In January 2011, Qihoo claimed that it was the second most popular web browser in China (after Internet Explorer),[2] with 172 million monthly active users, 44.1% of Internet users in China.[3] The true figure is much lower (in the 2-7% range) according to multiple independent sources.[4][5] As of November 2014, the Qihoo browser is the 5th most popular browser in the United States.[6]
The high usage numbers are in large part due to the software being very difficult to uninstall. Furthermore, whenever a user attempts to install another browser, a warning pop-up claims that the new browser is unsafe and should not be run.[7][8]
