How to Stop Antimalware Service Executable from Slowing Down Your Windows 10 Computer post thumbnail

Many Windows 10 users are complaining that their computer is running slow. When they check their system Task Manager to see what is the problem, they see a process called Antimalware Service Executable eating up both their PC memory and CPU.

The Concept of Malware

Everywhere we look, antivirus programs are dominating the digital security market. But the fact is, virus is not the only source of threat to your computer.

There are several other types of programs that can cause a considerable damage (such as Trojan, Ransomware, Worm, Spyware, etc.).

All these other programs mentioned above and including virus are categorized as Malware.

What is Antimalware Service Executable?

Antimalware Service Executable is a process which Microsoft added to Windows Defender, with the purpose of protecting your computer from all other forms of security threats that are not virus.

In other words, Antimalware Service Executable is not a stand-alone program, neither is it a virus in your computer. it is there because Microsoft is using it to protect your computer as part of the Windows Defender initiative.

How to end the Antimalware Service Executable Process

There are basically 3 ways to stop the Antimalware Service Executable process, these are:

  1. Use a third-party antivirus.
  2. Disable Windows Defender Real-time protection
  3. Disable Windows Defender.

Using a Third-party Antivirus

As I have mentioned above, Antimalware Service Executable is part of the processes of Windows Defender.

Windows Defender is preinstalled into your computer as soon as you installed Windows 10. It is Windows free default antivirus software.

However, Windows Defender will automatically disable itself when it notices that you have installed another antivirus into your computer.

So, after you have installed a third-party antivirus in your computer and the Windows Defender has automatically disable itself, the Antimalware Service Executable with stop running automatically. This is because, the host program which is Windows Defender have been disabled.

Disable Windows Defender Real-time Protection

Another way you can stop the Antimalware Service Executable process from eating up your computer’s memory and CPU is by turning off Windows Defender real-time protection feature.

With this option, you do not need to buy and install another antivirus program if you do not want to. And also, you do not need to disable the Windows Defender altogether.

Once you have disabled the real-time protection feature, Windows Defender will stop all the processes it is using to protect your computer in real-time. And because Antimalware Service Executable is among these processes, it too will be stopped.

However, anytime you initiate a scan with Windows Defender, the Antimalware Service Executable process will also be among the processes Windows Defender will run on your computer.

But when the scan is complete, all processes including Antimalware Service Executable will be stopped.

In other words, with this option, you are telling Windows Defender to run the Antimalware Service Executable process only when you need it and not every time. This to me is the best option.

Disable Windows Defender.

As I pointed out in the first option above, when Windows Defender is disable, the Antimalware Service Executable process also stop working.

So if you do not like Windows Defender, you can just disable it. Here is the guide on how to disable Windows Defender.

Well, this option is not what I will encourage if you do not have another antivirus program installed in your computer. This is because without any antivirus in your computer, you are opening it up to all sort of malware.

So, think carefully about this option before you decide to act in harmony with this option.
