Exploring the Issue of Microsoft Defender Antivirus Scans Being Stopped Before Completion

Microsoft Defender Antivirus is a powerful security tool that helps protect your computer from malware, viruses, and other threats. However, in some instances, you may encounter a situation where the antivirus scan is stopped before completion. This can be frustrating and leave your computer vulnerable to potential threats.

Possible Causes of the Issue

There can be various reasons why your Microsoft Defender Antivirus scan is stopping before completion. Some of the common causes include:

• Conflicts with other security software: If you have multiple antivirus programs or security software running simultaneously, they can interfere with each other and cause the scan to stop.
• Corrupted or outdated system files: If your operating system files are corrupted or outdated, it can disrupt the scanning process and lead to premature termination.
• Insufficient system resources: Running resource-intensive applications or multiple programs simultaneously can strain your computer's resources, causing the antivirus scan to halt.
• Malware or virus infection: In some cases, a malware or virus infection may have already compromised your system, leading to the interruption of the antivirus scan.

To resolve this issue, it is important to identify the underlying cause and take appropriate measures to ensure a complete and successful antivirus scan.

Steps to Resolve the Issue

To address the problem of Microsoft Defender Antivirus scans being stopped before completion, follow these steps:

Step 1: Disable Conflicting Security Software

If you have multiple antivirus programs or security software installed on your computer, they can conflict with Microsoft Defender Antivirus. Disable or uninstall any other security software and only keep Defender running. To do this:

• Open the Control Panel on your computer.
• Click on "Programs" or "Programs and Features."
• Locate the conflicting security software.
• Select the program and click on "Uninstall".

Once you have disabled or uninstalled the conflicting software, restart your computer and check if the antivirus scan completes without interruption.

Step 2: Update Your Operating System

Outdated or corrupted system files can disrupt the scanning process of Microsoft Defender Antivirus. To update your operating system:

• Click on the Windows Start button and select "Settings."
• Go to "Update & Security."

• Select "Check for updates."

If any updates are available, install them and restart your computer. This will ensure that your system files are up to date, resolving any potential conflicts during the antivirus scan.

Step 3: Close Resource-Intensive Applications

If your computer's system resources are overwhelmed by resource-intensive applications or multiple programs running simultaneously, it can cause the antivirus scan to stop. To resolve this:

• Close any unnecessary applications or programs running in the background.
• Ensure that your computer has sufficient memory and processing power to handle the scanning process.

Step 4: Run a Full System Scan in Safe Mode

If the above steps do not resolve the issue, you can try running a full system scan in Safe Mode. Safe Mode starts your computer with basic functions and minimal processes, reducing the likelihood of conflicts or interruptions. To run a full system scan in Safe Mode:

• Restart your computer and press the F8 key repeatedly before the Windows logo appears.
• Select "Safe Mode" from the boot menu.
• Once in Safe Mode, open Microsoft Defender Antivirus and initiate a full system scan.
