Press Release Summary: Doctor Web, Ltd., a Russian developer of IT-security
solutions under the brand-name of Dr.Web, announces the release of a new version of
Dr.Web Anti-virus for Windows - 4.44.

Press Release Body: Technologies
. Dr.Web ShieldT - counteraction to rootkits
The so-called rootkits which actively protect themselves from detection by the
anti-virus programs become the main trend in the development of viral codes. An
anti-virus program without anti-rootkit technology makes the program a useless and
defenseless computer toy, very often a very expensive one. Developers of new Dr.Web
version have designed a special component for Dr.Web GUI scanner to counteract
rootkits - Dr.Web ShieldT. Designed as the driver, it secures access to virus
objects hiding in the operating system.
. Origins TracingT - non-signature search of unknown viruses

Dr.Web developers have invented a unique algorithm of non-signature detection of
malicious objects which supplements traditional signature-based search and Dr.Web
heuristic analyzer, making the detection even more efficient. The names of
ill-intended objects detected with the help of this new technology have the
".Origin" extension.
The new technology significantly improves the quality of detection of unknown
viruses. \"Our analyzers and developers have achieved a substantially new level of
anti-virus technology, - comments Boris Sharov, CEO of Doctor Web, Ltd. We have long
explored the possibility to implement our new detection methods to be able to detect
unknown viruses to assure the highest protection level for our customers. Hopefully,
it will be a good present for them".

Dr.Web Anti-virus - CURES computers from viruses
The quality of the program's operation and not just its presence in the computer has
always been the characteristic feature of Dr.Web Anti-virus. Not only the ability of
the anti-virus to detect viruses, but also to cure from viruses is extremely
important for modern av-programs, the ability not only to delete the infected files
from computers, but also to restore them. Dr.Web is one of a few anti-virus programs
that cures efficiently from viruses. A comparative review held by
www.anti-malware.ru in September, this year clearly shows unachieved for competitors
leadership of Dr.Web 4.44 beta(!)-version of all 15 participants in the curing
quality testing.

Support of Windows Vista
We understand that all our users have been waiting for Dr.Web for Windows Vista
compatibility news. Microsoft Corporation has introduced many security features in
Windows Vista that are supposed to block malicious programs and to enhance the
overall security of the system, but, much to our regret, these measures made it
extremely difficult for third party IT-security developers (of anti-virus programs
in particular) to efficiently work in the system and to protect it. Real security
means no compromise, and Doctor Web, Ltd. took a difficult for a company decision -
not to release the product until a real, and not declarative compatibility with
Windows Vista is provided. Dr.Web for Windows version 4.44 now supports MS Windows
Vista.

Efficient scanning speed
The scanning speed of the anti-virus is often the main reason for a user to choose
one or another anti-virus program. But high scanning speed can be achieved by
different ways. Sometimes, to increase the speed of the scanner av-vendors exclude
from the scanning such important object as archives, mail bases, etc. Some often
disable the heuristic analyzer, which also decreases the detection level of unknown
threats. In the result, higher than with the competitor programs scanning speed is
achieved on the account of the decrease of the protection level, but users impressed
with the blazing speed of the anti-virus are seldom told about it. Sometimes, to
increase the scanning speed some av-developers add the option, which allows to
specify the areas of the drive which will be controlled by anti-virus monitor. It is
done to increase the processing speed in programs which consume too many computer
resources, when the hard drives are scanned and reduce resources consumption of
their monitors at the cost of the lower protection level.

Developers of Dr.Web believe, that the idea of \"selective\" protection is defective,
as users are offered to protect just part, instead of the whole system.

It is most important to combine high scanning speed with the efficient detection
level. And this task is fulfilled by Dr.Web developers in new version in which scan
speed is increased by 30%.

More options in Dr.Web GUI scanner
. Additional driver called Dr.Web Shield makes part of the scanner now. It improves
significantly detection rate and curing capabilities of Dr.Web, counteracts to
rootkits. The driver is downloaded automatically when the GUI scanner is launched.
. Three check modes are implemented for users' convenience: Express, Complete, and
Custom Scans. The scanning in the Express and Complete modes does not require from
users selection of objects for scanning, which makes the communication with the
scanner even easier.
. Dr.Web interface has always been intuitively simple and understandable. It was not
changing with every version, so regular customers got used to it and felt
comfortable when they saw the same program's look from years to years. Now Dr.Web
Anti-virus has a slightly new face. The interface is modernized, but it is still
recognizable. The main scanner window, as well as the panes, now look a bit
different.

Updated anti-spam
In addition to anti-spam integrated into SpIDerMail, the utility for creation of
spam filtering rules for Outlook Express is included into the distribution. Now,
Dr.Web automatically creates rules to place e-mail messages marked as spam by Dr.Web
Anti-spam to predefined folder of Outlook Express.

Improved SpIDer Guard
Many changes and improvements have been made to SpIDer Guard file monitor. Its
operation is considerably improved, and its stability during the numerous
simultaneous file operations is increased a lot.

Graphical User Interface (GUI) of SpIDer Guard has been amended.
SpIDer Guard's operational stability under the load and its interaction with
different software running in the background mode have been improved.
Parameters of the Smart mode have been changed. Now in the Smart mode the run
processes are checked and the files are passed to check when they are saved only.

In new version of the file monitor users will receive notification balloons when the
databases have not been updated for more than 7 days - in the system tray over the
SpIDer Guard icon. If the automatic updating utility is installed, an update will be
offered.

Updating utility
In new version the updates can be downloaded as archives. The upgrades of components
can now be downloaded also as patches. It is not necessary any more to download the
new version of the component to upgrade it. The upgrading can be done by patches
only. This saves on Internet traffic and Dr.Web's operation becomes even more
invisible for users.
