If you have seen an Antimalware Service Executable program in Task Manager, don’t worry. It is not a third-party service or a virus that mimics an antivirus. This is an official Windows program that protects your Windows PC. Here we answer all your questions about the question – What is Antimalware Service Executable (msmpeng.exe) and why does it show high CPU, disk or memory usage under Windows 10? Is it a virus? Should I disable it? All the answers to these questions can be found in this article.
What is Antimalware Service Executable
Windows 10 and Windows Defender, now integrated into the operating system kernel and prepared as Windows Defender Antivirus System, has come a long way. Like many other programs that need to run continuously in the background, WDAS runs in the background as Antimalware Service Executable (MsMpEng.exe).
If for any reason you’ve seen it in the Memory Consuming Task Manager, and CPU more than ever before, don’t worry. The antivirus program must often run in the background with scheduled scanning, scan files for malware, install the software at runtime, and continuously monitor files for changes.
The best way to check is to right-click the program name in the Task Manager and open the file. You will notice that it is available at C:ProgramDataMicrosoftWindows DefenderPlatform4.16.17656.18052-0. You can also run the Defender program manually to perform a scan, which increases CPU and memory usage.
Antimalware Service Executable shows high CPU/memory usage
If you are wondering, this is not quite right. I saw this program in the background and did nothing. Sometimes I’ve seen that it consumes 30% of CPU usage. If you have seen that it takes a large amount of CPU, there is a chance that it scans your files in the background. This is to ensure that there are no viruses or malware.
You will notice that this type of surge occurs during certain events. If your PC starts, the software is installed when you download the file from the Internet or check your Outlook emails with attachments.
The best thing about this Antimalware Service Executable or Windows Defender is that it performs background scans only when your PC is idle. This ensures that your PC is not slow when you are working, and running inactive scans has the advantage of consuming more CPU resources.
If you disable Antimalware Service Executable
We do not recommend all. The main reason for our support is that it works with third-party antivirus solutions. This gives you reason enough not to disable Windows Defender. Windows Defender automatically disables it when you install a third-party antivirus program.
There are many other reasons. Windows Defender is the latest protection you have when it comes to ransom software that can lock your files. Microsoft has implemented this feature with OneDrive to ensure that your files are secure and recoverable.
However, if you think it consumes too many resources, you can disable real-time protection. Go to Settings > Update & Security > Virus and Threat Protection > Virus and Threat Protection Settings and turn off real-time protection. It is automatically activated if no antivirus software is installed on your PC.
As I said, Windows Defender works with other antivirus solutions. Even if it turns itself off, it will scan your PC from time to time. It will discover what risks your primary antivirus solution may have neglected.
The main reason for writing this message is the recommendation to completely disable these services in many forums. It is not wise to act on my experience.
