Android Question

my Samsung galaxy s3 was just updated....and now when friends send me links, whether internet or twitter, it opens to a default internet page, a bestbuy page that says "sorry the page you requested was not found". The internet icon disappeared, but I installed Google Chrome and so at least now I can get on the internet. But I want to be able to open things people send me. Is there a setting I need to fix? or something I can do to get my factory internet back?
