GruxEr ransomware arrives in a bundle with other two viruses and seeks to extort the victim

GruxEr virus is a 3-in-1 malicious program that seeks to encrypt all of your files with a unique algorithm that renders all files useless. The loader of this ransomware[1] deploys three different programs – TEARS.exe (ransomware that is based on HiddenTear), WORM.exe and GRUXER.exe. During the encryption, the virus corrupts original files but doesn’t change their original file extensions or filenames. The ransomware pays particular attention to JPG files, so it runs a worm that overwrites the beginning of all JPG files and embeds a PNG that displays “Gruxer was here” line. Once the files are encrypted, the virus launches a program window that warns the victim not to shut down the computer and pay $250 in Bitcoins in order to get “personal decryption key.” At the same time, the ransomware drops a ransom note called READ_IT.txt on the desktop. The ransom note says:

Files has been encrypted with hidden tear
Send me some bitcoins or kebab
And I also hate night clubs, desserts, being drunk.

It is clear that this malicious program was developed by someone who is willing to use it as an extortion tool against inexperienced PC users. If you have a reputable anti-malware installed on your computer, and if you keep it up-to-date, you shouldn’t fear this virus because currently, its detection ratio is 51/60, which is really good. However, if it managed to infect your computer, we recommend removing it as soon as possible. Running a system scan with a security software is a must, so we suggest using either Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus software. The first recommended program is capable of optimizing your computer, which makes it the top choice when looking for computer protection/maintenance software.

Ransomware distribution explained

Ransomware is typically proliferated with the help of tricky methods such as malvertising[2], usage of exploit kits or spam mixed with social engineering tactics. Cyber criminals do everything to present malicious files or URLs as safe ones; therefore it is imperative to be aware of the latest tricks they use and of course secure the computer system by installing anti-malware software. Avoid opening suspicious emails sent by people you do not know, and even if the sender claims to be working at Microsoft, Amazon, or PayPal, it doesn’t mean that one actually works there and you can trust him/her. If you suspect that a sender is a person who seeks to deceive you, check his/hers email address online and see if it is associated with any reputable companies. If not, delete such spam right away!

Remove GruxEr ransomware and other malware it installed at once

It is not enough to remove GruxEr virus to clean your computer. As we mentioned before, the ransomware installs two more malicious executive files that you need to get rid of along with other files that were installed by the virus. To gather all of the malicious files and uninstall all of them at once, we suggest using anti-malware software. It is the easiest way to finish GruxEr removal professionally and without having to call a computer technician. We do not recommend you to experiment and try to find virus’ files manually because if you do not have enough computing skills, you can leave your computer vulnerable to malware attacks or even do more harm than good. Ransomware viruses are critical programs that need to be eliminated precisely. Tutorial given below explains how to begin the ransomware removal process.

Bonus: Recover your data

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

When speaking about ransomware viruses, all security experts agree that data backup is probably the only option that is 100% effective when trying to recover files encrypted by a particular virus. Of course, some viruses are so weak that malware analysts manage to crack their algorithms and create a decryption key within a week or so. However, we want to stress out that there are some tools that help to decrypt files encrypted by HiddenTear, although they might not work for GruXer. In such case, try one of the following methods.

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

Data Recovery using Data Recovery Pro

Recovering data after ransomware attack can be tough, but tools like Data Recovery Pro can ease this task for you. Remember that it is a tool that can recover lost or corrupted files, but it might not be that powerful to break encryption used by the ransomware. However, it is still worth a try.

Windows Previous Versions trick

If you have created a system restore point at some point in the past, consider yourself to be a lucky ransomware victim. You can restore your files using this method.

  • 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”.

HiddenTear Decryptors

Use HiddenTear decryption tool presented by NoMoreRansom project, or try this tool provided by Michael Gillespie.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from GruxEr and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
