The Antimalware service executable is part of the Windows Defender

The main objective of this application is to keep your computer virus-free. Because it’s a built-in product, many users do not trust it and want to switch it off. There are reports of Windows Defender deactivating an out-of-date antivirus program and picking up the torch of protecting your computer. Even though there is never a reason not to use your antivirus, you can never bee too careful. So, if you already have an antivirus installed, pair it up with Windows Defender. You can also invest in a tool that will integrate seamlessly with both – Auslogics Anti-Malware.

This means that when and if you get an antivirus program instead of the one that didn’t perform well, the Windows Defender will stop running on its own provided that your antivirus has already begun the scan. You can check if it’s running by following these guidelines:

  • Step 1. Enter the Windows Defender Security Center in your Start Menu.
  • Step 2. Navigate to the Virus and threat protection.
  • Step 3. Check if the message “You’re using other antivirus providers” appears. This effectively means that you have disabled the Windows Defender.
