Thanks gobbly and Rosary for your comments. from the following I don't think they are that far behind...
While Baidu’s new app is a challenge to other free antivirus companies around the world, it’s what the app doesn’t do yet that’s more significant. This app is not available in Chinese right now, but it surely will be at some stage. Perhaps this overseas launch is a testing ground before releasing it in Baidu’s home market. When it is made available, Baidu Antivirus will mark a new front in the increasingly intense battle between Baidu and local rival Qihoo..
Rosary: The question I asked is what effect will Baidu's entry into Qihu's strength will have on qihu future?
Dont spend to much time on Antivirus segment. The major thing for QIHU is to grab more shares from BIDU on search engine market. Thats a cash cow business. Their monetized revenue will show up on next quarter. QIHU is a strong bu and the big guys know about it its 20% short in the stock. so it is nice to see some pullback for them to cover their shorts otherwise they will be trapped big time.
