Are all Norton safe sites or norton secure sites really secure

I have been wondering this for a while because I once wanted to go to brothersoft.com but I like to look at what people say and allmost all of the people say it is a virus infected website. I didn't try it myself, but norton says it is safe. So can I trust what norton always says. This would really help because I want to go to pogo.com, but people say you get viruses from that website and many people talk about the same way to get the virus so I am not so sure. Any help is welcome.
