KillerLocker virus Removal Guide

Description of KillerLocker ransomware virus

Be aware of hazardous KillerLocker ransomware virus

Creating ransomware might be a trend nowadays because recently virus researchers discovered another malware – KillerLocker virus. Probably, it’s the worst computer infection that is lurking in the darkest corners of the Internet. Malware might be delivered straight to your inbox, and if you open an infected attachment or link, it will enter the system and start encrypting all your personal files. Once Killer Locker adds .rip file extension, you won’t be able to access any of your pictures, documents, movies or favourite songs. Hackers will deliver a scary offer to purchase a file decryption tool, but they do not reveal the price and keep the mystery. Usually, crooks ask to pay at least 1 Bitcoin that equals a little bit more than 500 GBP. No matter how important your files are, do not look for your credit card! It’s not a wise decision to have business with cyber criminals. Employ a strong malware removal program (e.g. ReimageIntego) and concentrate on KillerLocker removal. Later you can look for free ways to restore corrupted files. Maybe you have backups? In this case, your data is safe!

KillerLocker ransomware uses a traditional encoding strategy. It employs AES-256 algorithm and uses both, public and private, keys. The public key is used for encrypting files, and the private key is necessary for decrypting them. Unfortunately, virus researchers haven’t managed to crack the code and create a free decryptor. The private key is still hidden in the secret hackers’ server. KillerLocker virus informs victims about the attack by delivering a creepy image of a clown. The lock screen includes a ransom message in Portuguese. Therefore, ransomware probably targets Portuguese-speaking countries, such as Portugal, Brazil, Angola, Mozambique, etc. In the ransom note hackers inform that victims have 48 hours to pay the ransom; later all files will be deleted. Cyber criminals can play with victims’ emotions and threaten them to pay. However, do not panic and remove KillerLocker from your PC. Virus elimination does not delete or unlock your files, but your computer will be clean and safe to use. Ransomware might let other malware enter your computer’s system and cause more serious issues.

Invasion of the ransomware

Various ransomware viruses are hiding everywhere and waiting for a perfect chance to infiltrate your computer. There are many ways how file-encrypting viruses spread, but it seems that hackers prefer launching malicious email campaigns. Indeed, computer users often open suspicious attachments and links provided in the spam emails. Cyber security specialists have been talking about the necessity to double check the information before opening any strange links of files for many years. However, the number of successful ransomware attacks are still increasing. It seems people do not want to learn from others’ mistakes. If you want to avoid KillerLocker malware, you have to be careful with emails.

Ransomware might also spread via exploit kits or hide under malware-laden ads. However, KillerLocker is still a new virus, so researchers haven’t found out if it uses these distribution techniques as well. But it is still important to stay away from high-risk websites, clicking on suspicious advertisements, installing questionable software or updates, because there are many active file-decrypting viruses out there.

KillerLocker removal and data recovery

Encountering ransomware is an unpleasant and frightening experience, but you have to concentrate and remove KillerLocker from the system. Virus elimination requires employing a reputable anti-malware program and scanning computer’s system. We recommend choosing one of these programs: ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes. Of course, you can choose any other preferred security tool. To access, update or install anti-malware tools you might have to reboot your computer to Safe Mode with Networking.

As you already know, KillerLocker removal does not recover corrupted files, and there’s still no free decryption tool created yet. However, at the end of the article, you will find few alternative ways that might help to restore locked data.

Bonus: Restore your files

Using the tutorial provided above you should be able to eliminate KillerLocker from the infected device. novirus.uk team has also prepared an in-depth data recovery guide which you will also find above.

The creators of KillerLocker try their best to convince users that paying the ransom is the only option they have to recover corrupted files. At the moment, virus researchers are analysing this ransomware and developing a decryption tool. However, you should not consider paying the criminals, because you can restore at least the most important files.

There are a couple of methods you can apply to recover data encrypted by KillerLocker:

Restoring data with Data Recovery Pro

This tool is not created for decrypting files encrypted by KillerLocker specifically. However, this tool might help to recover at least few important files.

  • Download Data Recovery Pro;
  • Install Data Recovery on your computer following the steps indicated in the software’s Setup;
  • Run the program to scan your device for the data encrypted by KillerLocker ransomware;
  • Recover the data.

Taking advantage of Windows Previous Versions function

If you have enabled System Recovery function earlier, you can advantage of it. This function allows travelling back in time and copy some necessary files. Bear in mind that this method does not recover all your files.

  • Right-click on the encrypted document you want to recover;
  • Click “Properties” and navigate to “Previous versions” tab;
  • In the “Folder versions” section look for the available file copies. Choose the desired version and press “Restore”.

Using Shadow Explorer for data recovery

Ransomware viruses usually delete Volume Shadow Copies as soon as it enters the computer system. However, if KillerLocker virus hasn’t done it, you can try to retrieve files from them. Follow these steps:

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Install Shadow Explorer on your computer following the instructions in the software’s Setup Wizard;
  • Run the program. Navigate to the menu on the top-left corner and select a disk containing your encrypted files. Look through the available folders;
  • When you find the folder you want to recover, right-click it and select “Export”. Also, choose where the recovered data will be stored.

It is strongly recommended to take precautions and secure your computer from malware attacks. To protect your PC from KillerLocker and other dangerous viruses, you should install and keep a powerful malware removal tool, for instance, ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes.

How to prevent from getting ransomware

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Recover files damaged by a dangerous malware attack

Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.

Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.

The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
