Gobluetexas.com as on tv

I saw an ad on tv for medicare from BlueCross/BlueShield that said to go to gobluetexas.com; I tried to go there and Norton blocked it as an intrusion attack of high severity. I trust Norton

but couldn't find anything on the site about this one, using search of blogs & posts. Kinda wondering why a reputable company like BCBS would send me to a site for Medicare coverage that was an Intrusion. Maybe I got it wrong somehow but that site was definitely "bad" i.e. blocked. Does anybody know about this one??
