First identify a website notification
Website notifications are small messages issued through your browser's notification permission system. In Microsoft Edge they can appear on the desktop even while the browser is closed. They are different from pop-up windows that open inside a tab, operating-system notifications and messages from a particular app. Notice the website or browser icon attached to the alert before changing settings. If a notice claims your computer is infected and demands immediate payment, do not click its buttons or call a phone number shown there.
Block notifications from Chrome on a computer
Open Chrome, choose the three-dot menu, then Settings → Privacy and security → Site settings → Notifications. Review the list of websites allowed to send notifications. Select or remove permission for unwanted sites and consider a quieter default prompt for future requests. You can usually also manage a particular site's permission from the icon beside the address bar. Blocking notifications from a domain does not delete its cookies, browser history, saved passwords or bookmarks; those are separate browser settings.
Stop unwanted notifications in Microsoft Edge
Open Edge and go to Settings → Privacy, search, and services → Site permissions → All sites, then choose the domain that keeps sending alerts. Change Notifications to Block. Microsoft's menu layout may change with Edge updates, so search Settings for site permissions if the wording differs. You can also visit the website, select the site-information icon beside the address bar and block its notifications there. Closing Edge or silencing Windows alerts may hide symptoms but does not revoke the site's permission.
Manage Chrome site alerts on Android
On an Android phone, open Chrome → three dots → Settings → Site settings → Notifications. Turn off site notifications generally, or open individual site permissions to keep only useful ones. The exact system labels vary across Android versions and phone brands. If alerts continue, check the phone's Settings → Apps → Notifications section to identify whether they come from Chrome or another installed application. Do not uninstall all browser data to fix one noisy website; targeted permission changes usually suffice.
Avoid fake security warnings and repeat permission prompts
Some sites use misleading messages such as 'Click Allow to prove you are human' or 'Allow to continue the video.' Notification permissions are optional and should not be granted to untrusted websites. If you clicked Allow by mistake, return to the browser's permissions page and block the domain. Scareware messages that claim to be from an antivirus company are not reliable diagnostics. Verify device security through trusted installed software. Do not enter passwords into a notification pop-up, even if it resembles an account alert.
If the alerts keep appearing
Take a screenshot that shows the sender and note whether the message appears on the lock screen, in the system notification center or in a browser tab. Check browser extensions and installed applications if the source is not a website permission. A browser reset is a last resort and may remove useful settings.
