Google chrome keeps crashing, help?

[Kit]

I downloaded something for a project for school, and with it, babylon was added. I think that this is the cause of google chrome crashing. It also took hold of firefox's search engine, and i cant even get onto internet explorer anymore...and every time I open chrome, I get a message saying "whooa, google chrome crashed, reload?". I uninstalled babylon with CCleaner, but chrome still keeps crashing, and firefox's search engine is still tooken held of from babylon. Please help
