Can't complete Two-step Login process

I’m trying to set up Two-step login for my account. I have Google Authenticator set up on my phone. But here’s where I get stuck: When I scan the QR code with my phone, I get a weblink which takes me to–for lack of better terms–spam sites, random surveys offering Amazon gift cards for answering a couple of questions, etc. I don’t get a code to complete the setup process. What am I doing wrong? Thank you for your help.
