In desktop Chrome, open Settings > Privacy and security > Site Settings > Notifications. Review the sites allowed to send notifications and block the ones you do not want. A notification claiming your PC is infected is not proof of malware; do not click its buttons or call its number.
Do not install software or give remote access because a notification tells you to. Blocking a legitimate site’s notifications may also stop reminders you wanted, so review the site name rather than removing permissions indiscriminately.
1. Identify which kind of interruption you have
A website notification can appear at the edge of the desktop and may include the browser name and a site address. A browser popup opens a new window or tab. A banner drawn inside a page is part of that page. These are controlled differently, so notice where the interruption appears.
Write down the displayed website address without opening it. A familiar company logo, red warning background, or system-like wording does not establish that the message came from Windows or your antivirus. Sites can choose misleading notification text.
- Dismiss the notification using its ordinary close control. Do not use its Scan, Renew, Allow, or Call button.
- If the notice names a genuine security application, open that application yourself from Start and check its status independently.
2. Remove permission in Chrome
Open Chrome’s three-dot menu and choose Settings. Go to Privacy and security > Site Settings > Notifications. The address chrome://settings/content/notifications also opens this settings page when entered directly into Chrome’s address bar.
Review the allowed list. For an unwanted site, use its menu to choose Block where available. If the interface offers Remove instead, removing permission stops the existing grant but may let the site ask again; a block is clearer when you never want its notices.
- Check each Chrome profile you actually use if the permission is not in the first profile’s list. Profiles can have different settings.
- Choose a default that prevents sites from asking if you prefer no website notification prompts. You can deliberately allow a trusted site later.
- Close Chrome and reopen it, then wait to see whether the interruptions return.
3. Handle popups separately
If the problem opens tabs or windows, visit Site Settings > Pop-ups and redirects and review allowed exceptions. Remove or block an unwanted exception. Normal popup blocking may still allow a window opened after you click something, so a site’s behavior matters as well as the setting.
Do not interact with a fake warning to make it disappear. Close its tab. If a page prevents normal interaction, close the browser after saving other work where possible; ending it forcibly can lose unsaved forms. Avoid restoring the offending tab in the next session.
4. Check other sources if it continues
A remaining alert may come from a different browser, a second Chrome profile, an installed application, or an extension. Read the application name on the notice and check the corresponding settings. Muting all Windows notifications can hide the symptom while leaving the unwanted browser permission in place.
In Chrome, review Extensions > Manage Extensions. Disable an optional extension you do not recognize and investigate its publisher before deciding whether to remove it. On a managed computer, ask IT about unfamiliar organizational extensions.
- Update Chrome from Help > About Google Chrome.
- If the home page or search engine also changed unexpectedly, or unwanted programs appeared, follow the malware guide using trusted built-in tools.
- Do not assume that every unwanted notification means the computer is infected.
What if you already clicked?
Simply opening a page does not automatically prove account theft or infection. Close the page and consider what happened next. If you installed software, granted remote access, or entered a password, the response must address that specific action.
Change an exposed password through the real service on a trusted device, secure the account, and contact organizational IT if work information was involved. If you only allowed notifications, revoking that permission is the targeted first action. Keep protection proportional to the evidence rather than purchasing a cleanup service from the warning itself.
