When did you notice

Safari preferences → remove all websites from having permissions to deliver notifications, can't remember exactly where it is there but it's a start to finding it.

Sorry, but you *have* gone to some weird sites, and you said yes when they asked you if you wanted notifications from them.

For everyone saying this is a virus, its not, OP just accepted notifications from a site

It is just push notification of some spammy website you have allowed to show notifications. Just clear cache and cookies for all time. It will go then.

You allowed a website to send you push messages. They use that to push you masters on your device or phone. It's mostly used for people to spam ads or fake virus stuff to get you to call a scam

You probably entered a page that invades you with SPAM, those messages are fake, your PC has no problem. Those messages are there to make you click on them and fill your navigation with SPAM.

If you want to have SPAM and ad-free browsing, I recommend installing an extension called AdGuard, it is completely free and will get rid of SPAM and invasive advertising. I have been using AdGuard for more than two years and It was the best decision I ever made. In just two hours of browsing, it can block more than 2000 elements.

Hi there! It looks like you’re getting scammy notifications from a website pretending to alert you about viruses. Here’s how to stop them: 1. Close the Website: If you’re seeing these pop-ups in your web browser (like Safari or Chrome), close the page immediately. Don’t click on the notifications.

You got std’s my dear
