Looking at the code, it is using a script from Browser Update[1] to determine whether to show that message.

Here's the line from the js you linked to that checks the browser version:

    window.checkBrowserVersion = function() { i()({ required: { i: 12, e: -4, f: -3, o: -3, s: -1, c: -3 }, insecure: !0, unsupported: !0, reminder: 0, reminderClosed: 168, style: "corner", api: 2019.06, test: !1, onshow: function() { window.track && window.track("BrowserUpdate", "outdated_version_dialog", "Browser version outdated dialog") } }) }, $((function() { window.checkBrowserVersion() }));

The c: -3 is the crucial bit that should cause it to trigger if your version is at least 3 versions out of date.

Yours isn't though. Can you access http://browser-update.org ? If not, then there might be something with your DNS settings. Have you tried tethering through your phone? Have you changed your user agent?

1. http://browser-update.org/#install

Just checked, and my Chrome is on version 84. Version 80 is out of date.

You need to update Chrome.

You don't need to call an ambulance when you break your leg, but your browser has at least five high vulnerabilities (and one critical vulnerability).

That's interesting. Number of versions is probably a weak signal for this --- but how many browser versions should the dev a small site be looking for? Things DO break...

Are you sure it's malware? Looking at the code it seems to redirect to "browser-update.org" and is genuinely redirecting only older browsers based on unsupported features.
