Leex ransomware (virus) - Decryption Methods Included

Leex virus Removal Guide

What is Leex ransomware?

Leex ransomware – a file virus that leaves victim data inaccessible until proper decryption software is used

Leex ransomwareLeex is the ransomware that infects the machine during pirating or torrenting services.

Leex ransomware can infect any device that runs on Windows operating system. Since its demanded ransom amount is relatively low ($980) and it's spread primarily through file-sharing platforms, such as torrent websites, this cryptovirus is aimed at everyday computer users.

When this file-locker is downloaded, camouflaged as the latest game crack, pirated software, etc., and executed, it immediately starts its bidding. All non-system files (documents, databases, pictures, etc.) are encrypted with an army-grade coding algorithm and renamed by adding the .leex extension to original filenames.

Please rest assured that file contents aren't modified. Thus after using a suitable decryption tool, you will be able to use them like nothing ever happened. Threat actors spreading this ransomware try to convince you into paying the ransom by using various persuasion techniques, which are seen on the _readme.txt ransom note found on the desktop:

.leex file virusThe infection is making changes on the machine when needed parts get changed.

Succumbing to the demands of Leex file virus developers would finance their attacks and development of new, more advanced cyber threats and means to distribute them. We can't reiterate this enough – do not forward any money to the cyberthieves.

Instead, use our free, easy-to-use, illustrated instructions to remove the cryptovirus belonging to one of the most proliferate ransomware families – Djvu. It spews out new variations of their vile creations very frequently. This week it's the third one already. The prior variants were the Neer file virus and the Ddsg file virus.

Leex ransomware removal and system repair guides

Before we begin the removal process, you need to extract all encrypted files from your device to a removable, offline storage device. That must be done, as there's a possibility that anti-malware software would flag those files as malicious and suggest you delete them.

Afterward, download the Malwarebytes security software, update it, and perform a full system scan. Its AV engine will detect all files and entries related to Leex file virus, isolate them, and suggest removing them. Please stick to what the security software recommends to delete.

Djvu family ransomware can sometimes block access to security-related pages, preventing you from downloading any necessary removal software and even disable such tools. In this case, you would have to download the recommended program and scan your device's system with it in Safe Mode with Networking. If you require help accessing it, follow these guidelines if you're using Windows 10/8:

Windows 10 / Windows 8

  1. Right-click on the Start button and select Settings.
  2. Scroll down to pick Update & Security.
  3. On the left side of the window, pick Recovery.
  4. Now scroll down to find the Advanced Startup section.
  5. Click Restart now.
  6. Select Troubleshoot.
  7. Go to Advanced options.Advanced options
  8. Select Startup Settings.
  9. Click Restart.
  10. Press 5 or click 5) Enable Safe Mode with Networking.Press F5 to enable Safe Mode with Networking

Once you reboot your infected device in the Safe Mode with Networking, launch SpyHunter 5Combo Cleaner or another reputable antivirus, update it with the latest malware definitions and perform a full system scan to remove Leex virus and all its malicious components completely.

Anti-malware software is a must for all computer users that value their safety, privacy, and money. Making a habit of scanning your device at least a couple of times per week and updating its virus database could save you from similar perils in the future.

Once the threat is removed, you'll have to use another tool to fix all system irregularities caused by the ransomware when it's establishing persistence on your device. It causes various havoc – changes Registry values/keys, modifies host files, deletes Shadow Volume Copies,[1] disables certain software, etc.

There are tons of various system optimizers on the market, but many users praise the ReimageIntego PC repair tool as one of the best and most versatile. It automatically repairs all system-related issues and even deletes tracking cookies stored by deceptive websites.

Therefore, cybersecurity specialists,[2] including us, highly recommend using it on a daily basis. It's free to try it out, so give it a go:

  • Download the application by clicking on the link above
  • Click on the ReimageRepair.exe
  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation processReimage installation
  • The analysis of your machine will begin immediately
  • Once complete, check the results – they will be listed in the Summary
  • You can now click on each of the issues and fix them manually

From here, there are three available outcomes:

  1. Decrypted!” will be shown under files that were decrypted successfully – they are now usable again.
  2. Error: Unable to decrypt file with ID:” means that the keys for this version of the virus have not yet been retrieved, so you should try later.
  3. This ID appears to be an online ID, decryption is impossible” – you are unable to decrypt files with this tool.

We hope that this tool helped you to recover .leex files and that you can reaccess them. Suppose it didn't; please stay optimistic as there are other data recovery options.

Getting rid of Leex virus. Follow these steps

Restore files using data recovery software

Since many users do not prepare proper data backups prior to being attacked by ransomware, they might often lose access to their files permanently. Paying criminals is also very risky, as they might not fulfill the promises and never send back the required decryption tool.

While this might sound terrible, not all is lost – data recovery software might be able to help you in some situations (it highly depends on the encryption algorithm used, whether ransomware managed to complete the programmed tasks, etc.). Since there are thousands of different ransomware strains, it is immediately impossible to tell whether third-party software will work for you.

Therefore, we suggest trying regardless of which ransomware attacked your computer. Before you begin, several pointers are important while dealing with this situation:

  • Since the encrypted data on your computer might permanently be damaged by security or data recovery software, you should first make backups of it – use a USB flash drive or another storage.
  • Only attempt to recover your files using this method after you perform a scan with anti-malware software.

Install data recovery software

  1. Download Data Recovery Pro.
  2. Double-click the installer to launch it.
    Launch installer
  3. Follow on-screen instructions to install the software. Install program
  4. As soon as you press Finish, you can use the app.
  5. Select Everything or pick individual folders where you want the files to be recovered from. Select what to recover
  6. Press Next.
  7. At the bottom, enable Deep scan and pick which Disks you want to be scanned. Select Deep scan
  8. Press Scan and wait till it is complete. Scan
  9. You can now pick which folders/files to recover – don't forget you also have the option to search by the file name!
  10. Press Recover to retrieve your files. Recover files

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Leex 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.
