Often when you update your computers antimalware or antivirus, you get an issue with the antimalware occupying a huge percentage of the CPU memory/RAM, thereby slowing your computer down.
Antimalware Service Executable is a component of your Windows Defender application and it helps protect your Windows PC from malware, virus, and suspicious attacks. As an inbuilt feature of Window Defender it keeps your computer safe, by running in the background and scanning any threatening content or files that it intercepts on your computer, which you can get via email or by visiting risky sites.
While Antimalware Service Executable is highly frustrating and may cause you to end the process several times, you cannot do without it simply because you need to protect your computer and keep it functional. Let us show you how to overcome this challenge with some steps that we recommend. Firstly, the Window Defender is an application that constantly runs in the background, as long as you PC are on. Windows Defender, by default, runs with two options that are pre-selected – one is the ‘real-time’ protection and the second feature is the ‘deep scanning’ which constantly and continuously scans your computers files to fix threats it finds. Now, you first need to diagnose whether it is either of these two issues that are occupying your computer’s hard disk and memory. Let’s show you how to check that out.
Fixing your PC for slow down issues due to ‘Real-Time Protection’ feature
- Go to your computers ‘Settings’ and then to ‘Update and Security’
- Turn off the ‘Real-Time Protection’ feature
- Turn off the ‘Cloud based Protection’ feature
Once you have done the above changes, reboot your computer and check the Task Manager for the Antimalware Service Executable process or the msmpeng.exe file. See the CPU and memory occupancy and if you see that now the Antimalware Service Executable is not occupying so much of the CPU hard disk or the memory, then your problem stands fixed.
Fixing your PC for slow down issues due to ‘Deep Scanning’ feature
Once you have altered the real-time protection issue, you next need to check if the deep scanning is also slowing your PC down. So,
- Go to your computers ‘Settings’ and then to ‘Update and Security’
- Here, you will see a sub-setting ‘Limited Periodic Scanning’ – turn this feature ‘On’
- Select a frequency for deep scanning of your files – preferably a week.
Again, reboot your PC once you have done the above change and if you now find that the Antimalware Service Executable or the msmpeng.exe file not occupying high percentages of your CPU or memory, then you know that you have fixed the slow down issue you were facing with your PC.
While the above should help is fixing PC slowdown issues, you need to understand that your PC is going to be at risk with the real-time protection and deep scanning feature now turned to ‘periodic’ frequency instead of constantly. This essentially exposes your PC to threats from antivirus and malware. Let us guide you about how you can keep your PC protected as well as enjoy its optimal functioning. At all points in time, you definitely should consider a round-the-clock protection for your PC because you don’t know when you will face a threat – either by way a virus attack or a Trojan or malware.
