I think that the proxy suggestion is a red herring.
Now that you have given the URL, I have checked out the bloomberg.com home page and again no redirect, but there is one reference to newstogram.com in a script tag (see image), but that doesn't appear to be any redirection.
So I'm unable to find anything obvious on that page that might attempt a redirect, avast is quite good on malicious redirect attempts (usually inserted script tags, but not like this). Unless you are able to give a more specific page URL at blomberg.com, I can't see where the problem is.
