Hi Roger,
I have no idea how this file arrived on my system, but if it is signed by Microsoft surely they must know what it does or it wouldn't be a .dll?
Will try out your freefixer this week-end and get back to you with my diagnosis.
Frank.

@Frank: This version of widevinecdmadapter.dll is digitally signed by Google and I think it is part of the "Widevine Media Optimizer"

If you would, please, let me know if/when you have further updates regarding this one. I don't know why, but it has me a little more than concerned.

Thanks so much.
Kevin

Frank is naive. Just because a .dll file was created and signed does not make it safe or not make it a performance hog. Furthermore I still remember the old Real.com program(The one I paid for) The one that spied on me and opened a back door for hackers. I do not much like Google spying on me. What I want to know is are they counting videos on their servers and tracking network performance from the client end or is this some nasty ad campaign related software designed to spy on my clicks outside of their own video servers. Also what kind of performance issues ? Is it scheduled to go off every so often?? That is what I want to know? Can this site provide any of those details. I do not have a lot of time to waste figuring out these things.
