Quick Note Before You Begin

Before diving into the fixes, it’s important to check a few things that might save you time:

  • Restart your computer: Sometimes, a simple restart can clear temporary glitches causing the error.
  • Check for Windows Updates: Ensure your Windows 11 is up to date, as updates often fix system bugs.
  • Close unnecessary programs: Having many applications open can cause conflicts. Close all except what you need.
  • Verify your antivirus software: mfevtps.exe is related to McAfee security software. Ensure your antivirus is properly installed and updated.

Step 1: Identify What mfevtps.exe Is

The mfevtps.exe file is part of McAfee’s antivirus software. It helps with real-time scanning and protection. If this file becomes corrupted or conflicts with other programs, it can cause errors.

Knowing this helps because fixing the error often involves working with your McAfee software or its settings.

Step 2: Run a Full System Scan with McAfee

Running a full scan helps detect and remove any malware that might be affecting mfevtps.exe or your system files.

  1. Open your McAfee antivirus program.
  2. Navigate to the Scan section.
  3. Select Full Scan instead of a quick scan.
  4. Start the scan and wait for it to complete.
  5. Follow any instructions to remove or quarantine threats.

This step is important because malware can damage or mimic essential files like mfevtps.exe, causing errors.

Step 3: Repair or Reinstall McAfee Software

If scanning doesn’t fix the problem, your McAfee installation might be corrupted. Repairing or reinstalling McAfee can restore missing or damaged files.

To Repair McAfee:

  1. Press Windows + I to open Settings.
  2. Go to Apps > Installed apps.
  3. Find McAfee in the list.
  4. Click on McAfee and select Modify or Repair (if available).
  5. Follow the on-screen instructions to complete the repair.

If Repair Option Is Not Available, Reinstall McAfee:

  1. Uninstall McAfee from the same Installed apps section.
  2. Download the latest version from the official McAfee website.
  3. Run the installer and follow setup instructions carefully.
  4. Restart your computer after installation is complete.

This ensures your antivirus software is fully functional and not causing the error.

Step 4: Check for Conflicting Software

Sometimes, other antivirus or security programs can conflict with McAfee and cause errors like the one involving mfevtps.exe. Having multiple antivirus programs running simultaneously can cause system instability.

To check and fix conflicts:

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Look for other antivirus software running in the Processes tab.
  3. If found, consider disabling or uninstalling the other antivirus temporarily.
  4. Restart your computer and check if the error persists.

Running only one antivirus ensures smooth operation and fewer software conflicts.

Step 5: Use System File Checker (SFC) to Repair Corrupted Files

Windows has a built-in tool to find and fix corrupted system files, which might also affect mfevtps.exe.

  1. Press Windows + S, type cmd, right-click on Command Prompt, and select Run as administrator.
  2. In the command window, type the following and press Enter:
sfc /scannow

This scan will take some time. If any corrupted files are found, Windows will attempt to repair them automatically.

After the scan completes, restart your PC and check if the error still appears.

Step 6: Perform a Clean Boot to Isolate the Issue

A clean boot starts Windows with only essential drivers and startup programs. This helps identify if a background program is causing the error.

  1. Press Windows + R, type msconfig, and press Enter.
  2. In the System Configuration window, go to the Services tab.
  3. Check the box for Hide all Microsoft services.
  4. Click Disable all.
  5. Go to the Startup tab and click Open Task Manager.
  6. In Task Manager’s Startup tab, disable all startup items.
  7. Close Task Manager and click OK in System Configuration.
  8. Restart your computer.

Check if the mfevtps.exe error still occurs. If not, one of the disabled programs might be causing the problem. You can enable them one by one to find the culprit.
