Antimalware service executable is one of the common problems many Windows 10 users are having after an update. Many users have complained that they have upgraded from Windows 8 or Windows 10 to latest build version of Windows 10 and then they started to have Antimalware service executable high CPU issue. Unfortunately, Windows latest edition was a rushed project because they had to compensate Windows 8.1 Pro users a free upgrade.
What is Antimalware Service Executable?
I know that many of you have this question that what is Antimalware service executable? Why is it causing such a problem and why won’t Microsoft won’t fix it? Well, Antimalware service executable is a feature of Windows defender that helps you to fight against the Virus, Spamming, Malware, Adware, Trojans, etc. It is a built-in tool that scans for malware and eliminates any threats when found on your Windows 10 PC.
You cannot remove MsMpEng.exe or Antimalware service executable tool from your computer. But, Microsoft has provided a fix, and we will also suggest you few more things that will fix the high CPU and memory usage
First, we need the possibilities because it explains the reasons behind why your Windows 10 PC is lagging and slowing.
- Microsoft added a software or antivirus program called “Defender” that protects your Windows PC from all sorts of threats. The program runs in the background without interrupting your work or even when you’re PC is idle. The main purpose of the program is to identify the Virus, Malware, Adware, harmful files, etc. Now, it comes with an option called “real-time protection”, and it consumes a lot of memory and CPU. The “real-time protection” doesn’t stop until you manually stop it from protecting you from threats. If you are running an older machine like Dual-core manufactured below 2010, then Windows defender is real-time protection is slowing your PC down.
- Windows Defender has another feature called “deep scanning” that constantly keep scanning your drives for threats and it doesn’t stop until you turn off your PC. In case, if your PC has standard HDD storage and not SSD storage, then your computer will slow down because it consumes a lot of memory and CPU. In simple words, deep scanning slows your PC down, so you have to turn it off.
There are many reasons behind Windows Defender behavior, but we are going to show you ways that allow you to fix the problem.
The first thing you need to know that suppose Windows Defender is to keep scanning files back to back without a break, then this is a serious problem. However, on the flip side, if you are planning to reset the PC, then it will fix the problem temporarily.
There is nothing wrong with letting “msmpeng.exe” Antimalware service executable run in the background because it protects you real-time, and the good part is that you can fix it using Windows features.
Allow us to show you how to disable Antimalware Service Executable Windows 10.
1. Fix Antimalware Service Executable High CPU Windows 10
First, you have to identify the problem, so this will help you identify the problem and fix the issue at the same time. I have mentioned in the first reason that real-time protection slows down your PC, right? Now is the time to find out, whether real-time protection is slowing you down or not.
Step 1: First, go to settings, and then click on “Update and Security.”
Step 2: Second, turn off “real-time protection” and turn off “cloud-based protection.”
I have already turned off because I am using Avast antivirus program that takes cares of the real-time protection for me. Now, restart your PC and check if the problem is real-time or msmpeng.exe Antimalware service executable.
2. A Deep Scan on All Drives in Windows 10 PC
There is a virus called malware, and it is designed to cause problems for you and your computer. Number one, they are not easy to trace by MS Defender. Most of the users don’t know that MS Defender is not perfect and sometimes malware can slip from the eye of Microsoft antivirus system. Malware purpose is to make your life harder, and there is a malware called “Chromium browser” that increases RAM usage or memory usage to slow your PC down for no reason.
Go to safe mode and use another antivirus system from your Windows 10 PC.
In my case, I am using Avast Internet Security, and you can try the free version as well because it is a very good free antivirus system in the market.
Let me tell you that Avast free version is not good at malware detection, but Malwarebytes detects and cleans malware. But, Malwarebytes can’t detect adware, virus, and Trojans, so we need Avast that can detect and cleans it.
3. Turn Off Windows Defender
Many people in the world have installed the latest edition of the Windows 10 on their older machines. The interesting point of the Windows 10 is that the minimum requirement mentioned by the Microsoft does not apply to all computers in the world. Your computer hardware may not be compatible with the latest edition of Windows 10.
Note: Keep the “limited periodic scanning on” because once in a week scanning won’t hurt your computer.
I recommend you to get rid of the Windows Defender and opt for the Avast free antivirus and Malwarebytes free version because it does not slow down your PC that much and Malwarebytes works smoothly.
WD consumes a lot of RAM, and Processor speed and your computer may not handle it smoothly, so I recommend you to turn it off and opt for other options that I have mentioned.
So what’s next?
Avast Free Antivirus: The company that developed Avast is a billion dollar company because they managed to provide a free version to every single computer user in the world. It might not come as a surprise that Avast free version is better than many premium versions, yes, it is true.
Malwarebytes: I have installed Malwarebytes because Avast (any version) is not good at detecting malware, I have installed Malwarebytes because it is a perfect replacement for the Avast CON.
Avast might slow down your computer a little, but it won’t impact your computer performance more than 10% -15%. I have also tested Malwarebytes but no sign of slowing down, so I think, you don’t have to worry about Malwarebytes slowing down your PC.
Antimalware service executable should fix the issue once and for all.
4. Process Lasso
A few months back when my computer faces high CPU and Memory usage, then I started to look for a solution, and I came across Process Lasso that I use every day.
What is Process Lasso?
If you want to solve antimalware service executable high disk usage and memory usage, then you can use the most advanced program that helps you to keep your computer cool down, so it can perform at its best. I have not seen any optimization program work this good in my life because it works like a charm.
The Process Lasso did not pay us to add it, and we are using it on our Windows for a long time, and I can tell you that it works like a charm.
How does it work?
1: It has an algorithm that enables to monitor background running applications.
2: The Process Lasso analyze real-time when a program is trying to utilize processor and RAM more than it should on a basic level.
3: The Process Lasso use Microsoft Windows default feature called “Program Priority” that decides if the program is important for Windows to function or not.
There are low, medium, and high to determine the Microsoft services and regular software.
4: The Process Lasso has created an algorithm, and they named it “normal” that sets every time a Browsers, Games, Softwares, and more trying to utilize the CPU more than they are allowed to do it.
5: The Process Lasso keeps “normal” mode all time to balance the CPU usage.
It keeps my Windows 10 CPU performance optimal, and it does not let any program to slow down my CPU.
- It has an industrial look, and it looks way too advanced, but it isn’t. Install it and let the default settings do the job for you and you don’t need to edit anything.
- You have to do nothing and let it run in the background because it will keep your CPU to the optimal stage on default settings.
- It will improve your computer speed, and you won’t have “not responding” issues anymore.
Now, does this solve the problem of antimalware service executable Windows 10? Maybe or maybe not because there are a variety of problems when it comes to antimalware service executable high disk usage.
5. Change Windows Defender’s Schedule
In the second reason, I have mentioned that the Windows Defender might be scanning every file on your system back-to-back without a break and it can slow your PC down.
Well, we are going to fix it because scanning is something that should happen once in a day or once a week. But, it should not start scan every file on the computer every time you turn on your PC.
We are going to use the Microsoft OS inbuilt feature “task scheduler” that puts a lets your control the Microsoft antivirus the way you like it.
Step 1: Type “task scheduler” in the search bar or Cortana bar, and click on the first result.
Step 2: Click on “task scheduler library” > Microsoft > Windows folder, then you have to scroll down until you find Windows Defender folder.
Step 3: Scroll down to the bottom till you find WD folder in the list and click on it to open it.
Step 4: Now, you have to click on “Windows Defender Schedule Scan” and wait for a few seconds for it to open.
Step 5: Now, you have to deselect “run with highest privileges.”
Step 6: Now, click on “conditions” on the top menu and you have to deselect (2) the first four options pointed out in the snapshot and click on “OK” to complete the process.
You are done, and WD will only run once in a while and your computer saved from the antimalware service executable high disk usage.
You can turn off the msmpeng.exe antimalware service executable, but make sure you have installed Avast free antivirus and Malwarebytes to keep your computer safe from all threats. You can also try the Process Lasso because it helps your computer to run at an optimal level.
