If you have ever had a McAfee product installed on your computer, run the McAfee Consumer Product Removal (MCPR) tool to clean up any old files.
IMPORTANT:

  • Always download a new copy of MCPR before each use.
    This ensures that you have the latest version, and that newer McAfee products can be successfully recognized.
  • MCPR cleans up only the components needed for reinstallation. It is not designed to clean up 100% of components.
  • Completing this step requires a restart.

Before you start:

  • Bookmark or favorite this article so that you can easily get back to it.
  • Save all open files.
  • Close all programs.
  1. Download the MCPR tool.
  2. Double-click MCPR.exe.
  3. If you see a security warning:

    Click Yes, Continue, or Run (depending on your version of Windows):

  4. At the McAfee Software Removal screen:
    1. Click Next.
    2. Click Agree to accept the End User License Agreement (EULA).
  5. At the Security Validation screen:
    1. Type the characters exactly as shown on your screen. Validation is case-sensitive.
    2. Click Next. This step prevents the accidental use of MCPR.

  6. When the process is complete, you see one of the following messages. Click the one that you see.

If you see this message, the MCPR tool has completed successfully.

  1. Restart your PC to complete the removal process.

    IMPORTANT: When your PC restarts, it will not be protected from viruses and malware. Ensure that you reinstall your security software as soon as possible to remain protected.

If you see this message, the cleanup did not go as planned:

  1. Restart your PC and run MCPR again.
  2. If you see Cleanup Unsuccessful again, ignore it.
  3. Restart your PC again.
  4. Attempt to reinstall your McAfee software.

If you are still unable to install:

  2. Let the agent know:
    • MCPR produced a Cleanup Unsuccessful message.
