• Type "Windows Security" in the search bar.
  

  As you type, Windows will start searching for matching results.

• Click on the "Windows Security" app.
  

  The Windows Security app should appear at the top of the search results.

  This tab contains settings related to antivirus protection, including Microsoft Defender Antivirus.

Once you have opened the Virus & threat protection tab, you can proceed with the steps to deactivate Microsoft Defender Antivirus.

Select Virus & threat protection.

The Virus & threat protection tab in Windows Security provides a centralized view of the antivirus and threat protection settings for your system. This tab includes options for managing Microsoft Defender Antivirus, scanning for threats, and configuring other security settings.

• Real-time protection:

Disabling real-time protection will prevent Microsoft Defender Antivirus from scanning files and programs as they are accessed, which can make your system more vulnerable to threats.

• Cloud-delivered protection:
  

  This setting controls whether Microsoft Defender Antivirus uses cloud-based threat intelligence to identify and protect against the latest threats. Disabling cloud-delivered protection will limit Microsoft Defender Antivirus's ability to detect and respond to new and emerging threats.

• Automatic sample submission:
  

  This setting controls whether Microsoft Defender Antivirus automatically submits suspicious files and samples to Microsoft for analysis. Disabling automatic sample submission may reduce the effectiveness of Microsoft Defender Antivirus in detecting and protecting against new threats.

• Tamper Protection:
  

  This setting prevents unauthorized changes to Microsoft Defender Antivirus settings and components. Disabling Tamper Protection can make your system more vulnerable to attacks that attempt to disable or bypass antivirus protection.

To deactivate Microsoft Defender Antivirus, you need to disable the Real-time protection setting.

Click Manage settings.

The Manage settings button in the Virus & threat protection tab provides access to additional antivirus and threat protection settings. These settings allow you to fine-tune how Microsoft Defender Antivirus operates on your system.

• Virus & threat protection settings:
  

  This section contains settings related to the behavior of Microsoft Defender Antivirus, such as how it handles detected threats, scans files and programs, and updates its definitions.

  This section contains advanced settings for Microsoft Defender Antivirus, such as the ability to configure custom scan options and manage threat detection policies.

• Windows Security notifications:
  

  This section allows you to configure how Windows Security notifies you about detected threats and other security events.

To deactivate Microsoft Defender Antivirus, you need to click on the Manage settings button and then toggle the switch under Real-time protection to Off.

Toggle the switch under Real-time protection to Off.

The Real-time protection setting in Windows Security controls whether Microsoft Defender Antivirus is actively monitoring your system for threats and taking action to protect it. By default, this setting is turned on, which means that Microsoft Defender Antivirus is constantly scanning files and programs as they are accessed and taking action to block or remove any detected threats.

To deactivate Microsoft Defender Antivirus, you need to toggle the switch under Real-time protection to Off. This will disable real-time scanning and protection, which means that Microsoft Defender Antivirus will no longer be able to automatically detect and block threats.

It is important to note that disabling real-time protection can make your system more vulnerable to malware and other threats. Therefore, it is generally recommended to only disable real-time protection temporarily, such as when you are installing or troubleshooting other security software.

Once you have finished the task that requires you to disable real-time protection, you should re-enable it as soon as possible to ensure that your system is fully protected.

Confirm the deactivation.

Once you have toggled the switch under Real-time protection to Off, Windows Security will prompt you to confirm the deactivation. This is a security measure to prevent accidental or unauthorized deactivation of antivirus protection.

• Click on the "Yes" button.
  

  This will confirm the deactivation of Microsoft Defender Antivirus.

• Wait for the deactivation process to complete.
  

  Depending on your system configuration, this process may take a few seconds or minutes.

• Check the status of Real-time protection.
  

  Once the deactivation process is complete, the switch under Real-time protection should be in the Off position.

• Restart your system (optional).
  

  Restarting your system can help to ensure that the changes take effect and that Microsoft Defender Antivirus is fully deactivated.

After you have confirmed the deactivation of Microsoft Defender Antivirus, you can proceed with the task that requires you to disable real-time protection.

Re-enable protection when finished.

Once you have finished the task that required you to disable real-time protection, it is important to re-enable it as soon as possible to ensure that your system is fully protected.

• Open Windows Security.
  

  You can do this by clicking on the Start menu and typing "Windows Security" in the search bar.

• Select Virus & threat protection.
  

  This tab contains settings related to antivirus protection, including Microsoft Defender Antivirus.

• Click on the Manage settings button.
  

  This button provides access to additional antivirus and threat protection settings.

• Toggle the switch under Real-time protection to On.
  

  This will re-enable real-time scanning and protection, and Microsoft Defender Antivirus will once again be able to automatically detect and block threats.

After you have re-enabled real-time protection, Microsoft Defender Antivirus will begin scanning your system for threats. It is important to keep Microsoft Defender Antivirus up to date with the latest definitions and updates to ensure that it can effectively protect your system from the latest threats.

Use third-party antivirus (optional).

If you are not satisfied with Microsoft Defender Antivirus or if you want to use a different antivirus solution, you can install a third-party antivirus program. There are many reputable third-party antivirus programs available, such as Norton, Bitdefender, and Kaspersky. These programs offer a variety of features and protection options, so you can choose the one that best meets your needs.

When choosing a third-party antivirus program, it is important to do your research and read reviews from other users. You should also make sure that the program is compatible with your version of Windows and that it will not conflict with any other software that you are using.

Once you have installed a third-party antivirus program, you can disable Microsoft Defender Antivirus. This will prevent Microsoft Defender Antivirus from running alongside the third-party program, which can help to avoid conflicts and performance issues.

It is important to note that using a third-party antivirus program does not guarantee complete protection against all threats. It is still important to practice safe computing habits, such as being cautious about opening email attachments and downloading files from unknown sources.
