When the Chinese antivirus software company Qihoo 360 (QIHU +0.00%) recently launched its own search engine to compete with Baidu (BIDU 3.94%), which had been far and away the market share leader in Chinese search, many thought they wouldn't have a chance. But now that Qihoo has 9% of the market share and Baidu has seen its 80% erode away to 73%, the Chinese search giant is not happy. It's fired back by launching its own antivirus software, stepping into Qihoo's wheelhouse in the same way that Qihoo has done. In this video, Fool.com contributor Kevin Chen discusses what this means for investors, and whether or not it is a major event for these companies.
