I just came across this from Baidu who have just realsed the beta of version of their free antivirus. It is based on Kingsoft PC Doctor. But is being updated more frequently than Kingsoft's product. You can get it here: http://security.baidu.co.th/en/ You can also get it bundled with the free version of Avira http://www.avira.com/en/baidu-pc-faster I will try it out tonight. It looks interesting since it's been a while since Kingsoft released an update to PC Doctor.
