(I am a Chinese Junior high school students.And my English is not very well.So I have some troubles in my posts.) I have seen some posts about some Chinese AVs,like Rising, Jiangin, Kingsoft, Twister and so on.I want to tell you some about them. Rising has the highest share in China.It has over 80 million Chinese users.Followed by Kaspersky，Norton and so on.Jiangmin and Kingsoft ever had the second and third share in China.But now,they don't. Twister has many fans in China.But nobody know its exact share.It is like a dark horse.And also, it has great futures.Twister V8 will release soon. Rising 2010 beta has released.Acording to the test,it has some changes.But download the 2010 beta is difficult. Jiangmin had free edition just now.you can google for it. Kingsoft is famous for its office software.But its AV is good as well.Its cloud system is fast.You can have a try. OK,my English is limited.So I can't tell more.
