Hi, I have a new iMac and brought it home. Its connected to my network fine, but anytime I try to open up chrome or firefox it brings up wildblue.com internet network service. I can't navigate away from it. When I try to reset my home page it doesn't matter, it will still try to bring this up? Is this some kind of virus somehow on my mac? Never seen anything like it. I'm using comcast for my internet service provider currently. Thanks for any and all help.
