Why are some of my customers getting "malicious site" warning when attempting to open a jotform?

Some are fearful to click "continue to site". On this page http://www.wmsga.org/index.php/tri-state/ if they try to open Tri State on-line or print app they get the warning. It has happened to me but I have confidence that your site is safe. How can we clear this up and give my customers confidence that all my forms are save?

FYI I use Noton Internet security as my firewall.

The link below  is a page is 99% Jotforms so you can see I really need my clients to feel safe.

This is an issue with our domain jotformpro.com, your form belongs to this domain. We have this issue a few days ago and we contacted Norton for whitelist process and upon checking, the issue is already resolved. You can check it here:

To fix it, please clear your browsers cache and cookies for Jotform. Advise the same method to your customers.

Thank you.
