HTC, the world's No. 5 smartphone maker, said on Monday it would triple its China outlets to 2,000 by end of this year from 650 now. The company, one of the largest manufacturers of Google's Android-based devices, is embroiled in an acrimonious patent war with Apple, and is also seeing its rapid growth slow in an increasingly competitive market.

U.S. computer security software maker McAfee said the number of malware targeted at Android devices jumped 76 percent since last quarter, making Android the most attacked mobile operating system.

This year we have seen record breaking numbers of malware, especially on mobile devices, where the uptick is in direct correlation to popularity, Vincent Weafer, senior vice president of McAfee Labs, said in a statement.

In the second quarter of 2011, Google's Android operating system-based malware surpassed Nokia's Symbian as the most popular target for mobile malware developers, McAfee, a unit of Intel Corp, said in a report.

The rapid rise in Android malware in Q2 indicates that the platform could become an increasing target for cybercriminals, McAfee said.
