Blocking website content

I am a diabetic and as such am a member of some diabetic communities. Norton is blocking some of the content on the sites and if I turn off the pop-up blocking, it allows pop-ups so I am losing either way. Also, some words are highlighted and underlined such as doctor or diabetic. I don't want the pop-ups but the help and content at the sites is very important to me. And I hate the words being highlighted. Please tell me how to fix it.
