Back is a ransomware virus created to restrict access to important user files through encryption. The ultimate goal of Back is to extort money from its victims by blackmailing them to pay a ransom for a file-decryption key.


The Back Ransomware encrypt your files with the .back extension.

Being infected with a ransomware like Back could be one of the most horrific experiences. You may not only be prevented from access to the information stored on your computer, but there is no guarantee that you will ever be able to recover it again. This alone can be quite stressful and discouraging but, in this post, we’ve decided to provide the victims of Back with some alternatives that could help them remove the infection and potentially recover some of their files. Below is a thorough removal guide with all the instructions and a removal tool for professional assistance.

The Back Ransomware

The Back virus is a file-encrypting ransomware infection that prevents users to access a rather large portion of the data on the compromised device. In this way, the Back virus attempts to get them to pay the hackers behind the virus a ransom for a decryption key.

To extort money from the victims, the criminals use a variety of tactics like setting a short deadline to transfer the required money, doubling the ransom amount or threatening to permanently delete the decryption key which can recover the encrypted information.
Sadly, ransomware infections such as Back represent a terrible threat to any computer with data stored on it. There are several reasons for that and one of them is the way these viruses operate. Typically, those threats can automatically search your entire system and compile a list of specific file types as soon as they reach your device. The target files may include digital documents, images, video or audio files, presentations or executables which get encrypted with a complex code one by one and become inaccessible without a decryption key.

The Back file encryption

The Back file encryption is a process that the Back ransomware carries out in the background of the infected system. The purpose of the Back file encryption is to render a list of specific file types inaccessible so that the hackers behind the ransomware can place their ransom demands.

In this context, it is obviously not the best idea to send money to the blackmailers. Not only does it give them just what they want and allow them to harass people, but also it may not ensure the recovery of the encrypted files. In fact, the hackers may simply choose not to give the decryption key they had originally promised and vanish with the money or keep blackmailing the victims for another payment. And, sadly, you won’t be able to do anything about it. Therefore, our suggestion is to take the initiative in your hands and try to handle the Back infection on your own. For this, we have created a special removal guide below which contains steps on how to remove the ransomware and restore some of your data from system backups. We suggest that you carefully read the instructions and give a try to the free file-recovery steps to see if they can help you minimize the data loss to some extent. We also strongly recommend that you regularly back up your most important files and keep copies of them on a separate drive in order to be fully protected from ransomware attacks in the future.

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.
