360 Total Security antivirus software

360 Total Security is a comprehensive internet security and system maintenance software suite developed by Qihoo 360. Originally launched in China, it has expanded globally as a freemium product that integrates multiple antivirus engines, including its own proprietary cloud-based engine along with licensed technology from third-party security vendors.

The product is primarily developed and maintained in China, where the parent company's engineering and cloud infrastructure are based. Over the years, it has become one of the most widely used security solutions in Asia and maintains a significant international presence through its global versions. The brand is owned by the Chinese internet giant 360 Security Technology Inc. (formerly Qihoo 360), which is headquartered in Beijing and listed on the Shanghai Stock Exchange.
