Windows Security vs. Microsoft Defender Antivirus
Before you dive into this guide, you need to understand the difference between "Microsoft Defender Antivirus" and "Windows Security."
Windows Security is the application that provides a unified experience to view status and manages security features, such as antivirus, firewall, performance, and other security features.
On the other hand, Microsoft Defender Antivirus is the default anti-malware engine that offers real-time protection against may forms of malware, including viruses, spyware, ransomware, and hackers.
Installing a third-party antivirus will disable the Microsoft Defender Antivirus automatically, but it'll not affect the functionality of Windows Security. In the same way, disabling Microsoft Defender Antivirus or Microsoft Defender Firewall won't disable Windows Security.
How to navigate Windows Security
Windows Security is a straightforward application. You can open it from the Start menu or double-clicking the shield icon from the notification area in the taskbar.
In the Home page, you can view the security status of the different protection features available by default on Windows 10. You can also see alerts of any action that needs to be taken to keep your computer secure.
The shield icon in the notification area can also alert you when an action needs to be taken. If there is more than one alert, only the most severe warning will appear. Also, if you right-click the app icon, you'll have access to actions, such as quick scan, download updates, adjust notifications, and access the dashboard.
Windows Security includes seven areas of protection that you can manage and monitor:
- Virus & threat protection – houses the Microsoft Defender Antivirus settings. It allows you to monitor the malware protection, scan the device for threats, launch an offline scan, and set up the advanced anti-ransomware feature.
- Account protection – allows you to see how to protect your identity on Windows 10.
- Firewall & network protection – lets you monitor network connections, and you can configure various Microsoft Defender Firewall settings.
- App & browser control – helps you protect your device and data from malicious code hidden on apps, files, and websites.
- Device security – provides hardware-level security features, such as Core isolation and Security processor, to protect your computer from certain attacks.
- Device performance & health – display the health and performance report of your computer.
- Family options – offers easy access to manage your devices and kids' online experience using a Microsoft account.
How to scan computer for malware using Microsoft Defender Antivirus
Windows 10 automatically updates and scans the device for malware regularly, but you can perform different scans manually.
Quick virus scan
A quick scan happens fast, and it only scans the parts of the system where malware is known to hide.
To start a virus scan with Microsoft Defender, use these steps:
Once you complete the steps, under the Current threats section, you'll see any detected threats, as well as the time it took to complete the scan and the number of scanned files.
If you suspect that a virus is still on your computer, you should try to perform a full scan.
Full virus scan
A full virus scan takes longer, but it makes sure to check every file, folder, and application.
To start a full virus scan with Microsoft Defender, use these steps:
- Open Windows Security.
- Click on Virus & threat protection.
-
Under the "Current threats" section, click the Scan options link.

Select the Full scan option.
- Click the Scan now button.
After you complete the steps, you can continue using the device, while the antivirus will perform a full scan to detect any potential malware.

Sometimes if you're dealing with a tough virus or another type of malware, the antivirus may not be able to remove it while Windows 10 is running. If this is the case, you can use Microsoft Defender to perform an offline scan. When using this feature, the computer will restart automatically in the recovery environment, and it'll perform a full scan before Windows 10 starts.
