Babylon Search has taken over my browser

Does anyone know how to remove Babylon Search?  I've tried everything.  I removed anything I could find that might be related to it in "add/remove programs".  I've ran spybot, norton, everything I have and I can't figure out what else to do.  It keeps popping up no matter what I do.  I downloaded Norton's power eraser and that did nothing.  I read that it's very difficult for a regular person to safely remove this on their own.  Is it possible?  Has anyone been hijacked by this malicious software and knows what to do?
