It can be a real bugger to get rid of. You have uninstalled it via add/remove programs, give this a go and see if it will work. Make sure it is not listed in “Extensions” or “Plugins. In Chrome, Go to the Wrench icon -> Tools -> Extensions. Uncheck “enabled” next to Babylon and then press the “Remove” button.
You must restart your browser for the changes to take effect.
And you will most likely have to set your home page to another default search provider.
Hope this is of help.
