Products like Qihoo, Baidu, Kingsoft, Tencent and other of those copy-paste crap products. All of them have almost the same UI and if one changes something, the other follows immediately. They look almost identical, even the settings are in the same order... They all use about the same engines, which makes them not really adding much value to the industry in my opinion. Also way too many alerts, overreactive file collecting cloud, too many false positives, too many useless features with cool names but no single kind of extra additonal protection, ads that don't have anything to do with the antivirus and shady privacy policies. If I want to use Avira, Kaspersky or Bitdefender engine, I would go for the companies that really make them and not these ones.
