Qihoo

Qihoo, more commonly known by its brand name 360 Security Technology Inc., is a Chinese internet security company rather than a traditional mobile hardware manufacturer. Founded in June 2005 by Zhou Hongyi and Qi Xiangdong, the company is headquartered in the Chaoyang district of Beijing. While Qihoo has not established a significant presence in the market for manufacturing physical Android devices, it has played a notable role in the mobile software ecosystem. The company is best known for developing security and utility applications, including the antivirus programs 360 Safeguard and 360 Mobile Safe. Additionally, Qihoo created the 360 Secure Browser and the 360 Mobile Assistant application store, which have served as key distribution and security channels for mobile users in China.
