How to decrypt a file

"When I move files from my desktop to another location, they automatically get encrypted, and the file name turns green. When I check the file properties and go to advanced settings, the 'Encrypt contents to secure data' option is automatically selected without my consent. How can I remove encryption and decrypt files in Windows?"

Overview of File Encryption

Windows Encrypting File System (EFS) is a fundamental file/folder encryption technology that safeguards files in an encrypted state, preventing attackers from stealing confidential data by physically accessing the computer. When a file is encrypted this way, its filename appears in green, as opposed to the usual black text. In addition to EFS, Windows also offers another encryption feature called BitLocker, which protects critical data by encoding logical drives.

Once disk encryption is enabled, new files or existing ones, along with folders, are automatically encrypted on the disk using the certificate and private key. If you copy unencrypted files to a folder with the encryption attribute, they are also automatically encrypted. This prevents unauthorized users from accessing and modifying the data.

How to decrypt files encrypted by ransomware

Aside from encrypting your files actively, ransomware can also encrypt them passively. In such a case, we recommend not paying the ransom and using the Data Recovery Wizard tool to restore the original files deleted by ransomware. This way, you can get the decryption key.

Most computer viruses that encrypt files work in three steps, as you can see in this screenshot. Step one, they make a complete copy of all your files; step two, they delete the original files; step three, they encrypt the copies. So if your computer gets infected, you'll see your files being encrypted in real time.

How Does the Virus Automatically Encrypt Files

How to recover files encrypted by ransomware

All you need is to find a reliable data recovery tool and try the following steps:

Let file recovery software help you: To restore files encrypted by ransomware, you can use the powerful Data Recovery Wizard Pro. This file recovery tool can help you recover data from virus attacks, accidental deletion, formatted hard drives, lost partitions, and emptied Recycle Bins.

Step 1: Select the virus-infected disk to be scanned

Run an antivirus file recovery software on your Windows PC. Select the disk that was affected by the virus to scan for lost or hidden files. Note that:

    • If the infected files are on a hard drive that is hidden or deleted due to a virus, it's best to install the software on a different volume or an external USB drive to prevent overwriting data. • If the infected device is an external hard drive, a flash drive, or a memory card, it's fine to install the software on the local disk of your computer.
Select the location to scan

Step 2: Review all scan results

The "Data Recovery Wizard" will immediately start scanning your virus-infected hard drive for deleted or hidden files. To quickly locate the needed files, you can use the "Filter" or "Group by Type" option to display only images, videos, documents, emails, and so on.

Select deleted or lost files to recover

Step 3: Preview and recover the deleted/hidden files

Once the scan is finished, you can preview the files that were found. Select the ones you need and click the “Recover” button. You should save the recovered files to a different secure location on your computer or storage device, not the original spot where they were lost.

Recover files from virus attack

After the data recovery, continue to run your antivirus software to remove any viruses and ensure your computer is clean. We strongly recommend that you regularly back up important files to prevent unexpected data loss. You can do this manually or automatically using the Windows Backup and Restore software.
