How to Decrypt a File

Your files on the desktop are being encrypted and the "Encrypt contents to secure data" option is being checked automatically when you move them to other locations. This is likely due to a feature in Windows called "Quick File Encryption" or "Quick Encryption" that is enabled by default. To remove encryption and decrypt files, you can try the following: go to the file properties, click on the "Advanced" button, and uncheck the "Encrypt contents to secure data" option. You can also try using a third-party file decryption tool or seeking assistance from a Windows support professional.

Overview of File Encryption

Windows Encrypting File System (EFS) and BitLocker are two encryption features that protect confidential data from unauthorized access. EFS encrypts individual files and folders, making the file name appear green, while BitLocker encrypts entire drives, providing an additional layer of protection. Both features ensure that sensitive information remains secure, even if an attacker gains physical access to the computer.

Enabling encryption on your drives automatically secures new or existing files and folders with a certificate and private key. This means that any files copied to an encrypted folder will also be encrypted, making it impossible for unauthorized users to access or edit the data.

How to Remove Encrypt Contents to Secure Data  

To remove file system encryption, uncheck the "Encrypt Contents to Secure Data" feature. This only works for the entire file system, not individual files. If you need to decrypt files, a certificate or password is required. For recovering encrypted files without passwords, refer to the linked article.

Step 1. Find the file or folder you wish to encrypt.

Step 2. Right-click the file/folder and click "Properties." Then, click the "Advanced..." button on the General screen.

Step 3. To encrypt the contents of a zip file, go to the "Compress or Encrypt attributes" section and select the box next to "Encrypt Contents to Secure Data". Then, click the "OK" button.

Step 4. An encryption warning box will appear after clicking the "OK" button multiple times.

Step 5. To encrypt the individual file, check the "Encrypt the File Only" box and click "OK".

How to Decrypt a File in Windows 10/8/7

If you have encrypted PDF and Excel files, you can first recover deleted data if they are lost. Then, you can use the methods provided to decrypt and decode them.

How to Remove Encryption from a PDF File

To decrypt a PDF file in Adobe Acrobat, follow these steps. First, you must know the password that was used to encrypt the document.

From there, you can click on "Security" and then "Remove Security" to decrypt the PDF file.

However, keep in mind that removing the encryption will also remove any security features that were applied to the document, such as digital signatures and permissions.

Step 1. Open Adobe Acrobat on your computer.

Step 2. To access the protected PDF file, open it and enter the password when prompted. This will allow you to view and interact with the contents of the file.

Step 3. Click "Advanced" at the top of the Acrobat window. Select "Security" and then click "Remove Security."

Step 4. To confirm the action and remove the encryption, click "OK". Then, press "Ctrl+S" to save the unencrypted PDF file.

How to Remove Encryption from Ransomware Infected Files

If your files are encrypted by a ransomware virus, it's not necessary to pay the ransom. Instead, you can use data recovery software to recover the original, unencrypted files that were deleted by the ransomware, effectively removing the encryption.

Computer viruses typically encrypt files in a three-step process. First, they create a complete copy of all files. Second, they delete the original files. Third, they encrypt the copied files.

How to Restore Ransomware Encrypted File

All you need to do is find reliable data recovery software and try the steps below:

Let Qiling File Recovery Software Help: To recover ransomware-encrypted files, you can use Deep Data Recovery. This software enables the recovery of data from various scenarios, including virus attacks, accidental deletion, hard drive formatting, partition loss, and emptying the recycle bin.

Step 1. Select file types and click "Next" to start

Run Qiling virus file recovery software on your Windows PC. Select file types and click "Next" to start the recovery process.

Step 2. Select the virus infected drive to scan

To scan for lost or hidden files, select the disk attacked by the virus and run a scan. Note that this process may not be able to recover all lost files, and some may be permanently deleted. It's also important to be cautious when scanning for lost files, as some viruses may be designed to make it difficult to recover files, and in some cases, running a scan may make the problem worse.

• If a virus has hidden or deleted files on an HDD, it's safer to install recovery software on a separate volume or an external USB drive to prevent overwriting of existing data.
• If the infected device is an external hard drive, flash drive, or memory card, you can install the software on the local drive of the computer instead.

Step 3. Check all scanned results

Deep Data Recovery starts a scan process to find deleted or hidden files on a virus-infected hard drive. To quickly locate wanted files, you can use the Filter or type grouping feature to display specific file types, such as pictures, videos, documents, or emails.

Step 4. Preview and recover deleted/hidden files

Once the scanning process is complete, you can preview the recovered files, select the ones you want to recover, and then click the "Recover" button. It's essential to save the recovered files to a different location on your computer or storage device, not the original one where they were lost, to ensure their safety and integrity.

After recovering your data, use antivirus software to completely remove the virus, and then regularly back up your important files using Windows scheduled backup software to prevent unexpected data loss.
