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?
- Press the Windows key + S, type in command prompt, right-click on the displayed result, and select Run as Administrator.
- In the User Account Control window, select Yes.
- 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*
- After navigating to the Windows Defender directory, type in the following to run a quick scan:
MpCmdRun.exe -Scan -ScanType 1
- If you want to run a full scan, type the following command and press Enter:
MpCmdRun.exe -Scan -ScanType 2
- 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.
Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.

- Type in the following command and press Enter:
MpCmdRun.exe -Scan -ScanType 3 -File PATH
- 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:

- Ensure you change the YOURNAME to your username.
How do I run a Boot Sector scan
- Windows key + S, type in command prompt, right-click on the displayed result, and select Run as Administrator.
- 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.

- While in the command prompt, type in the following to view the list of quarantined files:
MpCmdRun.exe -Restore -ListAll

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