McAfee trying to invade my Win11 system

Question

I have Norton 360 as my antivirus on a Win365 machine. Recently I see McAfee trying to tell me to finish installing it. I don't want McAfee at all, but don't seem to be able to get into Apps to remove or prevent it from trying. What is my solution?

Hi John Janoski,

Thanks for post. I understand that you’re seeing McAfee prompts even though you’re already using Norton 360, and you’d like to stop McAfee from appearing or attempting to install. Have you already tried the Q&A Assist suggestions? In addition, please try the following.

Step 1 – Check Windows notification senders

1. Open Settings > “System” > “Notifications”
2. Scroll down to “Notifications from apps and other senders”
3. Look specifically for “McAfee” (or anything related)
4. Turn it Off

This stops prompts even when a full app is no longer visible under Installed apps.

Step 2 – Check startup entries

1. Press Ctrl + Shift + Esc to open Task Manager
2. Go to “Startup apps”
3. If any McAfee‑related entry exists > select it > Disable
4. Restart Windows

This could be a scam attempt and not be coming from McAfee itself.

Is this a pop-up you're receiving?

If so, could you share a screenshot so I can try to identify the source of the pop-up?

Use the shortcut "Windows + Shift + S" to use the screenshot tool. Be sure to censor any personal information. The Microsoft Q&A is public.

Looking forward to your reply so we can figure this out together.

The most likely cause is either:

• A preinstalled McAfee trial still on the system, or
• Fake “McAfee” alerts coming from a website or unwanted software.

Try these steps in order:

1. Check for real McAfee software and uninstall it
   1. Select Start > Settings > Apps.
   2. In Installed apps, look for anything named McAfee.
   3. If found, select it and choose Uninstall. Restart if prompted.
   4. After uninstalling any third‑party security apps, confirm that Microsoft Defender Antivirus and Windows Firewall are on so the device is not left unprotected.
2. If no McAfee app is listed, treat it as unwanted software or fake alerts
   • These can be:
     • Browser notification spam (websites sending “McAfee” style warnings), or
     • An unwanted app that was installed alongside something else.
   Do the following: a. Remove suspicious browser notifications
   • In the browser (for example, Microsoft Edge):
     • Open the browser settings and go to Site permissions > Notifications.
     • In the Allow list, remove or block any sites that are not recognized or that look suspicious.
   • Repeat for any other browsers in use.
   b. Remove unwanted apps
   • Go to Start > Settings > Apps again.
   • Look for unfamiliar apps (for example, unknown browsers or tools recently installed) and uninstall them.
3. Reduce the chance of similar unwanted software in future
   • Install apps only from trusted sources such as Microsoft Store.
   • Make sure a regularly updated antivirus product is running (Norton 360 in this case, or Microsoft Defender Antivirus if Norton is removed).
   • Keep Windows, browsers, and apps up to date.
4. Turn on Tamper Protection and keep Windows security features enabled
   • In Windows 11, ensure Tamper Protection is turned on so malware cannot change security settings.

If McAfee‑style pop‑ups continue even after these steps, run a full scan with the existing antivirus and consider using an additional reputable malware scanner to check for adware or potentially unwanted applications.
