If McAfee is not installed, the pop-ups are usually one of these:
- Browser notification spam from a website
- A malicious or unwanted browser extension
- Potentially unwanted software on Windows
Try this end-to-end cleanup:
- Check Edge notification permissions
- In Microsoft Edge, open Settings.
- Go to Cookies and site permissions > Notifications.
- Remove or block any site that is allowed to send notifications and is unfamiliar or suspicious.
- If needed, turn off the option that allows sites to ask to send notifications.
- Turn off Edge extensions temporarily
- In Edge, press Alt + F > Extensions > Manage extensions.
- Turn off all installed extensions.
- Test whether the pop-ups stop.
- If they stop, turn extensions back on one at a time to find the one causing the issue.
- Make sure Edge is up to date
- In Edge, press Alt + F > Settings.
- Go to About Microsoft Edge.
- Let Edge install any available update, then restart the browser if prompted.
- Scan for unwanted software or malware
- Use Windows Security / Microsoft Defender to scan the device.
- Unwanted software can cause excessive ads, browser changes, and hard-to-close pop-ups.
- Remove suspicious apps from Windows
- Go to Start > Settings > Apps.
- Review recently installed apps, especially anything not intentionally installed.
- Select suspicious apps and choose Uninstall.
- If the issue started recently, sorting apps by install date can help identify the cause.
- Check antivirus overlap
- Do not run multiple antivirus or antispyware products at the same time. That can make the PC unstable or restart unexpectedly.
- If an unwanted security product is installed, uninstall it from Start > Settings > Apps.
- Caution: after removing security software, make sure Microsoft Defender Antivirus is enabled and Windows Firewall is turned on.
- Turn on potentially unwanted app blocking
- Go to Start > Settings > Update & Security > Windows Security > App & browser control > Reputation-based protection settings.
- Turn on potentially unwanted app blocking.
- Enable both Block apps and Block downloads.
Useful signs that this is unwanted software rather than real McAfee include: apps that were never installed intentionally, changed browser settings, excessive device-health warnings, and ads that are difficult to close.
