Hello! I am currently active in a discussion on a Swedish Mac forum. (http://forum.macworld.se/topic/156831-vad-aer-widevine-media-optimizer-foer-program/) We are a few people who has encountered a strange update request. We are getting a dialog box with the text: "Widevine Media Optimizer Update Available" and then the options "Later" och "Update". Se pic: http://forum.macworld.se/uploads/monthly_03_2013/post-54600-014574700 1363958215_thumb.png The dialog box looks like crap and no one can recall having installed this applications. This makes us suspicious to as what this really is. Some people claim that it is nothing, and some claim it is a virus. ClamXav doesn't detect it. Anyhow we are unable to sort this out. All the information on it seems very contradicting. Any ideas?
