Support for QQ will be added in avast 4.8.
My advice… start learning Chinese! ;D
I don’t think Pidgin http://www.pidgin.im/ has a German version either.
I found a german pidgin at chip.de - it looks nice, without any ads like icq >:(
While it is compatible with avast has been able to QQ, but Ghost software and 360 Zhuanshagongju still are in conflict with it, so there always wrong. And the Chinese mainland the Trojan and virus, identifying the limited capacity. I hope that Avast can pay more attention to the views of Chinese users, avast better for users in China used.
