Ok, this is going for a while without much progress so let's break this problem down.
We know for a fact that this is not something from our side, as we do not require any add-on, plugins, or extensions, etc to visit. We have thousands of members visiting every day including people that helped in this thread and none reported such a thing so we know it's from your end.
How to tell? easy.
1. Use edge or explorer or any other browser and see if you can visit the site
2. Switch to incognito mode. Make sure Chrome is not running, and press win+R and type in the box chrome.exe -incognito
and then visit the site. Dont login, just see if you can come here.
If you are able to visit hassle-free by using either way then the issue is with one of the extensions.
All you have to do now is disable ALL extensions and come visit again. type this on the URL chrome://extensions/ and switch everything off, and restart chrome, and make sure you can visit here. After that enable extensions one by one and test visit till you get the error, and that will reveal the addon that causes issues. After that remove it or investigate why is it doing that if it's an extension you really need.
Of course, do what was recommended above and have a virus scan performed.
Lets us know but also keep in mind, there isn't much else we can do as the problem is in something you did and not from our site.
