a free upgrade from XP to 10 (China only).
By the way, I always wonder why people insist on buying AV? Free AV provides mostly better detection and even performance (less bloatware), then their paid counterparts. I guess, people do not trust free.Via Qihoo's update tool, Qihoo users in China will be able to upgrade their current Windows systems to Windows 10 - the newest version of Microsoft's operating system which is planned to be released this Summer. In addition to the free upgrade from Windows 7, 8 and 8.1 offered by Microsoft, this agreement makes all Qihoo users on Windows XP eligible for Windows 10.
