We have checked the paid for use that controls advertisements and we have several million view remaining on our account.We have had other independent users login and not logged in verify that they do not have pop up advertisements. We have been thorough and have not found a pop up advertisement yet? They do not ever appear when we login under our PCs and thus we have taken this outside to 3 other users, one who is not a BCB owner and not a user of Yuku. Please check the settings on You PC and contact Yuku direct on what you are seeing. They may have a Trojan horse in their system and they would want to know. If so then we will need took now also and address this with them ourselves. Please let use know what is advertised, how and when. BCB
