How to Run Windows Defender Scan on Windows 11
As digital threats become increasingly sophisticated, computer security has never been more vital. Windows 11, Microsoft’s latest operating system, includes Windows Defender, a powerful built-in antivirus and security solution. This guide aims to provide a comprehensive understanding of how to run a Windows Defender scan on Windows 11, ensuring your device remains secure and your personal data protected.
Before diving into the scanning process, it’s essential to have a foundational understanding of Windows Defender. Formerly known as Windows Defender Antivirus, this program has evolved into a more robust security suite, integrating not only antivirus protection but also features such as firewall and network protection, app and browser control, device performance, and health optimization.
With Windows Defender, users can schedule scans, run on-demand scans, and access advanced tools that enhance their operating system’s security. It operates in real-time to detect threats and also runs periodic scans to ensure your computer is safeguarded against malware, potentially unwanted programs (PUPs), and other forms of cyber attacks.
To begin, we need to access Windows Defender on your Windows 11 system. Here are the steps to do so:
Using the Start Menu
:
Click on the Start Menu (the Windows icon) in the taskbar at the bottom of your screen. From there, you can type “Windows Security” in the search bar.
Using Settings
:
Alternatively, you can access it through the Settings. Click on the Start Menu, select the gear icon (Settings), then navigate to
Privacy & Security
, followed by
Windows Security
.
Once you’ve opened Windows Security, you’ll see several options like Virus & threat protection, Account protection, Firewall & network protection, and more.
Windows Defender offers a variety of scanning options to tailor the protection according to your needs:
Quick Scan
: This is the default scan type that checks the most common areas where malware is found. It usually takes a short amount of time—typically around 15-30 minutes.
Full Scan
: This thorough scan checks all files and running programs on your computer. It can take significantly longer, depending on the amount of data you have, but it offers a more comprehensive security check.
Custom Scan
: This allows you to specify particular files or folders you want Windows Defender to scan. It’s particularly useful for targeting areas you suspect may be compromised.
Offline Scan
: This scan restarts your PC and examines files before Windows loads, allowing detection of even tricky malware that hides during regular operations. It is particularly effective against rootkits.
Once the scan is complete, Windows Defender will present any detected threats and offer actions such as quarantine or removal.
Prepare for a wait, as this scan can take from several minutes to a few hours, depending on your system’s performance and the amount of data.
After running any type of scan, reviewing the results is essential.
To ensure maximum protection, it’s crucial to keep Windows Defender definitions up to date.
Windows Defender is designed to update automatically, but it’s wise to manually check sometimes, particularly after a major update to Windows 11 or if you suspect you’ve been targeted.
Windows Defender offers additional protective measures that can be configured for enhanced security:
Real-time Protection
: Ensure that real-time protection is switched on. It scans files when they’re accessed, providing immediate feedback on potential threats.
Cloud-Delivered Protection
: This feature allows Windows Defender to use cloud intelligence to identify threats, delivering new definition updates in real-time.
Automatic Sample Submission
: By enabling this, if Windows Defender detects a questionable file, it can automatically send a sample to Microsoft for analysis.
Controlled Folder Access
: This feature protects your files from unauthorized access by providing a shield around specific folders.
Ransomware Protection
: Activate this feature for additional layers of security against ransomware attacks, ensuring your files remain protected.
Firewall & Network Protection
: It’s essential to configure your firewall settings to block unauthorized access to your computer while online.
Routine scans can catch threats that may arise between your manual checks. To schedule scans:
By scheduling regular scans, you minimize the chances of malware infections that could remain undetected.
Even though Windows Defender is robust, problems can occasionally arise. Here are some common issues and solutions:
-
Windows Defender Won’t Open
: Restart your computer and try accessing it again. If the problem persists, running the Windows Troubleshooter can help diagnose issues with the application. -
Scan is Taking Too Long
: High system load, background processes, or large volumes of data can affect scan time. Ensure you close unnecessary applications before scanning. -
Windows Defender is Disabled
: If you have another antivirus installed, it may disable Windows Defender to avoid conflicts. Consider uninstalling third-party security software if you prefer to use Windows Defender.
