A staggering 480 million smartphones in China have fallen victim to a malicious software malware in the first half of this year, almost equal to the total registered complaints in 2012.
More than 450,000 trojans, malware and malicious advertisement plug-ins were intercepted by a mobile security product in China, state-run news agency Xinhua reported.
Trojans intercepted on Android phones accounted for 97 per cent of the total.
The number of Chinese mobile phone users crossed a billion mark last year touching 1.11 billion users.
About 47 per cent of Chinese urban residents have smartphones, according to a report released by Google.
