Oracle recommends the Ask Toolbar when you install Java. Someone ought to drop in on Oracle and perform a random inspection. If a majority of (non-development) users [who have Java installed] are not also using Ask, at least one executive-level decision maker (i.e. not a peon) needs to be thrown in the slammer for fraud.
Haven't seen it, but if I encountered it I'd just try CCleaner to start with in the first place I haven't personally been unable to get rid of something with it yet since I began using it a few years back. Might need to use it in safe mode in some instances.
CCleaner is like the Swiss army knife for Cleaning your PC from stuff you don't need or want on it that doesn't need to be there in my experience with it thus far.
