RSA-4096 Ransomware Virus - How to Remove?

RSA-4096 is a name of encrypting algorithm, which is used by hackers all over the world. Most often they use it exactly in ransomware. So, RSA-4096 is also the name of one of the most known encrypting viruses in the Web. It is also known as TeslaCrypt, or Tesla ransomware. This virus is very strong, as well as its encryption, so if you’ve encountered it – your files are in great danger and, maybe, they are already lost. We offer you the instructions about the removal of this virus, the possible ways to recover your files, and few useful advices to ensure the security of your system in future.

RSA-4096 ransomware

Nowadays there are lots of viruses on the Internet. They are very different, some of them are more dangerous than others, but the most threatening thing that user can see on the screen of his PC is the message “Your files were encrypted by the powerful encryption algorithm, give us money to recover them”. Such viruses are called ransomware, because they penetrate your PC, encrypt all files and demand ransom for their recovery. If you find ransomware on your home PC, you can think that it is a bad luck, but think positively: if you’ll find ransomware on your workstation, and the local network of the company that you work in will be infected by virus – the losses might be hundreds of times greater. Anyway, if RSA-4096 is on your PC – you should act swiftly, and get rid of it until the situation became worse.

What is RSA-4096?

RSA-4096 AKA Tesla is one of the most dangerous viruses that can infect the regular user’s PC. It affects all types of files which are commonly stored on our computers, such as text, audio, video and images. The encryption algorithm that it uses is very strong, and it can’t be decrypted without a key. Virus penetrates the PC via viral e-mail attachment, installs itself and begins to encrypt files. You have to understand that if the virus sneaked on your PC – it already won. The encryption process begins immediately after the installation, and RSA-4096 acts stealthy, in order to be unnoticed until the encryption process will be completed. After that, virus displays you its message:

RSA-4096 ransomware

It’s sad to say, but almost every word in this message is true. The only decent way to recover the files after such encryption is the load of backups. The backup had to be made before the virus has penetrated the PC, and in the moment of penetration, the external hard drive with backups must be disconnected from PC. If all of these conditions have been met – the backups will be good, and you can use them after the removal of virus. You may think that if your files are really important, it is better to pay the ransom, but we strongly recommend you not to do that. The hackers, to which you are going to pay the ransom, are the ordinary criminals. They don’t attack you in the dark of the night, don’t take your watch and wallet, but they are absolutely identical to all burglars and thieves in one thing: they have no conscience. If you will pay the ransom – their mission will be complete and, likely, you will never see your money and your data again. In all other cases, you also have no guarantee that your files will be restored. Anyway, we will tell you about all possibilities to recover your data, even if they aren’t 100% efficient. But first thing you should do is to remove the virus itself.

How to remove RSA-4096

Despite the fact that the removal of the virus is a relatively simple process, it is required to perform. If you are going to recover the data using one of the methods described in this article, you will need to first remove the virus from your computer. This can be done manually or with the help of antivirus. Both methods are equally reliable, but manual removal is much more difficult to accomplish. If you are not experienced enough to remove the virus manually, you should use the second method. We advise you to use Spyhunter Antivirus. Removing RSA-4096 using Spyhunter will take you only 10-15 minutes, and you do not need to perform any complicated operations, which means that you won’t make a mistake. Spyhunter will do everything for you, quickly and efficiently. Furthermore, Spyhunter can further protect your system from viruses, and you won’t suffer from their effects.

If you want to delete the RSA-4096 by hand, please use our instructions, which describe each step of the process in detail.

How to decrypt the files

If you are still reading this, then you have no backups, and we will not explain about them once again. Except the backups you have only two possible ways to recover the data: use special decryptor, or recover files from the shadow copies. Both of these methods have their drawbacks. RSA-4096, as well as other strong viruses constantly receives updates. Hackers add new features and make changes. So, depending on what version of the virus has penetrated your PC, it may be either susceptible or resistant to decoding using special programs. At the moment, the best program for the recovery of files encrypted with RSA-4096 is TeslaCrypt decryption tool from Cisco Talos Security.

Restoring using Shadow Volume Copies are also not ideal. Some viruses can delete shadow copies of encrypted files before showing the ransom message to user. This depends on the version of virus, the settings of PC, and user’s attention. However, you should use this method if you have no other choice. To make the most effective use of shadow copies, you will need a special program. We offer you two programs that do an excellent job with similar objectives: these are Recuva and ShadowExplorer. You can download them at the links provided free of charge. Also, you will find detailed instructions on their use on the official websites.

If you follow the advices written in this article, then you know how difficult it is to correct the effects of ransomware infection. Such viruses have to be stopped before they enter the system, and it completely depends on you. No antivirus software will protect you from viruses if you will act irresponsibly on the Internet, and visit untrustworthy sites. Carefully choose the content that you download to your PC, update your antivirus software regularly, and let your computer be free of viruses!
