NetQin Releases New Version 4.6 Beta of Anti-virus Application with New Cloud Security Technology and Real-time Monitoring

BEIJING, January 21, 2011 - NetQin, a global leader in mobile security services, today announced that
its Anti-virus v4.2 Beta security app, NetQin Mobile Anti-virus for Android
1.5/1.6/2.0/2.1/2.2, has been updated to provide a more comprehensive range
of security solutions for Android mobile devices. The application, which
features instant virus scan, contacts backup & restoration, and phone theft
and loss protection, now adds real-time monitoring and alerts, cloud
scanning, and a new-look intuitive interface to its functions, all of which
deliver an easy-to-use, fully protective mobile security application for
Android mobile users.

With mobile devices morphing from handheld phones to handheld
computers, users are constantly connected to a global and limitless
information center, which includes endless applications offering user
experiences from shopping and socializing to paying bills and managing bank
accounts. However, with openness comes added risks, and this exposes users to
a whole new realm of malicious security threats. NetQin Mobile Anti-virus for
Android V.4.6 completely protects a user's mobile device, data, and lifestyle
no matter the channel of communication - work or personal, email or SMS,
photo sharing or social networking.

Key new features include:

    -- Cloud Scan: v.4.6 Beta includes "cloud + client" twin-engine scanning,
       which is faster and more accurate at identifying and resolving
       threats from viruses and malicious programs. Key benefits include fast
       response to the latest security threats and comprehensive protection
       from Trojans, malware, and virus-infected plug-ins.
    -- Real-time monitoring and alerts: when users install a new application,
       the cloud will follow its safety procedures through real-time
       monitoring, and immediately notify the user if prompt deletion is
       needed.

"Malware and malicious content are only part of many mobile
security issues that need to be dealt with," said Dr. Lin Yu, CEO and
Co-founder of NetQin. "New threats, including those that compromise a user's
data or privacy, have emerged, and this is why we are constantly updating our
mobile Anti-virus products."
