Research notes

Origin: 360 Safeguard (360安全卫士) launched July 17, 2008 and became China's dominant free security suite; 360 Total Security was announced at MWC Barcelona on Feb 25, 2014 as a free, rebuilt international version shipped in 15 languages.
Qihoo's own Feb 2015 release PR claimed technology 'serving over 550 million PC users worldwide'; that v6.0 release added multi-user and non-administrator support for shared PCs.
Multi-engine marketing: up to five AV engines including licensed Bitdefender and Avira plus the in-house QVM II 'AI' engine, bundled with optimization tools (Cleanup, Speedup, Patch Up, Wi-Fi Security Check, sandbox).
Qihoo 360 was added to the US Commerce Department Entity List in May 2020 over alleged Chinese-military ties - a sanctions-adjacent listing on the vendor, not a finding about the app itself.
MS Store manifest declares capability: internetClient (the only declared capability on the store build).

Announcements

Feb 5, 2015 Press release — Qihoo 360 Released a New Version of 360 Total Security by u/qihoo-360

Earliest vendor promotion found - the Feb 25, 2014 MWC launch itself was covered in Chinese tech press (163.com) rather than a vendor post.

The company is committed to making utility and security free and available to every internet user globally. — Problem statement
