I installed qihoo 360 on windows 10 and i didnt come with "keylogger protection" in the privacy protection section, but on windows 7 it did. Does qihoo 360 still come with keylogger protection??
I have seen this before with Windows 8/8.1 64-bit, were the Anti-Logger doesn't appear in the UI. It could be the same for Windows 10 64-bit. Have you contact Qihoo Support or Community pages?
