Have you ever been attacked by one or more unknown viruses? If you have such an experience, you will know that a virus attack can result in unexpected data loss on a hard drive, external hard drive, memory card, or a USB pen drive.

For users who have no idea how to recover virus infected files from USB, it can be a real disaster! But don't worry! On this page, we will introduce to you two possible solutions to retrieve files from USB: repair and recover virus infected files using CMD and recover virus infected files with a professional data recovery software. These solutions should be executed in succession. If the first one doesn't work out, then continue to the second method. 

1. How to Retrieve Files from USB Using CMD 

When your data is hidden, inaccessible, or lost due to a virus attack on a USB pen drive, your best bet is first trying to use the Command Prompt (cmd) to recover hidden files from virus infected USB. Since it is free and well-understood, cmd is an excellent choice. Now let's see how this works. (I will be using Windows 10 for this demonstration, but the process is largely the same for other OS versions)

1. Plug your external hard drive, memory card, or USB drive into your computer

2. Go to the start menu, type in "cmd" in the search bar, hit enter. You'll then see something named "cmd.exe" under a list of programs.

3. Click "cmd. exe" and then you will be directed to the Windows command line that allows you to recover virus-infected files.

  • Type chkdsk E: /f and hit Enter. (Replace E: with the drive letter of the device or location where you have virus-infected files.)
  • Type Y and hit Enter.
  • Type E: and hit Enter. (Replace E: with the appropriate drive letter.)
  • Type attrib -h -r -s /s /d *.* and hit Enter.  

Windows will then start to repair the virus-infected external hard drive, memory card, or USB drive. The repair usually takes one or two minutes. Please wait patiently. After the repair process, navigate to your disk or card and check if you can see all of the previously virus-infected files on your USB/pen drive, memory card, or external hard drive.

If YES, congratulations! But if not, don't despair. You have another option. Just try a third-party data recovery software in Solution 2!
