🔧 Step-by-Step Guide to Fully Uninstall McAfee

---

✅ Step 1: Disable McAfee Self-Protection Before Uninstalling

McAfee protects itself by default, preventing unauthorized removal. You must disable its self-protection module first.

Steps:

1. Open McAfee Security Center
2. Go to:

   Settings > General > PC Security

3. Look for:

• Real-Time Scanning
• Access Protection
• Self-Protection Module

3. Temporarily disable these features

⚠️ Note: If McAfee is unresponsive or frozen, skip to Step 3 or use Safe Mode

💡 Tip: Some versions allow disabling via Task Manager > Startup tab

---

✅ Step 2: Uninstall McAfee via Windows Settings

This removes the primary components but does not delete all traces.

Steps:

1. Press Windows + I to open Settings
2. Navigate to:

   Apps > Installed apps

3. Search for “McAfee”
4. Click on each entry and select Uninstall
5. Follow prompts and restart when done

⚠️ Note: Some entries may be grouped under “McAfee Security” or “McAfee LiveSafe”

💡 Tip: Reboot after uninstallation before proceeding to ensure file handles are released

---

✅ Step 3: Run McAfee’s Official Removal Tool (MCPR.exe)

To eliminate leftover files, services, and registry keys, McAfee provides an official Malicious Software Removal Tool (MCPR).

Steps:

1. Download MCPR.exe from the official McAfee website:

• https://www.mcafee.com/support/consumer/my-account/uninstall

1. Save the file to your desktop
2. Right-click > Run as Administrator
3. The tool will:

• Scan for McAfee components
• Remove remaining services, drivers, and registry entries

1. When complete, reboot your system

⚠️ Warning: Do not interrupt the process—this can leave the system unstable

💡 Tip: Run this tool even if you already uninstalled McAfee manually—it cleans up hidden remnants

---

✅ Step 4: Manually Remove Leftover Services and Drivers (Advanced)

Some versions of McAfee may leave behind system services or drivers.

Steps:

1. Press Windows + R, type:

   services.msc

2. Scroll through and look for any McAfee-related services:

• e.g., McAfee Framework Service, McShield, MfeVtps

2. Right-click each service > Stop, then set startup type to Disabled
3. Open Device Manager (devmgmt.msc)
4. Expand:

• Non-Plug and Play Devices
• Other Devices

2. Uninstall any remaining McAfee drivers

⚠️ Warning: Only remove services/drivers you are certain belong to McAfee

💡 Tip: Use fltmc to list filter drivers:

fltmc | findstr /i mcafee

---

✅ Step 5: Clean Up Remaining Files and Folders

Even after uninstalling, McAfee may leave behind directories and logs.

Common Paths to Delete:

C:\Program Files\McAfee\
C:\Program Files\Common Files\McAfee\
C:\ProgramData\McAfee\ (hidden folder)
C:\Users\Public\Public Documents\McAfee\
C:\Windows\System32\drivers\Mfe*.sys

Steps:

1. Open File Explorer
2. Paste each path into the address bar one at a time
3. Delete the folder (if exists)

⚠️ Note: Some files may be locked—use Unlocker or Process Explorer to release them

💡 Tip: Use CCleaner or Revo Uninstaller for deeper file/folder cleanup

---

✅ Step 6: Remove McAfee from the Registry (Advanced)

⚠️ Warning: Editing the registry incorrectly can cause system instability. Always back up before making changes.

Steps:

1. Press Windows + R, type:

   regedit

2. Backup the registry:

• File > Export > Save as Registry_Backup.reg

2. Navigate to:

   HKEY_LOCAL_MACHINE\SOFTWARE\McAfee

4. Delete the McAfee key
5. Also check:

   HKEY_CURRENT_USER\Software\McAfee
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\McAfee*

6. Delete any McAfee-related keys

⚠️ Note: Be extremely careful—do not delete unrelated keys

💡 Tip: Use RegScanner or Wise Registry Cleaner to locate orphaned entries

---

✅ Step 7: Verify No McAfee Processes Are Running

After uninstallation, verify that no McAfee components are still active.

Steps:

1. Press Ctrl + Shift + Esc to open Task Manager
2. Go to the Processes tab
3. Search for any entries containing:

• mcafee, mfetray, mfsystray, mfevtps

1. End tasks if found

⚠️ Note: Ending critical processes may cause temporary UI issues but won’t harm the OS

💡 Tip: Use wmic to list running McAfee processes:

wmic process where name like "%mcafee%" get ExecutablePath,CommandLine

---

✅ Step 8: Check for McAfee in Group Policy (Enterprise Environments)

In managed environments, McAfee may be enforced via Group Policy.

Steps:

1. Press Windows + R, type:

   gpedit.msc

2. Navigate to:

   Computer Configuration > Administrative Templates > System > Logon

3. Look for policies related to McAfee startup scripts or enforcement
4. If found, contact your IT administrator to remove them

⚠️ Note: Modifying GPOs without permission can violate company policy

💡 Tip: Use rsop.msc to see applied policies affecting McAfee behavior
