McAfee removal is different on Windows and Mac, and the standard uninstall often leaves behind files that slow your system down

Removing McAfee completely requires more than clicking uninstall. The program leaves behind registry entries on Windows and cached files on both systems that can interfere with other antivirus software or consume disk space. The cleanest removal uses McAfee's own removal tool, which deletes these leftover files automatically.

This guide covers the full removal process for both Windows and Mac. If you are switching to a different antivirus program, complete the McAfee removal before you install the new one — running two antivirus programs at the same time causes conflicts and slows your computer.

Key Takeaways

  • McAfee's official removal tool (MCPR.exe on Windows) deletes the program and its leftover files in one step, which a standard uninstall does not do.
  • On Windows, you must restart your computer in Safe Mode before running the removal tool, or the tool cannot delete all the files it needs to.
  • On Mac, you can uninstall McAfee through the Applications folder or use the McAfee removal tool if standard uninstall leaves files behind.
  • After removal is complete, restart your computer once more to clear any remaining processes from memory.

Remove McAfee on Windows using the official removal tool

The McAfee removal tool (MCPR.exe) is the fastest way to remove McAfee completely on Windows. Download it directly from McAfee's website, restart your computer in Safe Mode, and run the tool. Safe Mode prevents McAfee processes from blocking the removal.

Step 1: Download the McAfee removal tool. Go to support.mcafee.com in your web browser. Search for "MCPR" or "McAfee Consumer Product Removal tool". Click the download link for MCPR.exe. Save it to your Desktop so you can find it easily.

Step 2: Restart your computer in Safe Mode. On Windows 10 or 11, click the Start button, type "msconfig" and press Enter. Click the Boot tab. Check the box next to "Safe boot" and click OK. Your computer will restart into Safe Mode, where only essential Windows files load.

Step 3: Run the removal tool. After your computer restarts, go to your Desktop and double-click MCPR.exe. A command window will open and begin removing McAfee. Do not close this window — let it run until it finishes and closes on its own. This usually takes 5 to 10 minutes.

Step 4: Restart your computer normally. After the removal tool closes, restart your computer. Go back to msconfig, uncheck "Safe boot", and click OK. Your computer will restart in normal mode. McAfee is now completely removed.

Remove McAfee on Windows through Settings if the tool does not work

If you cannot download the removal tool or it does not run, you can uninstall McAfee through Windows Settings. This method leaves some leftover files, but it removes the main program.

Step 1: Open Settings. Click the Start button and type "Settings". Click the Settings app to open it.

Step 2: Go to Apps. Click "Apps" in the left menu, then click "Apps and features".

Step 3: Find and remove McAfee. Scroll down the list until you see McAfee Total Protection, McAfee LiveSafe, or another McAfee product. Click it once to select it, then click the "Uninstall" button. A window will pop up asking you to confirm. Click "Uninstall" again.

Step 4: Complete the uninstall wizard. Follow the prompts in the uninstall window. When asked whether you want to remove all McAfee files, click "Yes". When the wizard finishes, click "Finish" and restart your computer.

Remove McAfee on Mac

On Mac, McAfee uninstalls more cleanly than on Windows because macOS does not use a registry system. You can remove it through the Applications folder or use McAfee's removal tool if files remain.

Step 1: Open Applications. Click the Finder icon in your dock. Click "Applications" in the sidebar on the left.

Step 2: Find McAfee. Look for McAfee Total Protection, McAfee LiveSafe, or another McAfee product in the Applications folder. Click it once to select it.

Step 3: Move to Trash. Press Command+Delete, or right-click the McAfee icon and select "Move to Trash". Enter your Mac password if prompted.

Step 4: Empty Trash. Click the Trash icon in your dock. Click "Empty" in the top right corner. McAfee is now removed.

If you want to remove leftover McAfee files, download the McAfee removal tool for Mac from support.mcafee.com, double-click it, and follow the prompts. Restart your Mac when finished.

What to do if McAfee will not uninstall

If the uninstall wizard hangs or closes without finishing, McAfee processes may be running in the background and blocking the removal. Restart your computer and try again. On Windows, make sure you are in Safe Mode before running the removal tool.

If the removal tool itself will not run, your antivirus software may be blocking it. Temporarily disable McAfee's real-time protection before running the tool. Open McAfee, look for a settings or protection menu, and toggle off "Real-time scanning" or "Protection". Then run the removal tool again.

If you still cannot remove McAfee, contact McAfee support directly at support.mcafee.com or call their phone support line. They can provide a custom removal tool or walk you through the process over the phone.

Install a new antivirus program after McAfee is removed

Wait at least 15 minutes after removing McAfee before you install a different antivirus program. This gives your computer time to clear McAfee processes from memory. If you install a new antivirus program too quickly, the two programs may conflict and cause errors.

Download your new antivirus program from the publisher's official website, not from a third-party download site. Run the installer and follow its prompts. Restart your computer when the installation finishes. Your new antivirus program will begin protecting your computer on the next restart.

Frequently Asked Questions

Will uninstalling McAfee leave my computer unprotected?

Yes, your computer will have no antivirus protection after McAfee is removed. Install a replacement antivirus program as soon as the McAfee removal is complete. Windows 10 and 11 include built-in antivirus called Windows Defender, which activates automatically if no other antivirus is installed.

Can I just delete the McAfee folder from my computer?

No. Deleting the folder manually leaves registry entries on Windows and system files on Mac that can cause problems. Use the official removal tool or the uninstall wizard instead — they remove all the pieces at once.

Why does my computer run slower after I uninstall McAfee?

Leftover McAfee files or processes may still be running. Restart your computer after uninstalling. If it is still slow, download and run the McAfee removal tool (MCPR.exe on Windows) to delete the remaining files.

Do I need to restart my computer after removing McAfee?

Yes. Restart your computer after the removal is complete. This clears McAfee processes from memory and ensures the removal is finished before you install a new antivirus program.

What if I want to reinstall McAfee later?

You can reinstall McAfee at any time by downloading it from mcafee.com or from your antivirus account page. Sign in with your McAfee account, download the installer, and run it. You will need an active subscription to use McAfee after installation.
