NetQin Mobile Internet Cloud SaaS Protects Mobile Users from Latest Security Threats

BEIJING, March 4, 2011 - Recently, new spyware that causes privacy leakage was found on Google's
Android Market. Named "DroidDream", the spyware was embedded in repackaged
legitimate applications and uploaded to the Android Market by the developers
"Myournet", "Kingmall2010" and "we20090202". Mobile devices will be infected
after download. Google has removed more than 50 infected applications from
Android Market and remote deleted the infected apps downloaded to the users'
devices to prevent further spreading of the malware.

The bombardment undoubtedly has something to do with the open nature of
Android Market. As Android Market is providing more than 200,000 applications
for users all around the world, it also allows almost anyone to upload apps
as long as they register. Given such a situation, Android seems to be a
double-edge sword that caters to the demands of the vast number of users as
well as attracts a bundle of virus authors.

Even though Google has taken a series of control measures in the wake of
the event, there seems to be a need for more to be done, warned NetQin Mobile
Inc., a global leader in mobile security services.

On one hand, users should always be cautious whenever downloading an app
to their phone, downloading applications only from trusted sources, reputable
application stores and markets. Users should always check reviews, ratings
and developer information before downloading. On the other hand, carriers,
app stores and download sites should take effective measures to protect users
from risks beforehand.

As a leading mobile security service provider, NetQin not only provides
anti-virus services in SaaS model to protect mobile users from the latest
security threats, but also cloud scan services built on cloud computing
technology to help app stores and download sites scan and verify all uploaded
applications to ensure that no security threats are embedded. The Mobile
Market of China Mobile has deployed NetQin Cloud Scan to protect their users
from potential security threats.

More than that, the proprietary "Cloud + Client" double engine enables
NetQin to identify mobile security threats much faster and respond to
security threats within 24 hours. The cloud scan detects and monitors threats
at the user end and the carrier's gateway as well as the download site app
stores, and then reports to the server for analysis, the result of which adds
to the most comprehensive security repository and this in return increases
the virus detection ability. Essentially, the larger the user base, the more
contribution to the virus database, the stronger service ability, and vice
versa.

NetQin Mobile Anti-virus for Android is FREE to download at:
