Stuff I've read says it's safe, but if it's messing with your iPlayer then I'd get rid of it anyway.
I find that every time Adobe Acrobat or Flash updates, I acquire some more unwanted "stuff" that gets between me and what I'm trying to do. I'm close to removing everything Adobe.
Could it have arrived on your pooter via one of those updaters? Can you remove it via the Control Panel "Programs" function?
