I have had a couple of customers complain that when they click on affiliate links, nothing happens. The one thing they both had in common was that they were AT&T customers. When the first person contacted me, he said he was getting a "this url is unsafe" warning. The second person says they are getting a blank window.

Does anyone know what software AT&T U-Verse is installing that causes affiliate links to be blocked? I am a U-Verse customer and have not seen this behavior. I did not install any u-verse software though, don't use their portal, don't use their e-mail, etc.
