I'm not sure whether my post is to special, but may I list up QTS 360 modules:
HIPS: Those come in handy as soon as you've not an detection for a zero-day malware, by blocking the malware by noticing dangerous behaviour, such as Autostart entries, trying to amend files (photos etc), or just blocking it due to heuristic malbehaviour.
360 Cloud Scan Engine (fast detection of new threats)
360 QVMII AI Engine: kind of a whitelist according to their website
Speedup/Cleanup tools: They help you to remove Temp files, to deactivate unnecessary Startup entries, visualize your startup time on a graph... Pretty nice tools

The sandbox is rather spartanic... It did not work that well for me, I prefer ShadowDefender for real-time tests.
WiFi Security check: I can't speak on that, as it did not support my former routher neither the new one.
Patch up: Nice feature for all systems but Windows 10, kinda Windows Update feature, but get's the update packages you can download manually, too. It automatically scans for new updates and offers to install them.
360 Internet Protection: I've noticed this one in Internet Explorer as well as in Google Chrome. It helps you blocking malicious sites, also has a nice extra feature to scan sensitive areas of your PC automatically when entering online shopping / banking sites.
They have a nice Anti-Ransomware module, I think it is based on those HIPS.
I'm sure someone will lose some words on Avira and Bitdefender, their engines can be added manually to improve Qihoo 360 detection.
Please notice that Avira and Bitdefender will run in Real-time protection regardless if they're activated or not (as long as you installed them). They will only be off when performing manual scans [this is due to the "Security" mode setting, where maximum protection features are enabled). Thanks
@silversurfer for pointing that out
Qihoo has also some bonus software found at the Toolbox:
360 Connect is an App avaiable for iOS as well as Android, kinda remote connection to devices registered within the App. You can kick off scans, see the status... Did not try that one out so far.
I already mentioned the Patch Up feature (which is very nice).
Sandbox is also already mentioned.
System Backup Cleaner: Would be careful with that one, I think it clears up those Shadow copies.
Browser Protection: Very nice feature to lock down your browsers settings and help to save them from getting amended (e.g. Start Page, amendmends are blocked automatically).
Firewall: This downloads the free version of GlassWire. Made my computer laggy, although great UI.
Disk compression: In times of huge HDDs, I've never tried this one out - never change a running system
