My server have been hammered all day by this supposed bot "QihooBot 1.0". I check Google, Yahoo, MSN and there are no results for this search term.
Qihoo is a search engine from China, and as such the traffic numbers are large sometimes from them. Qihoo are getting ready to release a new search engine also, however that is not 1.0. Hope that helps! http://www.qihoo.com/
