With an increase in the spread of vulnerable programs such as viruses and malwares, Microsoft has increased windows security with it’s all-new Microsoft Defender Antivirus. From Windows 10 version 2004, Windows Defender has been renamed to Microsoft Defender Antivirus, which is enabled by default and actively protects you from all the latest security threats. The updates are automatically downloaded, and Microsoft continually updates the virus definition to keep your device safe.

Microsoft defines the Defender Antivirus as the next-generation protection component Microsoft Defender Advanced Threat Protection(MDATP) provides below features,

  • Real-time antivirus protection
  • Built-in cloud protection while surfing the web, downloading email attachments or accessing OneDrive 
  • Block at first sight (BAFS) protection

Without real-time protection, your operating system would be unsafe and hostile to work on as malicious programs spread quickly over email, USB flash drives, or browsing the internet. Malwares can affect your system without your knowledge and can steal potential information or even damage your disk drives. 

You can turn off the Windows Defender Antivirus temporarily. Windows automatically turn on the real-time protection if it’s disabled for a while. In this advanced Windows 10 tutorial, we will walk you through the steps to turn on or off the Windows Defender Antivirus permanently for all the users.

Note:

  • Systems with multiple users, make sure you are signed in as an administrator to enable or disable the antivirus.
  • If you are installing any third-party Antivirus programs, then they disable the Microsoft Defender Antivirus. In this case, you cannot enable it till you uninstall the third-party antivirus program.
  • With Windows 10 build 18305 or higher version, you need to disable Tamper protection to disable Microsoft Defender Antivirus.
