URL:Blacklist warning on every page

Hello!

I just opened my computer for the first time since yesterday and now it gives me an URL: Blacklist warning on every website I go to. It doesn’t prevent the pages from loading, the warning just pops up every time I go somewhere. Even on this forum. I clicked on the forum page and the notification popped up. I clicked on ‘Start new topic’ and the warning popped up again. It just keeps popping up and is very annoying. What might be wrong? For reference, I’m using Google Chrome and the problem doesn’t appear on Firefox. See screenshot (it also pops up on Google searches. It pops up everywhere).

Ok, so it didn’t attach the screenshot. Don’t know how to do that.

Okay, so here’s the screenshot.

Seems to be a medisharing site https://www.virustotal.com/gui/url/f2107b3c62ef4ba7bdfc5aa3365008eb3a37aaca4c14c8fcf3c68df12c5ed5b7/details

URL seems to be down https://downforeveryoneorjustme.com/conservational.mydiaconal.com?proto=https

have you tried to clear your browser surf history?

No, I haven’t. But the warning disappeared on its own. Might be because the site is down? But I’ll try to clear my history next time it might happen.
