    anti malware service executable

    I did a complete scan on the PC through Windows defender (win 10) and I saw anti malware service executable in the task manager. It's the first time I do a complete scan. Question: Was this in the task
    manager before or I didnt notice it?. I read that it is wasting a lot of cpu usage. If I close it, my pc will be vulnerable to malwares?. Thanks in advance!

    Locked anti malware service executable by TrustedInstaller

    Hi.

    the anti malware service executable makes my computer very slow.

    I have tried to follow every step in the following guide (https://windowsreport.com/kill-antimalware-service-executable-windows-10/) to stop it but it doesnt work.

    my last resort was to try to manually delete Windows Defender folder, yet its protected by TrustedInstaller.
    And I could not take ownership.

    Any help would be welcome as my work is getting delayed due to this situation.

    yours Alon

    Anti-Malware service executable CPU usage

    One of the solutions that worked for me Using the Registry Fix anti-malware executable service

    1. To open the Run Dialog Box, press Windows Key + R.
    2. Type Regedit and click OK in the Run dialog box to open the Registry Editor.
    3. Double-click in the left navigation pane to browse the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender.
    4. If you encounter DisableAntiSpyware, double-click it to edit it and set its data value to 1.
    5. If you do not see a DisableAntiSpyware registry entry, right-click on Windows Defender and choose New > DWORD (32 bit) value.
    6. Then name this new registry entry as DisableAntiSpyware and set the value data to 1.
    Alternatively, follow this video guide:

    I would recommend to keep that service running as it will keep your computer safe and secure from any attacks.
