Windows Defender is Windows’ primary security tool. Sometimes, you might not have access to your GUI and must access Windows Defender directly from the Command Prompt. This article will provide you with the best ways to run a virus scan from CMD.

Can I locate the virus using Command Prompt?

The short answer is yes; you can determine if your system is infected with a virus directly from Command Prompt. Virtually, all actions you carry out in your GUI can be done using the command line e.g Resetting your IP Address, searching for files, changing DNS servers, etc.

Locating viruses and malware using Command Prompt isn’t as intuitive as when done on the GUI. However, with the right steps and guidance, you can achieve exact results on the terminal you usually get on the GUI. 

One thing to note about operating your antivirus tool from the command line is that scans generated from the terminal will only provide you with a report of the viruses found in the system; it won’t delete or quarantine them, unlike on the GUI.

After discovering the virus from the Command Prompt app, you must delete it manually.

How can I run a virus scan from CMD?

1. Press the Windows key + S, type in command prompt, right-click on the displayed result, and select Run as Administrator.
2. In the User Account Control window, select Yes.
3. In the CMD window, type in the following command to navigate to the Microsoft Antivirus Directory: cd C:\ProgramData\Microsoft\Windows Defender\Platform\4.18*
4. After navigating to the Windows Defender directory, type in the following to run a quick scan: MpCmdRun.exe -Scan -ScanType 1
5. If you want to run a full scan, type the following command and press Enter: MpCmdRun.exe -Scan -ScanType 2
6. If you need to stop the scan mid-way, press Ctrl + C to quit the scan.

Just like on the GUI app, you’ll see the progress report of the scan. Like on the Windows Defender app, running a quick scan should only take a few minutes, depending on the size of the files stored on your computer.

There are cases where you’d like to run a full virus scan. Running a full virus scan ensures that all sectors of your computers are fully scanned. Scans like this take up way much time but are more efficient.

How do I run a custom scan from CMD?

1. Click the Start button, type cmd, and select Run as administrator to open an elevated Command Prompt window.
2. Type in the following command and press Enter: MpCmdRun.exe -Scan -ScanType 3 -File PATH
3. Ensure you replace PATH with the path to the folder you want to scan. For example, if you want to scan your desktop for viruses, you’ll use the command: MpCmdRun.exe -Scan -ScanType 3 -File C:\Users\YOURNAME\Desktop
4. Ensure you change the YOURNAME to your username.

How do I run a Boot Sector scan

1. Windows key + S, type in command prompt, right-click on the displayed result, and select Run as Administrator.
2. Type in the following command and press Enter: MpCmdRun.exe -Scan -ScanType -BootSectorScan

Running this command from the command prompt will scan your PC’s boot sector and remove any suspicious files found in the system. Here is a detailed guide on how to fix a corrupt boot sector.

How do I restore quarantined files using Command Prompt?

1. While in the command prompt, type in the following to view the list of quarantined files: MpCmdRun.exe -Restore -ListAll
2. Then type the following command: MyApp.exe along with the name of the file you want to restore, and press Enter.

When Windows Defender detects malicious files, it quarantines them. Oftentimes, the antivirus might mistakenly quarantine legitimate files.

Running a virus scan from the command prompt is less intuitive than the GUI. However, when you’ve been completely locked out of your GUI due to malware, you must run Windows Defender directly from the Command Prompt app.

For this, you will need an elevated Command Prompt window. We have a guide on what to do if you can’t open Command Prompt as administrator.

With the steps outlined above, you can run any virus scan directly from CMD. For any other questions or potential solutions, let us know in the comments section below.

The Windows operating system has a built-in anti-malware called the Microsoft Defender Antivirus which is always running to protect the user from potential attacks such as viruses, spyware, rootkits, and ransomware. This defender responds to the attacks by taking action immediately rather than responding to them after your computer has been infected.

As much as the Microsoft Defender is always running in the background to protect from attacks, one should run a full virus scan occasionally to ensure that nothing suspicious may have escaped the defender and infected your windows system. You can perform these scans when Windows is running slow, or you suspect the system is infected.

Let’s see how to do it.

Update the Windows defender using the command prompt

Running a Virus Scan from the CMD

To perform a scan on your system, you need to run the CMD with administrative privileges.

1. You can do so from the start menu by searching for Command Prompt.

   From the search results, right-click on Command Prompt and choose Run as administrator.

   

   If you are not signed in as admin, you will notice that the User Account Control window opens up.

   Click the Yes button, and the command prompt should open.

2. The are three types of scans that you can perform on your system with Microsoft defender: I.e., Quick Scan, Custom Scan, and Full scan. Let’s start with the quick scan.

   Quick Scan

   The quick scan only scans for the critical areas of your system, such as running processes, system files, and registry keys. This scan is designed to be faster makeing it a good option for regular use.

   To perform a quick scan, you have to change your current directory to the windows Defender installation directory. You can do this using the cd command. Use the command below to navigate to the windows defender installation directory.

   cd C:\ProgramData\Microsoft\Windows Defender\Platform\4.18*
   

   

   Once you are in the right folder, run the quick scan using the following command and hit Enter

   MpCmdRun -Scan -ScanType1
   

   

   You will notice the Start scanning message after executing the command. Once the scan is complete, the message changes to scan finished. And just like that, you have quickly scanned your system using the command prompt.

   Custom Scan

   With the custom scan, you get to specify the files, folders, and drives the defender should scan. This option is useful if you suspect that a particular file or folder has been infected with malware. You can also use this option to examine an external drive.

   To perform a custom scan, open the command prompt and run the command below to change directories to the windows defender installation folder.

   cd C:\ProgramData\Microsoft\Windows Defender\Platform\4.18*
   

   Once you are in the right folder, perform the custom scan with the following command.

   MpCmdRun -Scan -ScanType 3 -File <directory>
   

   Note: Replace the <directory> with the drive you wish to scan.

   Full Scan

   For the full scan, the defender examines the entire system thoroughly. It scans all the files and folders, email databases, external drives, and the critical areas of the system such as the programs loaded at startup, system memory, system backup, and even network drives. This option takes long (hours), depending on the size of the hard drive and the number of files. This scan is more comprehensive and can detect all types of malware and viruses. Ensure you run this scan periodically to keep your system safe from threats.

   To perform a full scan, cd into the Windows defender installation directory as shown above and run the command below.

   MpCmdRun -Scan -ScanType 2
   

   With this command a full scan of your system will be initiated.

Running Full Virus Scan from the GUI.

If you are not comfortable using the command prompt, you can use the graphical user interface to perform the same scans as above. Let us see how.

1. Start by opening the start menu.

2. Search for windows Security and open the top result from the search.

   

3. From there, Open Virus & threat protection.

   

4. A new window should open that has the different types of scan.

   

   You can choose a quick scan from here, and the system will initiate it immediately.

5. If you want to perform the full or custom scan, Choose the scan option to open more scan options.

   

   

Choose the scan type you want and click Scan now. This will initiate the scan and if anything is detected, the Microsoft defender will remove/ quarantine the threats automatically.

Conclusion

Windows defender ensures that your computer is safe from malware. It runs periodically in the background and quarantines any threats found. However, some threats may escape the windows defender. Hence, one should run regular virus scans to maintain the security and integrity of the windows system. By following the steps outlined in this article, you can perform the different types of scans, such as the Quick, Custom, or the Full scans, to ensure that you are safe from malware, viruses, and ransomware.
