Known malicious website

I received an e-mail from an association of which I am a member, inviting me to vote online in their annual general meeting, and providing a link to perform that vote. On clicking the link the next screen was a warning from Norton that the site to which the link led was a "known dangerous website". The web address of this screen was as follows:-

extension://bdaafgjhhjkdplpffldcncdignokfkbo/content/ui/blockedPage.html?originalURL=https://aa.virtual-meetings.online/login&reportURL=https://safeweb.norton.com/report/show?url=https://aa.virtual-meetings.online/login&ulang=en&blockPageType=malicious&continueToSiteURL=https://aa.virtual-meetings.online/login

I then telephoned the association and established that the AGM was being held and their e-mail was genuine. Now the Norton warning screen included a button whereby one could ignore the warning and proceed to the website. So I clicked on this button but the next screen was the same warning screen as before, with the exact same web address. Thus I had gone around in a circle. Is this caused by Norton or by the Association having the AGM?
