How to get rid ofroaringe sound on videos on my mac?
I was adding a couple of videos to a play list on YouTube and I made the mistake of clicking on an icon in one of them. The sound on all the videos had been replaced by a weird sort of roaring sound (on all my videos not just the YT ones). I can't use the time machine to restore the settings because I haven't set up a backup. Has anybody any idea how I can get rid of this sound - I think it may be caused by a virus
