Start with this check.
Do not click the alert. Read its domain and independently open Chrome Settings → Privacy and security → Site settings → Notifications to review permission.
Do not call numbers or install cleaners advertised by an alert. A page claiming to detect viruses should not decide what software you install or who gets remote access.

Let’s go step by step.
0 of 5 checks completedMark each check to keep track during this visit.
Identify the sender without opening the ad
Read the app name and domain visible in the notification. If taking a note or screenshot, exclude private messages. Distinguish a system notification from a card drawn inside a webpage.
The message text does not authenticate its sender. A familiar logo inside the ad does not establish its origin.
Open settings independently
Launch Chrome through its usual icon and open Settings → Privacy and security → Site settings → Notifications. Review allowed sites and find the recorded domain rather than a brand mentioned in the message.
If absent, check whether another browser or profile sent the alert before removing unrelated permissions.
Block the unwanted site
Set the identified website’s notification permission to blocked. Keep permissions for services you use. You do not need to allow all notifications or revisit the advertisement to remove access.
Watch for new alerts from that domain. Old notifications may remain visible until dismissed.
Separate pop-ups from notifications
If the issue appears only in a tab, close it without following download buttons. If browsing repeatedly opens windows or redirects, record the page and review browser security help.
Blocking notifications does not remove every advertisement displayed as webpage content.
Review what happened earlier
Record whether you only allowed alerts or also installed software, shared credentials or granted remote access. The latter cases need a review of the program or account; do not consider them resolved merely because alerts stopped.
The alert disappearing confirms a permission change, not the security of the entire computer.
When to stop and ask for help
If you installed software or granted remote access through the alert, use official system or organisational support. If you entered a password, review that account from a trusted device.
Does a step differ from what you see? →Common questions
Does a virus notification prove infection?
No. Its text may be deceptive advertising. Identify the sender and the actions you took.
Is closing Chrome enough?
This guide checks removal of the website permission. Closing a window does not replace that review.
Will blocking the site delete emails?
This changes its browser alerts, not account contents. You will stop receiving notifications from that site.
