What is Mfevtps.exe & How to Fix its High CPU Usage?

We often wonder why resource consumption in Windows is high. One look at the Task Manager and a list of the processes and background tasks hogging the CPU and RAM will be available. When we talk of these, mfevtps.exe is one of the executable files that bother many. 

While some reported that the process led to error messages, others were concerned about security and privacy. And you have every reason to, given that there’s not much detail available on the security risk rating. Keep reading to find out all about mfevtps.exe!

What is the function of mfevtps.exe on your computer?

The mfevtps.exe process, linked to McAfee, Inc., stands for McAfee For Enterprise Validation Trust Protection Service. It is a core part of the antivirus and runs as soon as you boot the PC.

The primary job of the McAfee Process Validation Service, as the name suggests, is to examine the processes, programs, and DLLs on the PCs interacting with the McAfee, Inc. antivirus and verify whether these are safe.

While verifying the processes, McAfee creates a cache for the results. So, the next time a validation check is initiated, the McAfee Process Validation Service first inspects the cache for previous results, thereby reducing time and boosting the overall performance.

The file size is roughly 0.2 MB, and the file location is:C:\Windows\System32\mfevtps.exe 

For those wondering if the presence of the process can be due to malware infection. That’s not the case. It’s a legit McAfee Total Protection file.

What causes mfevtps.exe to use high CPU resources?

Here are the primary reasons you are facing high CPU usage due to the process:

• Corrupt cache: You may come across common mfevtps.exe errors when the cache created by the service is corrupt, often leading to high CPU usage, which will slow down the PC.
• Conflicts with Windows services: A few users discovered that the McAfee Antivirus process conflicted with Windows services, resulting in error messages.
• Third-party programs triggering the issue: Often, another third-party antivirus, security software, or the configured firewall may not work too well with the McAfee, Inc. software program, triggering such errors.
• Running an outdated version of the antivirus: Though unlikely, there’s the possibility that the McAfee, Inc. antivirus installed is outdated, which will affect its processes, as well as the performance of Windows.

How can I fix the high CPU usage caused by mfevtps.exe?

Tip

You shouldn’t disable or delete the mfevtps.exe process as long as McAfee is the primary antivirus, as it will affect the basic functioning of the software.

Before we move to the slightly tricky solutions, try these quick ones first:

• Restart the computer in case the CPU usage is extremely high, and you can’t perform any operation.
• Verify the file path and make sure you have the original file. In case of doubt, scan your PC for malware.
• Update both Windows and the McAfee LLC antivirus software.
• Boot Windows into Safe Mode once and then again into normal mode. This will clear the cache.
• Uninstall any conflicting applications. This also helps fix the Mcshield.exe high CPU usage.

If none work, head to the fixes listed next.

1. Whitelist the process in the firewall

1.  Press Windows + S to open Search, type Allow an app through Windows Firewall, and click on the relevant search result.
2. Click on Change settings.
3. Click the Allow another app button. 
4. Now, click on Browse.
5. Navigate the following path:C:\Windows\System32
6. Locate and select the mfevtps.exe file, then click on Open.
7. Next, click on Add.
8. Make sure both the Private and Public checkboxes are ticked for the process, and click on OK to save the changes.

Since the built-in Windows Defender Firewall is likely to trigger high CPU usage with mfevtps.exe, it’s recommended that you whitelist the process.

Do the same for third-party firewalls installed on the PC. Though the steps vary, you can find these on the program’s official website.

2. Make sure the relevant services are running

1. Press Windows + R to open Run, type services.msc in the search box, and hit Enter.
2. Locate the Cryptographic Services entry, right-click on it, and select Properties.
3. Choose Automatic from the Startup type dropdown menu, click on the Start button to run the service, and then on OK.
4. Once done, restart the computer.

That’s it! After starting the Cryptographic Service, things should be up and running, and you shouldn’t come across more instances of mfevtps.exe crash.

After uninstalling McAfee, you can either switch to the built-in Windows Security or use another popular antivirus solution.

How can I prevent mfevtps.exe from causing high CPU usage in the future?

To prevent any issues, follow these tips:

• Make sure all the program files work fine and none are corrupt. Corrupted files are often a source of errors and could lead to high CPU usage and RAM consumption.
• Verify that both the Windows operating system and the McAfee antivirus are updated. 
• Identify any corrupt operating system files and run the DISM tool and SFC scan to fix them. It may also fix things when Xagt.exe causes high CPU usage.

Are there other system processes that might cause similar high CPU usage issues?

Yes, several processes are known to consume a fair amount of resources in Windows. Some apps even do that under ideal conditions. So you shouldn’t be bothered, especially if it’s a game or editing software. The processes triggered by browsers also tend to hog the system resources.

Besides, a PC infected with malicious software, having too many autostart programs, or running a corrupt exe file extension, are all reasons behind increased CPU consumption. 

That’s all! By now, you should have fixed any problems with the McAfee software package and the mfevtps.exe process.
