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 for virus infected file recovery: 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. 

Solution 1. Use CMD to Recover Files from Virus Infected USB Pen Drive

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 virus infected files. 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!

Frequently Asked Qusetions

1. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

2. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

3. Why isn't it suggested to recover the files back to the original drive?

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.

4. How can I check whether my data is recoverable or not before purchase?

The Free version helps you save 2GB files to better verify the recovery quality of our product before purchase.

5. How long does it take to scan the drive?

It strongly depends on the capacity of your hard drive and the performance of your computer. As reference,most drive recoveries can be completed in around 10 to 12 hours for a 1-TB healthy hard drive in general conditions.
