 Kaspersky Anti-Hacker 1.9.37 Final - Kaspersky Anti-Hacker is a 
personal firewall application, that will provide full-scale protection 
for PC, running Windows, from all the attempts of non-authorized access 
to data, as well as from the hacker attacks both from Internet and 
Intranet.
Kaspersk Anti-Hacker provides control over the computer activity on the base of two-level analysis of system network activity.
Tracking activity of 
Internet-connected applications (high -level operations). Integrated 
analysis of activity of such Internet- connected applications like 
Web-browsers, mail applications, file transfer application, etc.
Packet filtration of incoming 
and outgoing data (low-level operations). At this level Kaspersky 
Anti-Hacker analyses directly the packets, sent or received by computer.
Filtration rules setting
According to the user tasks software allows for creation or changing any set of rules for the tracking of applications activity as well as for packet filtration.
Ability to set up special 
security rules for the internet-connected applications can be 
represented in Internet access to be allowed or denied for the 
particular application depending on its type – mail client, 
internet-pager, web-browser, etc., or to allow specific type for 
activity for each concrete application (i.e. to set remote services and 
addresses with whose the application can interact).
On setting packet filtration 
rules, it’s possible to allow or to deny transferring data of specific 
types. The decision on the following actions with the packet is taken on
 the base of analysis of the information stored in the packet header: 
sender or recipient’s IP-address, data transfer protocol to be used, 
etc. This type of rules can be applied to all applications. Packet 
filtration also provides effective protection against hacker attacks.
Customized security levels
Depending on your tasks, 
Kaspersky Anti-Hacker allows for making choice among the five security 
levels starting with complete protection turn-off up to total block of 
all Internet connections, for each of whose levels you can specify 
security and packet filtration rules.
Efficient protection against known types of hacker attacks
Kaspersky Anti-Hacker partly 
functions in automatic mode. Attack Detector provides reliable defense 
against such known types of hacker attacks like port scanning, ping, 
etc.
On choosing some security levels
 you can also use additional security tool – Stealth mode. Thanks to 
SmartStealth technology it becomes more difficult to detect your 
computer from outside. In this mode any network activity is prohibited 
if not explicitly allowed by the user rules. This mode allows for 
successful prevention of hacker attacks including DoS (Denial of 
Service), while having no negative influence on the user performance.
Automatic self-learning system
Kaspersky Anti-Hacker contains 
an ability to expand the list of security roles for Internet-connected 
application with the self-learning function. If an event occurs which is
 not described by the predefined rules, you can add the method of its 
handling to the list. In this way you can create security profile, which
 will ideally meet your requirements.
Check for integrity of executable files
Kaspersky Anti-Hacker provides 
applications protection from the unauthorized attempts to substitute 
their original executable files. If this kind of substitution detected 
there is an option to Block any further network activity of this 
application, due to all other rules in this list will be disabled; or to
 continue to trust to this application without making any changes in its
 rules. Check for executable files integrity is performed on the on the 
base of CRC sums, first calculated on file appearance in the system, and
 further periodic checking of their value.
