Ransomware Overview

Ransomware is a sophisticated and insidious type of computer virus that spreads through email, trojan programs, and web pages. It is particularly terrifying and damaging, using various encryption algorithms to infect, delete, and encrypt files.

Ransomware is typically spread through exploits, e-mails, or ads. Once your computer or storage device is infected – as with the notorious Locky, Zcrypt, CryptoLocker, Cerber, CryptWall, or TorrentLocker viruses – you cannot access your infected files or systems unless you pay up.

We recommend not paying the ransom, and even if you do, there is no guarantee that your data will be restored, and you might even end up with more data loss. Thus, after the infection, you can try some quick ways to recover ransomware-encrypted files, e.g., read here how to restore Cerber files. In the next section, we will show you some useful methods to recover files encrypted by ransomware.

Method 1: Use a Professional Virus Attack Data Recovery Tool

Before we get into data recovery, let's look at how most ransomware works.

As you can see in the picture, the encrypted files created by ransomware are not the original ones – they are just copies. The originals are not encrypted directly; they are deleted by the virus. So, you can use data recovery tools to restore the source files that were deleted. As long as the data recovery software finds the deleted source files, there is a chance to recover them.

First, try using the Data Recovery Wizard tool. This is a reputable file-recovery software that can restore files encrypted by the Locky virus (as well as other ransomware like CryptoLocker).

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

Run an antivirus file recovery software on your Windows computer. Select the virus-infected disk and scan for lost or hidden files. Please note that:

• If the virus has hidden or deleted files on your hard disk, it's best to install the software on another partition or external USB drive to avoid overwriting data. • If the infected device is an external hard drive, USB flash drive, or memory card, you can install the software on the local disk of your computer.

Step 2: Review all scan results

The Data Recovery Wizard will immediately start scanning for deleted or hidden files on the virus-infected hard drive. To quickly locate the files you need, you can use the filter or type grouping feature to display only images, videos, documents, emails, and so on.

Step 3: Preview and recover the deleted/hidden files

Once the scan is finished, you can preview the scanned files. Select the files you need and click on the "Recover" button. Save the recovered files to another secure location on your computer or storage device, not the original spot where they were lost.

Ransomware is evolving, and newer, more sophisticated variants may behave differently. They may not delete the original files, so ransomware-data-recovery software won't help.

However, we highly recommend using a data recovery software in case of an infection. Since we cannot determine the type of virus, it is crucial to utilize all available means to restore your data promptly.

If the Ransomware File Recovery tool helped you recover files encrypted by a ransomware virus, share it on social media – Facebook, Twitter, Instagram, and so on!

Method 2: Restore from a System Backup

If data recovery tools do not work, and you happen to have created a system backup, you can try to recover your files encrypted by ransomware using Windows Backup. This way, you can restore your data in case something worse happens. Thus, setting up automatic Windows backups is a useful method to prevent data loss.

Go to the 'Control Panel' and click on 'System and Security' > 'Backup and Restore' > 'Restore my files from a backup'. On the 'Backup and Restore' screen, click on 'Restore my files' and follow the wizard to restore your files.

Method 3: Restore from a “Previous Version”

Previous versions of files can also help recover files encrypted by ransomware.

1. Right-click the file and select "Properties" to find where it's stored.

2. Once the Properties window is up, click on the “Previous versions” tab.

3. A list of available file snapshots will appear. Choose the snapshot that represents the file's known good version.

Click “View” to confirm that it's the correct version of the file. Once you've found the right file, you can:

- View: Preview the recovered file and save it by clicking "File" > "Save As". - Copy: Create a copy of the recovered file in the same directory as the original. You will now have two copies. - Restore: This will restore the recovered file and replace the current one.

Method 4: Run an Anti-virus and Security Scanner

Many computers might be infected with ransomware and held hostage by it. You can download an antivirus tool called TotalAV that can help protect your files from ransomware encryption and assist in the recovery of files encrypted by ransomware.

Step 1. Click on the Download button – “Protect Now”.

Step 2. Click “Yes” in the system dialog box to agree to start the TotalAV installation.

Step 3: Click on the button in the installer window to begin the installation process. Once done, use TotalAV to fix the ransomware error.
