Eoeo ransomware. How to remove? (Uninstall guide)

removal by Julie Splinters - - | Type: Ransomware

Eoeo ransomware is a file-locking virus that encrypts data twice

Eoeo ransomware
Eoeo ransomware is a cryptovirus that can encrypt target files twice or more.
 

Eoeo ransomware is a dangerous cryptovirus written in AutoIt scripting language[1]. Malware is using the .eoeo file extension to mark encrypted data. Taking into account the fact that some of these files can be encrypted twice or more, there is no doubt that files with this appendix cannot be used. After the infection, the virus uses the AES encryption[2] method to lock data and then drops the specific extension several times. Encryption keys used in this process are hardcoded and, based on this fact, it should be significantly easier to restore encrypted files. However, it might not be possible since ransomware encrypts files more than once. The Eoeo AutoIt ransomware is using Readme.lol file to notify its victim about the attack which is copied to various locations on the system.

At the moment, EOEO AutoIt ransomware focuses on English-speakers. This virus encrypts everything on the system, even those files which have already been encrypted. When encryption is performed on a file more than once, it becomes impossible to decrypt them. Even the alleged decryption tool which is offered by ransomware developers does not work in this case. 

Since there is no text in the ransom note file, we have no information about the ransom amount or other details regarding the attack. Files' encryption is the main thing ransomware is known for. However, this intruder can do more than you think. If your system is infected with ransomware, it means that the virus can also initiate the following actions behind your back:

  • Lock the screen of your computer and make it impossible to use;
  • Use various computer resources to perform silent processes;
  • Infect the system with other malware;
  • Change Windows registry keys and other system's components;
  • Steal data saved on the system.

You need to remove Eoeo ransomware from the device before it is too late. Since this threat can access the Windows registry, it makes various changes there and modifies existing or adds new registry keys to make sure that virus is launched each time your PC is rebooted. 

If you want to perform a proper Eoeo ransomware removal, you need to employ a reputable anti-malware program which is capable of deleting malware. We suggest Reimage and a few other programs down below for the virus termination and fixing the damage caused by malware. You can also find methods for data recovery below the article.

Researchers[3] always note that you shouldn't pay the demanded ransom and contact cybercriminals behind these threats as this can lead you to money loss or permanent data corruption. Try to focus on the system cleaning process and take precautionary measures if you want to avoid any infection repetition in the future. 

Email spam campaigns can spread ransomware 

If you are not aware of the possible danger behind questionable emails, you can already have a cyber threat on your device. Spam email is one of the most common ways ransomware can be spread around the World Wide Web. Nowadays these emails look safe and legitimate, at first glance, and people without the right knowledge may fall for this. When browsing online in general and in your email box, you should think about the possibility to get a possible threat.

You can look for typos or grammar mistakes on those unknown emails. Commercial content, various ads, and direct in-text-links also indicate that the email is not trustworthy. Especially, if you get, and email from the service you do not use or an unknown company. Malicious people behind these threats tend to hide their product while using known names. Delete questionable emails without opening or at least scan the file before you download it on the computer.

Eliminate Eoeo AutoIt ransomware and clean your PC properly 

To remove Eoeo ransomware and fix all the damage, you should use Reimage, Malwarebytes MalwarebytesCombo Cleaner or Plumbytes Anti-MalwareMalwarebytes Malwarebytes. Anti-malware programs like these can thoroughly scan the system and detect all possible threats. After the scan, this tool indicates which programs are malicious and need to be terminated. After Eoeo ransomware removal, make sure to double-check if there are no malicious programs left. If you used the Safe Mode or System restore to disable the virus, repeat the scan when on normal mode.
