Protection against ransomeware is notable and a place to start for Qihoo. They need to step up big, however, and bring a product that protects from all threats, not just ransomeware. Clearly, internet filtering needs to be ahem [added]. What they have might as well not even be there. Maybe also they could redevelop the secure browser and make it auto work with their sandbox or something along those lines.
360 is nicely written, but nags are too much for me at this point. Hope they get on the right track and come up with something special...
