3. In the Apps list find the necessary software and right-click it.
4. On the pop-up panel click Uninstall.

5. In the Programs and Features window select McAfee.
6. The process uninstalling McAfee antivirus from your computer will start (the process may take a minute).

When uninstalling via Windows standard tools some files and folders of the previously installed antivirus programs may still reside in the system; that is why you are recommended to check the Program Files folder. If the Program Files folder contains any subfolders or files of the antivirus programs installed earlier, you are recommended to remove them. Then, try to install a Kaspersky Lab product once again.

If removal of McAfee antivirus was not successful and the Setup Wizard asks to remove incompatible software manually, use a special tool to remove McAfee products:

1. If McAfee Anti-Theft or Intel Anti-Theft service is enabled, disable the service before using a special removal tool.
2. Download the utility MCPR.exe (MCPR (C) McAfee, Inc). See how to download a file:
   • Under Windows 8
   • Under Windows 7
   • Under Windows Vista
3. Double-click the file MCPR.exe to run it.
4. In the McAfee Software Removal window, click the Next button.

5. In the McAfee Software Removal window, carefully read the license agreement, select Agree, and click the Next button.

6. In the Security Validation window, enter the characters from the picture into the empty field and click Next.

7. After uninstallation of McAfee you should restart your computer. In the Removal Complete window, click the Restart button to restart your computer.

If all remains of your previous anti-virus software were removed, or you have not had any anti-virus software installed on your computer, but you cannot install a Kaspersky Lab product, then create a request to Kaspersky Lab Technical Support via the My Kaspersky Account service. Attach to your request a report of the Getsysteminfo tool. In the request, give detailed description of the problem and the actions necessary to reproduce the problem.
