Remove EDA2 ransomware / virus (Virus Removal Guide) - Bonus: Decryption Steps

EDA2 virus Removal Guide

What is EDA2 ransomware virus?

New EDA2 ransomware variant wants to receive the ransom as soon as possible

When EDA2 virus hits a computer, expect no good. This ransomware-type computer infection is critical and installing it on the system means losing your personal data permanently. In the ransom note that virus creates and saves on the desktop (DecryptFile.txt), virus’ authors claim to be using RSA-4096 encryption[1] to corrupt data on the target computer, which is extremely strong and undefeatable. Sadly, files encrypted with such cipher can be recovered only by using a special decryption key[2], which cybercriminals suggest buying for 0.15 Bitcoin[3], which is equal to $134. The virus demands to pay up shortly; otherwise the ransom price doubles to $267. In case the victim refuses to pay the bigger price, the virus threatens to destroy the only hope to restore them – the decryption key.

To help the victim understand the extent of encrypted data, the virus marks each encrypted file by adding an extra file extension to it – .L0CKED. Reportedly, other EDA2[4] variants add .ded or .coded file extensions. If you see these file extensions on your files, it means they have been encrypted. Obviously, you might start hesitating whether to pay the ransom or not. There are many reasons why you shouldn’t do so. First of all, paying the ransom doesn’t guarantee that data will be recovered. In many cases, cyber criminals fail to fulfill their part of the agreement and provide the decryption software. We doubt that you want to be left without your files and your money, so we suggest you try data recovery methods described below the article. Second, paying the ransom only fuels criminals’ motivation to continue illegal activities. Therefore, you should think about EDA2 removal instead of searching for ways to obtain Bitcoins. To remove EDA2 malware, we suggest using ReimageIntego or SpyHunter 5Combo Cleaner.

EDA2 ransomware encrypts files

How did this virus slither into my computer system?

Ransomware viruses are usually covered with several obfuscation layers, and they can reach the victim in the form of a malicious link, hideous email attachment, or part of a bogus software update[5]. It is important to understand that relying on common sense might fail to protect your computer since malware developers use very tricky techniques to deceive users and make them install such no-way-back virus. However, you should remember that staying away from vague-looking emails can save your data from malicious attempts to encrypt it. Even if the sender claims to be from Amazon, Paypal, or other legitimate company, double-check the sender’s email and look if the message contains any grammar mistakes (these are the typical points that help to identify a scam). What is more, you should never click on ads hosted on shady third-party websites. Clicking on them can take you to really nasty places on the Internet. If you ever accidentally enter a shady-looking website, better quit it immediately. Finally, beware of malware that travels along freeware and set Advanced or Custom settings when installing software.

How to delete EDA2 virus from the system?

If EDA2 virus has already struck and successfully encrypted your files, there are several different options of what you can do next. You can obey to attackers’ demands and pay the ransom (not recommended), or you can remove EDA2 ransomware from the system and use the backups you have to restore lost data. Sadly, many people do not take care of backups on time, and when ransomware hits their computers, they have no chance to recover lost files easily. If you are one of those victims who do not have a backup, we suggest you follow these data recovery steps that are provided here. However, you should carry them out only after EDA2 removal procedure.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove EDA2 from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by EDA2, you can use several methods to restore them:

Get help from Data Recovery Pro

In case you have no backups, use Data Recovery Pro. This tool might help you to restore lost files.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by EDA2 ransomware;
  • Restore them.

Let the ShadowExplorer find Volume Shadow Copies

Some viruses are programmed by amateur programmers who forget to add a function that deletes Volume Shadow Copies. These copies can be used to restore corrupted files. Use ShadowExplorer to check if Volume Shadow Copies are still on your computer.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from EDA2 and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
