Qihoo 360 is a Chinese company that offers a free antivirus containing 3 antivirus engines (their engine, Avira and Bitdefender)
After several years in Chinese and English version, Qihoo has made a version in French version.
The editor offers a suite with antivirus and utilities that we consider unnecessary (Windows Update, cleaning etc) and an ESSENTIALS version that only content the antivirus.
On phishing, Qihoo makes a fiasco by blocking only one link.
On the files (URL and pack) the program is doing well and reacts correctly.
Unfortunately, it is very indented on Ransomware and Screenlocker attacks.
ZeroLocker's Roost that blocks the system, the system is infected, Windows Explorer crashed (which was committed by a 2nd pack malware), and the Scorpion Ransomware completes the test.
Can not start Windows, a repair is required.
Qihoo is not bad, far from it, but it is not the best either, recommend it for careful use.
