Before you try to remove McAfee Agent manually, try to remove McAfee Agent using frminst.exe and the /forceuninstall switch:

IMPORTANT: If you incur errors when you perform the uninstall using the forceuninstall switch, follow the steps in the "Manual removal steps" section.
 

1. Disable McAfee services protection in VSE. NOTE: This step is only needed if VSE is installed.
   
   VSE includes an Access Protection feature that prevents McAfee services from being stopped. To successfully remove McAfee Agent, you must disable this setting either locally or using ePolicy Orchestrator (ePO). Do either of the following:
   
    
   If VSE is not managed with ePO

   1. On the affected computer, click Start, Programs, McAfee, VirusScan Console.
   2. Right-click Access Protection and select Properties.
   3. Deselect Prevent McAfee services from being stopped.
   4. Click Apply.
   5. Close the VirusScan console.
   6. Continue to step 2.

   
   

   If VSE is managed with ePO

   1. On the ePO server, open the ePolicy Orchestrator Console.
   2. Select the directory or computer level where you need to change the VSE policy.
   3. In the right pane, expand the VirusScan Enterprise policy.
   4. Click Edit beside Access Protection Policies.
   5. Click the Access Protection tab and deselect Prevent McAfee services from being stopped.
   6. Click Apply.
   7. Send an agent wake-up call to apply the changes, or wait for the next policy enforcement for the changes to take effect.
   8. Close the ePO console and continue to step 2.


2. Run the frminst.exe /forceuninstall command:
   1. On the affected computer, click Start, Run, and type one of the following commands:
      
      "c:\Program Files\McAfee\Agent\x86\frminst.exe" /forceuninstall
      Or:
      "c:\Program Files\McAfee\Common Framework\x86\frminst.exe" /forceuninstall
      
      IMPORTANT: The path varies depending on the version of McAfee Agent you installed, and whether you installed as an upgrade or clean installation. Use Windows Explorer to determine the correct path.​
       
   2. To remove McAfee Agent processes from memory and complete the deletion of files, restart the computer.

If this procedure fails, continue to the manual removal steps.

IMPORTANT: Your company group policies might block your attempts to edit the registry. If you receive an error "Access Denied" during the edit registry sequences below, you must contact your IT department.
