outlook Express users from unsolicited e-mail messages (spam).
Firstly, such protection is implemented through checking various attributes of the
messages: sender's and recipient's address, message headers (including the
From and To headers).
Secondly, content filtering method is used that involves the analysis of the
message content (including the Subject header) and of the attached files

. This
includes the use of unique linguistic and heuristic algorithms based on fuzzy
comparison of the text fragments with sample messages and on more
comprehensive analysis of the text, formatting features and other attributes of the
messages. E-mail filtering technology used by Kaspersky Anti-Spam Personal
was developed by JSC Ashmanov & Partners (see Appendix D, page 56).
Attention! Every day new types of spam messages appear. In order to
ensure that you have an up-to-date product, it is necessary to update
the anti-spam database as frequently as possible. Make sure that you
update anti-spam database immediately after you have installed
