Many Windows users have reported a high amount of memory usage due to the ‘Antimalware Service Executable’ program in Task Manager. However, contrary to popular belief, the program is not an undiagnosed virus or malware software. The Antimalware Service Executable is an official program specifically designed to help protect your computer system’s data, prevent potential viruses, malware attacks and other prospective vulnerabilities. 

Antimalware Service Executable utilizes a large amount of storage and system resources as it is tasked with continuously running in the background with uninterrupted malware scanning, installation of runtime software and monitoring computer files for liabilities. 

The ‘Antimalware Service Executable’ process is notorious for utilizing a comparatively large amount of system resources and memory and can hence affect the overall functionality of your Windows system. Therefore, the following article is a comprehensive and holistic step-by-step guide on how to reduce the high memory usage of the ‘Antimalware Service Executable’ program.

Solutions For Excessive Antimalware Service Executable High Memory Usage:

Method 1- Adjust Windows Defender Scheduling Options:

Windows Defender automatically schedules full-time Antimalware Service Executable scans. Therefore, you can reduce the strain of full-time malware scanning on your computer’s central processing unit (C.P.U.) by adjusting Windows Defender’s scheduling options to take place at particular timings with periodic intervals. 

Step 1: Open Task Scheduler

To run the program, open the Start menu, type “task scheduler,” and then select the first on-screen result.

Step 2: Open Windows Defender

Double-click the ‘Task Scheduler Library’ option in the left navigation pane. Navigate these folders further and proceed to the following path: Library/Microsoft/Windows/Windows Defender.

Step 3: Windows Defender Scheduled Scan

After opening the Windows Defender folder, double-click ‘Windows Defender Scheduled Scan’ in the central window.

Step 4: Halt Computer System Scans

Uncheck all the checkboxes and then click ‘OK; on the Conditions tab. This will halt any planned computer system scans.

Step 5: Windows Defender Scheduled Scan

It is necessary to schedule some periodic scans to safeguard your computer and files. However, scans can be performed in a way that minimizes the overall impact on your computer system’s performance. Therefore, double-click the ‘Windows Defender Scheduled Scan’ option, scroll to the ‘Triggers’ tab, and then select ‘New.’

Step 6: Custom System Scanning Schedule

Develop a custom, personalized system scanning schedule that meets your particular requirements and usage settings that find a middle ground between encryption and system performance. Weekly scans are recommended during periods when you are unlikely to notice the increment in CPU consumption.

Step 7: Remaining Functions

Repeat the entire above-mentioned procedure for the remaining three functions (Windows Defender Cache Maintenance, Windows Defender Cleanup, and Windows Defender Verification) under the Library/Microsoft/Windows/Windows Defender folder.

Method 2- Disable Windows Defender Service

If the system memory usage is extreme, disabling the Windows Defender Service overall will help mitigate the issue. However, note that doing so exposes your computer system to a wide variety of cyberattacks. Therefore, you must install an appropriate anti-malware program on your computer before deactivating Windows Defender.

Step 1: Run Dialog Box

To launch the Run Dialog Box, press ‘Windows Key + R.’

Step 2: Open Registry Editor

To open the Registry Editor, type ‘Regedit’ in the Run Dialog Box and select ‘OK’.

Step 3: Windows Defender

Double-click the folders in the left navigation pane to proceed to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender. 

Step 4: Disable Anti Spyware

If you see a registry entry entitled ‘DisableAntiSpyware,’ double-click it and set the value data to 1.

Method 3- Exclude Antimalware Service Executable From Windows Defender 

Windows Defender examines and analyses every file on your computer, including itself, throughout its scans. This can result in a system lag. To avoid this, just instruct the Windows Defender program to exclude itself while conducting a routine system scan.

Step 1: Launch Windows Task Manager

To launch the Windows Task Manager, select ‘Ctrl + Shift + Esc.’

Step 2: Open File Location

Browse for ‘Antimalware Service Executable’ in the list of available processes. Select ‘Open File Location’ from the dialog box after you right-click on the process.

Step 3: Antimalware Service Executable

The entire route of the ‘Antimalware Service Executable process will be shown in the address bar. Copy the whole path by clicking on the address bar.

Step 4: Launch Windows Defender Security Center

To launch the Windows Defender Security Center, open the ‘Start’ menu, enter “windows defender,” and then select the first result.

Step 5: Virus And Threat Protection

Select ‘Virus and threat protection’, then ‘Virus’ and then ”threat protection settings.’

Method 4- Investigate Potential Malware Infections

It’s feasible that your computer system has fallen prey to a malware attack, which is causing Windows Defender to slow down your system. In this scenario, use any independent on-demand AV scanners to conduct a thorough and comprehensive system scan. To repair your system thoroughly, you need to run Windows Defender Offline Scan at boot time or utilize bootable AntiVirus Rescue Media.
