Lokf ransomware (Removal Instructions) - Nov 2019 update

Lokf virus Removal Guide

What is Lokf ransomware?

Lokf ransomware is the cryptovirus that spreads around on Windows devices via cracked and pirated software

Lokf ransomwareLokf ransomware is the virus that encrypts files and appends them using .lokf extensions to show which data is affected already. Lokf is a ransomware virus focusing on encryption because this process allows file encoding. Once the original code is altered and the file becomes useless, the ransom can be asked form the victim. .lokf appendix is the file marker that appears at the end of each altered video, an audio file, picture or document, so people can know that their data is encrypted. Also, once that is done, _readme.txt file appears on the machine in various folders with affected files, on the desktop. The ransom note delivers the text that hasn't been changed since the beginning of Djvu virus family attacks.

Lokf is one of more than 180 versions belonging to this family, and this fact that the threat is no longer decryptable makes the virus more dangerous. At the end of summer 2019, virus developers changed their coding techniques and employed sophisticated algorithms to help with the more difficult file locking.[1] Unfortunately, this is not a good thing for virus researchers and victims. Previously known as the easiest way to unlock files, STOP decrypter, cannot work for any variant released after August, and the recent tool can only work for files encrypted offline keys only.[2] However, Emsisoft Decryptor should be tested after being infected with Lokf.

Name Lokf ransomware
Symptoms Random files get locked and become useless once the .lokf extension appears at the end for identification. The computer runs slower than usual due to additional processes, and the ransom demanding message appears on the screen
Distribution Pirated software, cracks, and cheatcodes distributed online via torrent sites. Also, infected spam email attachments can deliver the malicious code planted on safe-looking MS document[3]
File marker .lokf
Family Djvu/ STOP ransomware
Ransom note _readme.txt is the file that appears in multiple places of the device with encrypted files, so the further actions can be taken
Ransom amount From $490 to $980 in Bitcoin cryptocurrency
Elimination To remove Lokf ransomware and all the possible malware installed beside the cryptovirus, you should employ anti-malware tools and run the full system scan on the machine
Tip for virus damage Since ransomware can interfere with various settings and add files throughout the system, you should also get a tool that might find and repair those system files for you. FortectIntego is the repair tool that should indicate altered or corrupted registry keys and other issues

Lokf ransomware is the cyber infection that scans the machine to find particular file types suitable for data encryption. Your photos, documents, video or audio files, music, databases, or even archives get affected and then marked using .lokf appendix. Encryption changes the original code of the data, and the only possible way to recover the same file is decryption. However, for that, you need a specific key and tool.

Even though virus developers claim to have the needed program, we don't recommend relying on their services. Paying these criminals cannot guarantee that files affected by the Lokf ransomware virus will get restored because these crooks care for your money only.

Stay away from contacting malicious extortionists even though the message delivered in the Lokf ransomware ransom note seems convincing:

The only method that can ensure the recovery of those encrypted files is replacing data with safe copies from the external device or cloud database. If you choose to believe Lokf ransomware developers, you can pay for nothing and lose your money or files permanently. Experts[4] note about the malicious aims of cybercriminals, especially of those that created version after version.

You should remove Lokf ransomware as a threat that this is instead of contacting the criminals. Also, note that the Djvu family launches secondary payloads, installs trojans, info-stealing malware, masks those processes in the background by delivering fake Windows update window. You need to be very cautious and get rid of it as soon as possible.

Lokf ransomware virusLokf ransomware is the version of notorious ransomware known for a while. Unfortunately, decryption tools that exist already are not capable to help with files encrypted by this variant. Lokf ransomware removal and file recovery depend on some major factors related to the coding of the script and the method of encryption. As we mentioned, decryption tools developed before cannot work for files marked with .lokf appendix unless the encryption was achieved with offline keys, so Emsisoft decryptor can be useful.

It is believed that it may take a few years at least to develop a proper decryption program for files affected by Lokf ransomware, so it is not likely that you may get those files recovered ever. You can try to store malware-related files on the external device and wait for the update from researchers, but we are not hopeful.

As for the proper Lokf ransomware virus termination, you should employ anti-malware tools that include this malware family in their database and can indicate the threat once it is on the system. Antivirus tools are not capable of recovering neither system data nor encoded files. You need separate tools to fix the damage and restore encrypted documents.

Since Lokf ransomware creates ransom executables in %AppData% or %LocalAppData% folders and alters Windows registry keys, other parts of the system, you should rely on FortectIntego, software that can perform a system repair and fix the damage caused by infection. These programs might indicate files and programs requiring help and fix the damage for you.

Lokf files virusLokf ransomware is the cryptovirus that is difficult to remove manually, so you should rely on professional anti-malware software.

Infected file attachments and shady programs hide malicious payloads

The more common method used to spread ransomware around involves spam email campaigns when malicious macros get placed on Microsoft Word, Excel or PDF documents and delivered as email attachments, supposedly informing the person about order information, financial data, receipts and shipping details. Malicious senders even pose as DHL, FedEx,eBay, and other legitimate companies to trick people.

However, this particular ransomware family got popular for spreading extremely quickly due to pirated software distribution with payload dropper. Torrent sites and other free sharing networks distribute these packages with cracked programs, video game cheat codes, serial numbers of system tools, and other content that is quickly downloaded by users all over the world.

The only way to avoid the infection is either stop using these services or scan each file coming to the machine with anti-malware tools. These pirating sites sometimes have verification patched for seeders and providers, but even those “legitimate” accounts cannot guarantee what can be included in the pre-packed installer.

Lokf ransomware elimination requires professional tools capable of cleaning the computer fully

There are many dangerous features of this shady Lokf ransomware virus, and most of them are not noticeable because malicious scripts and processes run in the background while affecting important parts of the machine, including security features and file recovery possibilities. These alterations can even damage the machine further than cryptovirus itself.

However, to remove Lokf ransomware as malware and to fix the damage completely, you need proper tools with certain functionalities. Anti-malware programs can be helpful with the termination of this intruder, but encrypted data and damaged system files are not going to be recovered with antivirus tools.

Prepare for the file recovery by employing the trustworthy anti-malware tool for Lokf ransomware removal. For that, get a tool like SpyHunter 5Combo Cleaner or Malwarebytes. Additionally, use FortectIntego to repair affected parts of the system. Once the machine is virus damage-free, you can rely on your data backups or third-party file recovery software to get those files that got encrypted back.

Getting rid of Lokf virus. Follow these steps

Manual removal using Safe Mode

Lokf ransomware elimination should give better results when you reboot the machine in the Safe Mode with Networking before running the AV tool

Important! →
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Lokf 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 Lokf, you can use several methods to restore them:

Data Recovery Pro is the software for your encrypted files

When you cannot use file backups or a decryption tool, you can rely on Data Recovery Pro and restore affected data after Lokf ransomware removal

  • 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 Lokf ransomware;
  • Restore them.

Windows Previous Versions is useful for file restoring

Once System Restore feature gets enabled, you can rely on Windows Previous Versions and recover files individually

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer is the feature on Windows device that allows file recovery without data backups

Shadow Volume Copies should be untouched for the ShadowExplorer to properly work and recover Lokf ransomware encoded files

  • 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.

The decryption tool is still in the development. Check for updates

If your files are encrypted by Lokf ransomware, there is a chance that security experts will update Stop Decrypter or Emsisoft Decrypter to help people who were affected. If you have backups of encrypted data, use them as it is the easiest way to recover encrypted files. However, the first step is to remove the malware from the system.

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

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
