With original double-engine technology, NetQin Mobile Anti-virus deletes
the latest viruses, Trojans, spyware and malicious fee-deduction software to
protect your phone and privacy. Real-time protection is also included to
detect threats and ensure device safety during file transmission, network
connection and app installation. With NetQin Mobile Anti-virus V4.0, a
firewall runs in the background to protect network traffic and privacy.

The "Anti-lost" feature of NetQin Mobile Anti-virus V4.0 runs with remote
control-like functions, providing worldwide protection for financial losses
and privacy leakage. "Anti-lost" allows users to locate a lost phone, sound
an alarm on the lost phone, and trace where exactly it is. If the user gives
up on the possibility of getting the device back, the content on the phone
can be completely deleted via simple remote commands sent to the phone.

Also featured in NetQin Mobile Anti-virus V4.0 is an account protection
feature which prevents account information (Ebank accounts, stock account, IM
accounts, etc) from leaking. It also prevents any sort of eavesdropping on
calls. These features are all specifically crafted to ensure total privacy
protection for users, and a complete sense of security in using their
respective devices.

NetQin Mobile Anti-virus V4.0 keeps users safe from viruses, and prevents
private information leakage. New features allow users to locate lost devices,
and if necessary, can also delete all content that was prior stored on the
device. Account protection was also added, along with an anti-eavesdropping
feature to ensure users are constantly being protected from privacy leakage.
