Based on a quick search, this seems like some new advertising industry initiative, not some kind of malware. So unless there's something more to the story you'd like to share, it looks like basically sites that would normally have some kind of ad will start having this "AdChoices" branding on them.
Hello, been having a problem which I'm tired of trying to fix. I have Windows 7 OS and am finding adware called AD Choices on many web pages. I did do some internet research and checked the add ons as well as uninstall programs and find no listing of Ad Choices. Currently I have ran Malware Bytes and Spy Hunter. Both did not locate or removed Ad Choices. Any help is greatly appreciated.
