Windows 11 24H2 - Memory Usage Secure System and MS AV

Question

The latest Windows 11 now appears to be completely virtualized. The MsMpEng and new Secure System services seem to be taking up over 1GB of memory and other resources than what was previously used. And the MpDefenderCoreService appears to be sending information to Microsoft with no option to stop it. I have tried a 100 ways to disable this. And MSINFO32 still says VBS is running. At this point I would be grateful for a solution that works to disable VBS.

Hi Stan,

Thanks for your post. I understand your frustration. The Antimalware Service Executable is a part of Windows Defender, and it's designed to run continuously in the background to protect your computer from malware. However, it should not be using as much memory as you've described.

Here are a few things you can try:

1. Change Windows Defender's Schedule:

• Open Task Scheduler.
• Go to Library/Microsoft/Windows/Windows Defender.
• Disable all the tasks you find there.
• This will stop Windows Defender from performing scans without your permission.

2. Add Antimalware Service Executable to Windows Defender's Exclusion List:

• Open Windows Security settings.
• Go to Virus & Threat Protection settings.
• Exclusions, add or remove and add Antimalware Service Executable (MsMpEng.exe) to the list.
• This will stop Windows Defender from scanning its own processes.

3. Check for Malware:

• Your computer might be infected with malware that's causing the Antimalware Service Executable to use more resources than it should.
• Use a reliable third-party antivirus software to scan your computer.

4. Install the Latest Updates:Go to Settings, Update & Security, and click on Check for updates.

Remember that completely disabling your antivirus should be your last resort, as it can leave your PC vulnerable to threats. If none of the above solutions work, you might want to consider using a different antivirus program.

If you have more questions or need further assistance, feel free to ask.

Best Regards,
