4rw5w is a ransomware cryptovirus that also goes by the name of 4rw5wDecryptor. In some ways it copies the WannaCry virus. Similarities between the two are found in their names, file names, the killswitch embedded in their code etc. The ransom message is written in English, but there is an option to change the language. This ransomware seeks to encrypt only a few file types while placing the extension .4rwcry4w after encryption. Continue to read below to see how you could try to potentially restore some of your files.

4rw5w Ransomware – Infection
4rw5w ransomware is currently in a stasis period, but in the future it might spread its infection via various ways. A payload dropper which initiates the malicious script for this ransomware could be spread around the world. If that file lands on your computer system and you somehow execute it – your computer system will become infected. Malware researchers have found a sample of the ransomware and you can see its detections on the VirusTotal service right here:
4rw5w ransomware might begin distributing its payload file on social media and file-sharing services. Freeware located on the Web can be presented as useful and also could hide the malicious script for this cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything suspicious. You should read the tips for preventing ransomware given in our forums.
4rw5w Ransomware – Overview
4rw5w is a crypting virus which encrypts your files and asks you to pay a ransom to get them recovered. Another name by which the ransomware goes by is 4rw5wDecryptor. A few similarities with the WannaCry virus have been spotted in this ransomware regarding its file names, title name and the embedded killswitch in the code of the ransomware. Here is a list of files associated with the 4rw5w ransomware:
- .4rncry4w
- 3a.4rnkey
- 5d.4rnkey
- t6.4rnkey
4rw5w ransomware could make entries in the Windows Registry to achieve persistence, and probably launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.
The note is written in English, but has an option for translation in other languages. You can view the ransom message that loads after the completion of the encryption process below:
That ransom message reads the following:
4rw5wDecryptor
WARNING

Your important files : photos, videos, documents, etc, were encrypt with our 4rw5w crypt virus.
The only way to get your files back is to pay us 30$ in Bitcoins. Otherwise, your files will be lost.
Caution: Removing of 4rw5w crypt virus will not restore access to your encrypted files.

Decrypt
The ransomware demands 30 US dollars as payment for the ransom. However, you should NOT under any circumstances pay the ransom. Your files may not get restored, and nobody could give you any real guarantee for that. Furthermore, giving money to cybercriminals will likely motivate them to create more ransomware or do other criminal activities.
4rw5w Ransomware – Encryption
The 4rw5w Ransomware encrypts files which have the following extensions:
→.avi, .dll, .doc, .docx, .dot, .dotm, .exe, .jpg, .lnk, .mp3, .mp4, .nef, .odt, .pdf, .pif, .png, .png, .rar, .txt, .url, .wav, .zip
It encrypts them with AES and after that it encrypts that key with the Data Encryption Standard (DES), which is a symmetric encryption algorithm. The extensions given above are around 22 in number, but are also one of the most commonly used ones by each user of Windows. All of the files that get encrypted will receive the same extension appended to them, and that is the .4rwcry4w extension.
The 4rw5w cryptovirus might be tweaked to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your files. If your computer is infected with this ransomware and your files are encrypted, read on to find out how you could potentially recover them.

Step 2: Uninstall 4rw5w and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision.

The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by 4rw5w on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by 4rw5w there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove 4rw5w
Step 5: Try to Restore Files Encrypted by 4rw5w.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
