I occasionally import several hundred of our clients company names into Excel, which names are hyperlinked to an info page on the internet that lists their contact information. Whenever I do this and click on the link, a security message pops-up and warns me that "Microsoft Office has detected a potential security concern because hyperlinks are a security threat", and asks me if I want to continue or abort; I click "Continue" and it will not forward to the client's info-site anyway. Nothing happens.

How can I turn this nuisance off in Excel? Thanks!
