Windows Security Virus and Threat Protection Won't Restart: Troubleshooting Guide

If you are encountering issues with the Windows Security Virus and Threat Protection feature not restarting on your computer, it can be frustrating and concerning. The Virus and Threat Protection is a vital component of Windows Security that helps protect your system from malware and other online threats. In this article, we will explore common causes for this issue and provide troubleshooting steps to resolve it.

1. Outdated Windows Defender Antivirus Definitions

One of the common reasons why the Virus and Threat Protection won't restart is due to outdated Windows Defender Antivirus definitions. Antivirus definitions are files that contain information about known malware and other threats. If your definitions are not updated, Windows Security may not function properly.

To resolve this issue, you can manually update the antivirus definitions by following these steps:

• Open Windows Security by clicking on the Start menu and typing "Windows Security".
• Click on "Virus & Threat Protection".
• Under "Virus & Threat Protection updates", click on "Check for updates".
• Wait for Windows Security to download and install the latest updates.
• Restart your computer and check if the Virus and Threat Protection feature is working.

Alternative Method: Using Windows PowerShell

If the manual update process doesn't work, you can try updating the definitions using Windows PowerShell:

• Open Windows PowerShell as Administrator by right-clicking on the Start menu and selecting "Windows PowerShell (Admin)".
• Type the command "Update-MpSignature" and press Enter.
• Wait for the process to complete.
• Restart your computer and check if the Virus and Threat Protection feature is working.

2. Conflict with Third-Party Antivirus Software

If you have third-party antivirus software installed on your computer, it might be conflicting with Windows Security and preventing the Virus and Threat Protection from restarting. Antivirus programs often have their own security features that can interfere with Windows Security.

To check if this is the issue, you can temporarily disable or uninstall the third-party antivirus software and see if it resolves the problem. Keep in mind that removing or disabling antivirus software can leave your computer vulnerable, so it's important to re-enable or install an alternative antivirus solution promptly.

If disabling or removing the third-party antivirus software resolves the issue, consider reaching out to the software vendor for support or switching to a different antivirus solution that is compatible with Windows Security.

Windows Security Alerts and Actions

Windows Security alerts and actions can also interfere with the functioning of the Virus and Threat Protection feature. These alerts and actions may arise due to other system settings or configurations. To check if this is the case:

• Open Windows Security.
• Click on "Virus & Threat Protection".
• Under "Virus & Threat Protection settings", click on "Manage settings".
• Scroll down to the "Notifications" section.
• Disable the "Receive Windows Security messages" option.
• Restart your computer and see if the Virus and Threat Protection feature restarts successfully.

3. Corrupted Windows Security Files

In some cases, corrupted Windows Security files can cause the Virus and Threat Protection feature to malfunction. To fix this issue, you can use the Windows Security Troubleshooter, which is a built-in tool designed to identify and repair problems related to Windows Security.

Follow these steps to run the Windows Security Troubleshooter:

• Open the Settings app on your computer by pressing Windows + I.
• Click on "Update & Security".
• Go to the "Troubleshoot" tab.
• Scroll down and locate "Windows Security".
• Click on "Windows Security" and then on "Run the troubleshooter".
• Wait for the troubleshooter to complete the scanning and repairing process.
• Restart your computer and check if the Virus and Threat Protection feature is working.

Alternative Method: Resetting Windows Security

If the troubleshooter doesn't resolve the issue, you can try resetting Windows Security to its default settings. Here's how:

• Open Windows Security.
• Click on "Virus & Threat Protection".
• Under "Virus & Threat Protection settings", click on "Manage settings".
• Scroll down and click on "Restore settings to their default values".
• Follow the on-screen instructions to reset Windows Security.
• Restart your computer and check if the Virus and Threat Protection feature is working.

Windows Security Virus and Threat Protection Won't Restart: Second Dimension

In this section, we will explore another dimension related to the issue of Windows Security Virus and Threat Protection not restarting. We will provide additional troubleshooting steps to help you resolve the problem.

1. System File Corruption

System file corruption can also lead to the Virus and Threat Protection feature not restarting. Corrupted system files can cause various issues with the functioning of Windows Security. In such cases, running the System File Checker (SFC) tool can help identify and repair corrupt files.

To use the System File Checker tool, follow these steps:

• Open Windows PowerShell as Administrator by right-clicking on the Start menu and selecting "Windows PowerShell (Admin)".
• Type the command "sfc /scannow" and press Enter.
• Wait for the scanning and repairing process to complete.
• Restart your computer and check if the Virus and Threat Protection feature is working.

Alternative Method: DISM Tool

If the System File Checker tool does not resolve the issue, you can also try using the Deployment Image Servicing and Management (DISM) tool to repair the Windows image. DISM is another built-in tool that can help fix issues related to system image corruption.

• Open Windows PowerShell as Administrator.
• Type the command "DISM /Online /Cleanup-Image /RestoreHealth" and press Enter.
• Wait for the process to complete.
• Restart your computer and check if the Virus and Threat Protection feature is working.

2. Third-Party Firewall Interference

Just like third-party antivirus software, third-party firewalls can also interfere with the functioning of Windows Security and prevent the Virus and Threat Protection feature from restarting properly. Firewalls are designed to monitor and control network traffic, and they can sometimes conflict with the built-in security features of Windows.

To check if the third-party firewall is causing the issue, you can temporarily disable it or configure it to allow Windows Security full access to your system. Consult the documentation or support resources of your specific firewall software for instructions on how to disable or configure it correctly.

After disabling or configuring the third-party firewall, restart your computer and check if the Virus and Threat Protection feature is working as expected.

3. Windows Security Service Failure

In some cases, the underlying service responsible for the Virus and Threat Protection feature may fail to start or restart properly. To address this issue, you can try restarting the Windows Security service using the Services console.

Follow these steps to restart the Windows Security service:

• Press Windows + R to open the Run dialog box.
• Type "services.msc" and press Enter.
• In the Services console, scroll down and locate the "Windows Security" service.
• Right-click on the service and select "Restart".
• Wait for the service to restart.
• Restart your computer and check if the Virus and Threat Protection feature is working.

If the Windows Security service fails to start or restart, you may need to contact Microsoft support for further assistance.
