I sent the email to the site earlier this morning. Since the site needs to be updated from yesterday, I would suppose they don't check everything every day. I don't particularly expect a reply anyway. What they need to do is check what they've got on the site for any unusual files or scripts and make changes. Given the nature of the site, I don't really expect that to happen anytime soon.
As for the people that don't get warnings from their antivirus. The results will be different depending on the operating system. Something that is a real problem with Windows isn't usually going to matter with Apple/Linux/Android and any good antivirus will know that. Just check that your antivirus is up to date. If it gives a warning after you've updated and didn't before, scan your computer.
