business manager of DUCAT said.
“We got interested in Dr.Web AV-Desk as an excellent tool to secure
our networks and computers of our subscribers who only need to sign up
for the service and get reliable anti-virus protection. Our company
always tried to maintain the highest quality of provided services and
maximum security of its network. Our cooperation with Doctor Web is
another step in this direction”, Aleksander, Shvetsov, the technical
director of DUCAT noted.
“The number of Internet users worldwide is growing. So does the number
of viral threats. A top-quality security solution is required to
minimize security risks. Such a solution should also be available to
corporate customers as well as ordinary people. Dr.Web AV-Desk allows
provider companies to deliver the anti-virus as a service making it
much easier to obtain and to use”, Boris Sharov, the director-general
of Doctor Web commented upon the introduction of the anti-virus
service by DUCAT.

Doctor Web — the Russian developer of IT security software branded
Dr.Web — releases Dr.Web for Windows 5.0.
“Change of a version number always marks another milestone in
development of Dr.Web software. Growing complexity of contemporary
threats relevant for virtually any user drove us to focus on
cutting-edge protection features that would deflect attacks of known
viruses and secure users from unknown malware. Some features of the
new Dr.Web have no look-likes in any other anti-virus available
nowadays”, the author of Dr.Web anti-virus and technical director of
Doctor Web Igor Danilov commented upon the release.
New features and improvements
Cures what others fail to detect
Successful curing of active infections, exceptional resistance to
viruses, unique technologies for scan of processes in RAM and
unsurpassed capabilities for neutralization of active infections that
allow installing Dr.Web on an infected machine remain key
technological advantages of Dr.Web software. It also disarms complex
viruses like MaosBoot, Rustock.C, Sector. Technologies that enable
Dr.Web to counter active viruses rather than simply detect collected
malware samples have been further developed and honed for the new
version.
Immunity
Dr.Web for Windows 5.0 is very good at protecting itself and resisting
attacks of malware. Dr.Web SelfPROtect controls access and
modification of files, processes, windows and keys of the Windows
Registry related to the application. The self-protection module is
installed as a driver that can neither be stopped nor unloaded before
a system is rebooted.
Advanced detection
A number of entries in a virus database is not the only criterion that
determines efficiency of a present-day anti-virus. It should also be
able to recognize unknown threats and be ready to detect viruses that
are yet to come. The new feature of Dr.Web 5.0 called FLY-CODE is a
universal decompression technology that allows detecting viruses
disguised by means of packers unknown to Dr.Web. The anti-virus uses
special entries in its database and heuristic analyzer to suggest if a
packed file contains malicious code.
Origins Tracing™ is a unique non-signature detection technology that
has also been brought to a new level in Dr.Web 5.0. It has already
proven its efficiency during epidemics that caused data losses to a
large number of customers of other vendors. Origins Tracing™ enhances
traditional signature-based scan and the heuristic analyzer and
improves detection of unknown malware.
Anti-rootkit
Dr.Web for Windows is one of the few anti-viruses that can detect and
neutralize viruses that feature rootkit technologies. Users of other
anti-virus products put Dr.Web CureIt!® to a good use to cure their
machines of rootkits. The new version of Dr.Web features a brand-new
version of Dr.Web Shield™ to counter even next generation of rootkits.
Deep insight
Capabilities of an anti-virus engine to decompress archives and depth
of scan it can perform affect the quality of detection. Dr.Web can
check archived files at any nesting level. Even if a malicious program
has been compressed several times using various archiver programs,
Dr.Web shall detect it and disarm.
Higher performance
Dr.Web for Windows 5.0 has become even faster. Optimization and
introduction of new technologies gave a significant boost of speed to
the scanning process. Now the scanner checks RAM, boot sectors and
files on hard drives thirty percent faster.
New components
SpIDer Gate™
One of the key innovations implemented in Dr.Web 5.0 is a
full-fledged HTTP monitor called SpIDer Gate™. It scans incoming
and outgoing HTTP traffic and works with all known web-browsers.
It doesn’t affect system performance or slow down web-surfing.
Dr.Web parental control
Dr.Web parental control is another new feature implemented in
version 5.0. It will protect your children against unwanted
web-resources and shield them from contacts with
cyber-criminals. It can also disable usage of removable data
storage devices, block access to network devices and files and
folders so your personal information won’t be deleted
occasionally or compromised by a third party. Dr.Web parental
control is very efficient and doesn’t interfere with routine
activities of a user.
The new components are available only in Dr.Web Security Space.
“The new version comes to the market as two products. The first one is
a classical Dr.Web anti-virus for Windows while the second one is
Dr.Web Security Space that provides a user with the package of
software aiming to secure a system against modern Internet threats. We
hope that work of our developers will come in handy for every user
concerned with security of thier information which we have been
protecting since 1992”, Boris Sharov, the director-general of Doctor
Web commented.

Mon, 15 Dec 2008 01:00:00 +0100 December 15, 2008
As the year comes to an end, Doctor Web sums up all events related to
malware and outlines trends in its development for 2009. The share of
malicious code of the total number of files scanned on user machines
doubled this year while the amount of spam messages spreading malware
dropped significantly due to the widely discussed closure of McColo.
At the same time phishing attacks became more frequent. E-mail,
removable data storage devices and web-sites have been used to spread
malicious code over the Internet.
The number of files with malicious code found by anti-viruses on user
machines increased steadily at the beginning of 2008 and by April it
more than quadrupled. The figure didn’t change till July when the
number halved reaching 0.01% of the total number of scanned files in
August. It has remained virtually unchanged till the end of the year
which means that one scanned file out of ten thousand is infected. The
diagram below illustrates dependency between the share of infected
files and the total number of scanned files.
The subsequent diagram shows how a number of messages containing
malicious code changed through the year with their average share
amounting to 0,2-0,25 % of the total number of e-mails (meaning that
one message in five hundred had malicious code attached or embedded as
a script). Following the closure of the company hosting spammers it
has reduced to 0.02% (one message in five thousand contains malicious
code).
Most notorious species
BackDoor.MaosBoot, Win32.Ntldrbot (Rustock.C) and numerous
modifications of Trojan.Encoder have become the most remarkable
malicious programs of this year.
BackDoor.MaosBoot places its code in the boot sector and hides its
presence in the system using rootkit technologies. Several
modifications of this virus have been found since March.
Win32.Ntldrbot turned out to be the hide master with its numerous
techniques to conceal its presence that allowed it to elude virus
analysts for several months. The rootkit was so good at hiding that
many anti-virus vendors considered it to be no more than a myth.
Win32.Ntldrbot features powerful polymorphic protector implemented as
a kernel-level driver and special self-protection and anti-debugging
mechanisms. The rootkit also has features of a file virus, it filters
all calls to an infected file, injects its code into system processes
and starts sending out spam.
Developers of Doctor Web updated anti-virus software in timely manger
to ensure its efficient operation against BackDoor.MaosBoot and
Win32.Ntldrbot. Eventually Dr.Web turned out to be the first
anti-virus capable to counteract the malicious programs without
resorting to utilities from a third-party developer.
Trojan.Encoder has also become famous in 2008. The Trojan encrypts
documents in a compromised system and offers a victim to purchase a
decryption utility. Doctor Web registered several modifications of
this malicious program that differed in length of encryption keys and
in their visual manifestation in the system. Dr.Web analysts developed
a free decryption utility that can be obtained from the web-site of
Doctor Web.
Malicious e-mails
Messages spreading Trojan.DownLoad.4419 and Trojan.PWS.GoldSpy were
the most typically cases of distribution of malicious code via e-mail
in 2008.
Trojan.DownLoad.4419 got into a system as a “codec” required to view a
supposed pornographic video. Authors of the malicious program often
modified its executable and changed packers used to compress the file
every now and then. It made detection of the Trojan more difficult for
anti-viruses. As usual prompt updating of the Dr.Web virus database by
analysts allowed Dr.Web software to detect numerous variations of
Trojan.DownLoad.4419.
A wide variety of techniques was applied to spread Trojan.PWS.GoldSpy
that came as a an e-card or as an attachment to a threatening message.
In particular such messages warned a user that he would be
disconnected from the Internet due to his violation of a copyright. In
latest months Trojan.PWS.GoldSpy increased the number of e-mailed
Trojans that featured password stealing. The diagram below represents
how share of Trojan.PWS of the total amount of malicious e-mail
changed in 2008.
Social networks
Increased popularity of social networks among users in Russia also
attracted attention of virus makers who used fake accounts on social
networking web-sites to trick users into downloading malicious code.
Now owners of social networking web-resources employ various
techniques to secure their customers. Sometimes links sent with
messages are displayed as plain text so a user has to copy a link to
the address bar of a browser. Another option is displaying a warning
to a user who clicks on a link leading to an external web-page. By now
such measures have not allowed to solve the problem. Doctor Web offers
all registered visitors of social networking web-sites to use
high-quality anti-virus software or the free link-checker plugin from
Doctor Web to scan linked content for viruses.
ICQ as another tool spreading malware
ICQ instant messaging service was also used to distribute malicious
code this year. Malefactors created new accounts or used trusted UINs
of ordinary users whose machines were compromised by malware capable
of using the ICQ contact list to send messages.
Removable disks
As removable disks became the most common means to move information
from one computer to another they were also put to use by virus makers
as carriers of malicious code that entered Dr.Web database as
Win32.HLLW.Autoruner. Authors of the malware exploited the autorun
mechanism of Windows for execution of its code.
Removable data storage devices circulated widely among employees of
large companies and so did the infection. Companies and governmental
establishments were forced to restrict or even ban usage of removable
disks.
The next diagram shows how Win32.HLLW.Autoruner Trojans were rated
among most common viruses through 2008. It suggests that virus makers
tend to shift their preferences towards removable disks as means to
spread malware. They employ various techniques making it harder to
detect, analyze or remove a piece of malicious code from a flash
drive.
Win32.Sector
The file virus got an entire subsection of the review to itself as one
of the biggest troublemakers of 2008. It infected executables,
injected its code into system processes, disabled UAC in Windows Vista
and downloaded other malicious programs from the Internet. See how
Win32.Sector was detected by Dr.Web scanner in 2008 on the graph
below.
The last months of the year have been marked by the increased number
of phishing attacks. A user received a message that looked like an
e-mail from a legitimate financial institution and was offered to
follow a link to a bogus web-site that also looked like a genuine
web-site of a corresponding company. As a user got to such a site, he
was lured into submitting personal information including his credit
card number and PIN code or login and password used to access a paid
service via the Internet. Such messages were received by customers of
such respected banks and service providers as JPMorgan Chase Bank, RBC
Royal Bank, Google AdWords, PayPal and eBay.
In 2009 Instant massagers, removable disks and other alternative
channels for distribution of malware will become even more popular
among virus makers.
Authors of viruses will be perfecting their techniques that will
provide them with even more complex polymorphic packers and other
means to make analysis even more difficult. Numerous vulnerabilities
found in operating systems and other software will be exploited by
malefactors just as well. Doctor Web also expects that a number of
e-mails containing malicious code will be rising at the beginning of
2009.
Detection and curing features of anti-viruses are also improved.
That’s why some cyber criminals have to change their activities. For
example, distributors of Trojan.DownLoad.4419 start sending e-mails
providing links to advertising web-resources instead of malware.

Doctor Web reports on discovery of a new Trojan — Trojan.Locker.8 —
that emerged on the Internet on December 9, 2008. This malicious
program blocks access to files and folders on a hard drive and offers
a victim to contact authors of the malware for instructions to regain
access to their information
The two megabyte Trojan file packed by ASPack is rather large for
malware When the Trojan is launched, a key generator Window appears on
the screen. While the window has nothing to do with actual activities
of the malicious program, it shows that Trojan.Locker.8 can be
disguised as a key generator designed by crackers to activate software
products by Adobe Systems.
Key generator for Adobe Systems products Once launched Trojan.Locker.8
renames files and folders on all disk partitions except the system
partitions. New file names violate Windows file naming standards so
files become inaccessible even though their content is unchanged.
After that the program creates its copy (answer.exe) on the desktop
and on all partitions containing inaccessible files. Running the file
shows a warning message that informs a user that his data has been
locked and offers to contact offers of the Trojan to unlock using
contact information provided in the message.
Files on the system drive also become inaccessible including files
placed in my documents and on the desktop even though the virus makers
claim that no changes are done to the system drive..
Doctor Web offers a free utility to unlock access to files in a system
compromised by the Trojan. It can be downloaded from the official
web-site of the company. Doctor Web strongly advises against
contacting the virus makers.

Subscribers of the TRINITY network receive free anti-virus protection
following another successful deployment of DrWeb AV-Desk in the
Krasnoyarsk region.
PUBLICITY company that owns and administers the TRINITY network
decided on adopting Dr.Web AV-Desk in autumn 2008. The anti-virus as a
service arose interest of subscribers during the testing period. Even
then Dr.Web AV-Desk reduced the number of support calls that were
often caused by activities of malware.
“Maximum comfort of subscribers is the corner stone of our network
administration policy that drove us to search for a simple way to
secure our customers from possible virus attacks. Some users lack
experience or skill to configure software installed on their machines
properly, let alone protection against malware spreading on removable
devices, via e-mail and HTTP traffic. The only solution capable of
protecting a large network available on the market at that moment was
Dr.Web AV-Desk. It fulfilled our requirements as an easy-to-use and
reliable anti-virus tool providing centralized real-time virus
monitoring and friendly user interface", Andrei Aleksandrov, the head
of PUBLICITY said.

Doctor Web — the Russian developer of IT security solutions branded
Dr.Web —reports upon the introduction of the Dr.Web anti-virus service
by the CSN Internet service provider that has become the third company
protecting its subscribers by means of Dr.Web software in the Belgorod
region.
One of the largest provider companies in the region has started
delivering the anti-virus service to its subscribers at the end of
November following a successful deployment of Dr.Web AV-Desk. The
innovative Internet-service has already been put to good use by more
than fifty access providers in Russia and the CIS offering their
customers efficient protection against malware and spam along with
broadband Internet.
Prior to the deployment numerous home and small business customers
were constantly faced with the threat of infection that would spread
all over the network from a single compromised host. “Dr.Web AV-Desk
fully complies with our requirements to anti-virus software. It is
very easy to install and the price is quite reasonable. Add low use of
traffic and subscription management tool and you get as many benefits
as no other anti-virus software can provide”, Vladimir Ilyin, the
manager of information systems department at CSN commented on
cooperation of the ISP with Doctor Web.
The test deployment of Dr.Web AV-Desk lowered the number of network
failures caused by malware and reduced spam traffic. A number of calls
for support also went down “Hopefully the deployment will raise the
security of our subscribers to the level that would make their work in
the Internet safe and comfortable and consequently strengthen our
position on the local provider market”, Aleksy Prokopenko, the head of
CSN said.
About CSN
CSN is an ISP operating in the Belgorod region with it wireless and
optical fiber networks found virtually in every town. The company also
plans, builds and administers computer systems and networks,
distributes computer hardware and maintains office automatic telephone

The closure of McColo Corporation responsible for 75 per cent of world
wide spam traffic divided the reported month into two equal parts.
Even though e-mail remains the most common means to spread malware
virus makers also find other ways to bring malicious code to user
machines
AutoIt-worms
A freeware automation language for Windows called AutoIt is very easy
to learn and provides wide opportunities for virus makers. The last
month showed their growing interest in this scripting language. Even
though an AutoIt program is written as a script, such a script can be
compiled into a packed executable with its shrouded code being very
hard to analyze. November saw an AutoIt worm spreading via removable
data storage devices instead of e-mail.
Viruses spreading on removable devices are especially dangerous for
companies and governmental institutions forced to introduce special
measures to contain the infection. Companies adopt software that
allows them to restrict usage of removable devices and sometimes
impose a temporary ban on use of removable drives.
Dr.Web anti-virus 5.0 currently undergoing open beta-testing allows to
unpack files of an AutoIt worm and to analyze its scripts. Viruses
written in this script language enter the Dr.Web database as
Win32.HLLW.Autoruner.
Mail viruses
Prior to the closure of McColo spam mailings distributing malware came
in high numbers. Below we will take a closer look at diverse methods
used to lure a user to launch a malicious file.
Trojan.PWS.GoldSpy.2454 was disguised as an e-card. Even though fake
cards have long been known to Internet community they still remain
efficient. The name of a malicious file is card.exe. Messages with a
link to a malicious file were used to spread another modification of
the malware – Trojan.PWS.GoldSpy.2466.
[IMAGE]
Trojan.DownLoad.3735 was spread as a file with a double extension –
the attached active_key.zip contained the active_keys.zip.exe file.
The message informed a user that his account was suspended upon a
corresponding request supposedly sent by the victim. A user was also
offered to activate the account. However, the message didn’t provide
any reference to a service related to the blocked account. No wonder
that details of the activation were said to be found in the attached
document which turned out to be an executable file containing
malicious code. Other messages spreading the same Trojan informed a
user upon changes in certain clauses of an agreement.
[IMAGE]
Messages with attached Trojan.PWS.GoldSpy.2456 threatened a user with
a forced disconnection from the Internet caused by a violation of the
copyright. Activates of a victim related to the alleged violation for
the last six months were said to be listed in an attached file
(user-EA49945X-activities.exe) which was nothing more than another
malicious program. The U.S presidential election was also used as a
message topic in e-mails spreading the Trojan.
[IMAGE]
Another mailing notified a user upon a failed delivery of a package
caused by an incorrect recipient address. An attached invoice was
detected by Dr.Web as Trojan.PWS.Panda.31
[IMAGE]
.Our analysts also registered several mailings advertising easy money
on eBay. An html-file attached to a message was detected by Dr.Web as
Trojan.Click.21795. The file contained an encrypted script that
directed a user to a web-site advertising training courses. Another
similar mailing advertised a new way of advertising using RSS and free
promotion of web-sites using services by Google and Yahoo
The closure of McColo Corporation reduced spam traffic significantly
but was only a short outage. Now mailings related to malware have been
short-term though the spam traffic sometimes has been rather high.
Such mailings included Trojan.PWS.Panda.31 spam e-mails and messages
containing an encrypted script detected by Dr.Web as
Trojan.Click.21795.
Authors of Trojan.DownLoad.4419 applied a new technique offering a
link to download a beta version of Internet Explorer 8 from a bogus
web-site.
[IMAGE]
A mailing in German described in the previous review from Doctor Web
also reemerged. It prompted a user to view important financial
information provided in an attached file. Earlier a shortcut and a
piece of malicious code had been placed on one folder contained in the
attachment while in November they were separated with the link placed
outside the folder. Dr.Web detects this Trojan program as
Trojan.DownLoad.16843.
[IMAGE]
Phishing
November 2008 also saw a wave of phishing targeting users of online
payment systems, Internet banking and other paid services in several
countries. In particular customers of JPMorgan Chase Bank, RBC Royal
Bank and usrs of AdWards and PayPal became victims of the phishing
attack.
[IMAGE]
[IMAGE]
Specialists of the virus monitoring service of Doctor Web added 25 461
entries to the virus database in November with average 850 new entries
per each day. Mind that one entry in the Dr.Web database allows the
software to detect numerous modifications of one virus. The figures
show that regular updating of anti-virus software as often as once per
hour becomes a necessity. Dr.Web automatic updating provides such an
updating frequency quite easily. In addition a good anti-spam module
becomes indispensable for normal work protecting against irrelevant
and harmful e-mail messages.

Doctor Web reports a significant increase of new viruses spreading on
removable data storage devices. Malicious programs created using the
AutoIt scripting language with their shrouded code are very hard to
analyze.
Automatic launch of the malicious code placed on a removable device
has become one of the main causes of infection in recent months. The
malicious code is classified by Dr.Web as Win32.HLLW.Autoruner.
The number of the new viruses grows along with the popularity of
AutoIt (a freeware automation language for Windows). The language is
very easy to learn and provides wide opportunities for virus makers.
The script code of such a virus can also include other malicious
binary files with all of them compressed using various packers. When
other malware is included in an AutoIt script it makes them very hard
to detect by anti-virus software.
Viruses infesting systems from removable devices has become an urgent
issue with many companies and governmental institutions restricting
usage of removable data storage devices by employees. So the US army
suspended use of USB disks and flash drives aiming to contain spread
of a worm in its networks. Many companies also adopt special software
that restricts usage of removable devices.
“Various executable packers and obfuscated code are typical techniques
employed by virus makers. Now they use features of the AutoIt
scripting language to which we provide a prompt response. For example
the beta-version of the Dr.Web anti-virus 5.0 currently in public
testing features recompilation of AutoI tmalware that allows analyzing
malicious scripts and unpacking executables included in AutoIt worms”,
Vladimir Martyanov, the virus analyst of Doctor Web remarked.
Doctor Web recommends all Windows users to disable the autorun of
removable data storage devices (USB Flash Drive, CD/DVD, removable
hard drives) and reduce the risk of infection. Besides, files placed
on a device should be checked using an anti-virus with the latest
virus definitions before you launch or open any of the files.

Doctor Web warns Internet-users of a mail-virus epidemic started on
November 25. Though the recent closure of web host McColo Corporation
reduced spam levels as much as by 70 percent malefactors are
persistent in their search for new ways to spread malware with spam.
By now one of such mailings has been amounting to 50 percent of
infected mail traffic.
Starting November 25 users started receiving messages in German with
the attached abrechnung.zip file (translated into English as
“statement of account”). Message text can be different but the aim is
to lure a user to open an attached file. The attached archive contains
abrechnung.lnk and the scann folder with the scann.a file. This
executable file is detected by Dr.Web anti-viruses as
Trojan.DownLoad.16843. The file structure of the archive shows that
probably a user is meant to launch the abrechnung.lnk file (by default
its extension is hidden in Windows Explorer) instead of opening the
folder. Eventually the scann.a file will be launched.
This executable injects malicious code into svchost.exe and
explorer.exe processes and downloads other components of malware from
servers located in China. This Trojan can also spread as the
system.exe file on removable disks.
.According to the virus laboratory of Doctor Web spam messages
spreading Trojan.DownLoad.16843 amount to 50 percent of infected mail
traffic.
Messages with links to pages containingTrojan.DownLoad.4419 are also
back. The latest mailing related to the Trojan started Monday evening.
This time a user was offered to download a beta version of Microsoft
Internet Explorer 8 instead of an adult video.
Doctor Web recommends solutions from its Dr.Web Security Suite to
ensure anti-virus and antis-am protection. As usual users should also
be careful when decide to follow instructions provided by a suspicious
message about free services or fiscal claims.

On November 22 2007 Doctor Web launched the Dr.Web AV-Desk innovative
service as a part of its development strategy following latest trands
of the anti-virus software market. The first deployment took place at
one of the largest ISPs in Moscow. Currently Dr.Web anti-virus as an
online service is used by hundreds of thousands of registered
subscribes of over fifty providers in Russia, Ukraine, Kazakhstan,
Kirgizstan, Estonia, Bulgaria and China.
In one year Dr.Web anti-virus has reached farthest regions of Russia
where one will have a hard time searching for a boxed software
product. Dr.Web AV-Desk brought reliable anti-virus protection to
every computer connected to the Internet. Distribution channels of
provider companies made the anti-virus available to people from
various social groups and allowed the companies to profit from the
security of their networks. And it turns out that Dr.Web AV-Desk has
come in the right place and in the right time.
Numerous benefits brought by the Internet service have been fully
appreciated by service providers Activities of malware have negative
impact on the quality fo access services and on the reputation of a
provider. Here Dr.Web AV-Desk steps in as a very efficient tool
enforcing loyalty of customers who are not just willing to have
services but to have them safely.
One of the keys to the success of the anti-virus service is its easy
subscription procedure. Following the Security as a Service principle
it comes as another online service. A user obtains an installer
download link with one mouse-click in his personal area at the website
of a provider company.
A complete list of companies offering the anti-virus service can be
found at the web-page of “The Web!” project that was announced by
Doctor Web in August 2008. The easy-to-use search system allows a user
to find companies delivering the Dr.Web anti-virus in his region. The
stats section can provide useful information to mass media writing
about IT and telecommunication. The statistical data updated every
twenty-four hours is collected automatically from several Dr.Web
AV-Desk servers
It’s not only ISPs that are interested in the Dr.Web anti-virus
service. It also protects users of a social network and is being
tested in several online banking systems. Dr.Web AV-Desk has already
been deployed successfully at Yandex.Money offering protection against
stealers of password and other personal information to more than one
million of its customers.
Time goes by and potential of the software appears to be unlimited.
The next year will see another Internet service from Doctor Web –
Dr.Web Mail Desk.

Doctor Web — the Russian developer of IT security solutions branded
Dr.Web — has updated Dr.Web LiveCD used to restore a system rendered
unbootable after a virus attack.
Now Dr.Web LiveCD can also be loaded from a flash-drive using the
CreateLiveUSB script. A user can specify a partition of a flash drive
on which he wants to place Dr.Web LiveCD. If no partition is
specified, CreateLiveUSB will enter a stand-by mode. After that a user
needs to insert a flash drive into a USB-port. The script won’t change
or remove any data stored on a device. However, it is recommended to
backup the files on another drive before you use it to load Dr.Web
LiveCD.
Besides, the updated version features support of Intel graphic chips
(i810 drivers) and has issues with Matrox video cards and an X.Org
video drive for Intel fixed. Some changes have also been done to rule
out any boot errors.
что Dr.Web LiveCD is available for free. The updated version can be
obtained at http://www.freedrweb.com.

Doctor Web – the Russian developer of IT security solutions branded
Dr.Web – announces a successful deployment of Dr.Web AV-Desk in the
network of the Globalnie Telesystemi company that provides the
Internet to citizens of the Yaroslavl region. The company has joined
“Nauka-svyaz” and “Zavolga.Net” that already deliver anti-virus and
anti-spam protection as a service in the region.
A successful internal testing of the Dr.Web AV-Desk Internet-service
is followed by its commercial launch. Starting in November 2008
Globalnie Telesystemi offers its customers to sign up for the Dr.Web
anti-virus service and receive reliable protection against viruses and
other malware and use the service free of charge till December 31.
“While surfing the web our customers being unaware of a danger often
fell victims to viruses. As we detected a dramatic increase of traffic
for an infected host, our specialists had to disconnect it to cure an
infected system. Of course it took time and extra resources. That’s
why we started searching for a solution that would protect computers
of our subscribers and wouldn’t be too costly. Now the Internet
service from Doctor Web allows any of our customers to use the Dr.Web
anti-virus service. And it is much more convenient than buying a boxed
anti-virus”, Mikhail Zilberman, the head of Globalnie Telesystemi
said.

Doctor Web — the Russian developer of IT security solutions branded
Dr.Web – unveils the beta-version of Dr.Web for Windows 5.0. Now the
anti-virus engine works up to 30% faster compared with Dr.Web 4.44,
recognizes even greater number of packers and archivers, has malware
detection even more improved. The new version is also enhanced with a
parential control module and HTTP traffic scanner - SpIDer Gate. All
features of the software are configured now using the SpIDer Agent
control centre.
The new anti-virus engine created using cutting-edge Dr.Web
technologies for detection of malware gives the anti-virus up to
thirty percent gain of speed while retaining traditionally low system
requirements and utmost efficiency. Dr.Web for Windows 5.0 beta is
equally good at resisting virus attacks and in most cases can be
installed in an infected system and cure it. The new Dr.web protects
itself against malware aiming to disable an anti-virus. The
self-protection driver restricts access to a network, files and
folders and to certain registry branches ensuring that no component of
Dr.Web for Windows 5.0 is disabled by a malicious program.
Following its predecessors Dr.Web for Windows 5.0 beta can scan
archives of any nesting level and recognizes even greater number of
packers.
Dr.Web for Windows 5.0 features several types of filtering for
Internet traffic. SpIDer Gate scans incoming and outgoing HTTP-traffic
real-time intercepting all connections and performing data-filtering
so a user receives scanned web-content cleaned of malicious code.
Besides, users are offered the Parental control module to restrict
access to specified web-sites adding them to a list or using an
updated database of unwanted web-resources. It may also restrict usage
of a CD-DVD-ROM, a flash drives and other devices.
SpIDer Agent with its launch icon integrated with the interface of
Windows allows configuring all anti-virus components using a single
control panel.
Everybody is welcome to join the public beta-testing of the new Dr.Web
anti-virus. Register to access the beta-testing section of our
web-site. The beta-version is discussed on Dr.Web forum.

Doctor Web issues a warning as the new wave of phishing is coming up.
Last days have seen spam mailings exploiting names of large
international banks and Internet services including JPMorgan Chase
Bank, RBC Royal Bank and Google AdWords. Users received fraudulent
e-mails luring them into submitting their personal information,
passwords or bank account data on fake web-sites.
Present day phishers employ more and more devious technique, so prompt
alerting becomes a high priority task. In the face of the global
financial crisis online swindlers rush to snare clients of large
international banks. Last week saw a lot of message copying corporate
design of the banks and tricking users into entering their personal
information on specifically designed fraudulent web-sites.
Customers of JPMorgan Chase Bank were among targets of the phishing
attacks. They were recommended to verify their online account access
information using a specified link. A false web-site within the BIZ
Internet domain had nothing to do with JPMorgan Chase Bank and data
provided by a victim on the web-resource was obtained by a phisher.
Another mailing for customers of JPMorgan Chase Bank offered adding
USD 50 to an account of a recipient for answering five questions. A
web-form on a fraudulent web-site provided five simple questions and
extra fields for a PIN code and a credit card number of a victim.
Clients of RBC Royal Bank received similar messages informing that a
user account would be disabled after three failed attempts to sign in.
Clicking on a provided link brought a user to a page that looked like
a legitimate main page of the bank web-site in the EDU domain. A
victim had to enter a credit card number and a password.
A number of e-mails aiming to obtain access data of customers of
Google AdWords also increased. A phishing e-mal notified a user that
display of his advertisement had been suspended while his account was
still valid. A user was offered to use his login and password to
update his “billing data”.
Doctor Web urges users to be more attentive while viewing message from
banks and other financial institutions. Read a message carefully and
consult the specified company for more information before you decide
to reply. Also, pay attention to the top level domain name present in
a link you are offered to follow.
