When I go to click play button on 'progrock.com' a small red Pinterest popup appears and disappears, so it is difficult to avoid. If I accidentally click it a green box named 'Shopaholic' gives me a message 'Thanks for sharing'. I have cleared my browser cache and use Adblock plus. I cannot find any add ons or plug ins that are causing this. Please can you help me to get rid of it? I have never seen it before and I have been using this radio station for a long time. Thanks!
