Erenahen Virus

The Erenahen Virus will encrypt your files

Getting infected with data-encrypting Ransomware (.Meds, Moka) is not a nice thing. The web users or the companies who become victims of this type of malware are typically deprived of the access to their most needed files, while, at the same time, they are asked to pay a ransom in exchange for a decryption key. In many cases, the hackers behind the Ransomware viruses pretend to be legal authorities, and tend to scare the web users into believing they themselves have committed some type of illegal action, which they have to pay a fine for. A recently reported infection of this type goes under the name of Erenahen and operates as a cryptovirus which secretly applies an encryption to the files, stored on the compromised computer, and asks for a certain amount of money in order to make them accessible again. Immediately after the attack, the hackers who have control of the infection place a ransom-demanding notification on the screen and threaten that if no payment is made, the files will remain inaccessible forever.

If you are reading this because you have been greeted by such a message, you may be feeling shocked and intimidated.  Luckily, since you are on this page, we assume that you are most likely seeking an effective course of action that can help you avoid the ransom payment. That’s why, on this page, we have prepared some alternative methods which don’t involve giving your money to the hackers. Just stay with us, and you will find a step-by-step removal guide, which you can use to remove Erenahen, and potentially recover some of the encrypted files by alternative means.

Specifics of the Erenahen virus

Computer infections such as Erenahen operate in a very specific way and this gives them a great advantage over most other viruses. Unlike infections like Spyware, Trojans or Rootkits, this malware rarely damages anything in the system. Instead, it uses file-encryption, which is, in fact, not a harmful process, as its main weapon. Here, we need to say that the file-encryption is one of the most reliable and unbreakable data-protection methods, which has a wide implementation in many sectors such as banking, insurance, health care, and other areas where digital data should be kept away from unauthorized access. The encrypted information can only be opened or used by the person who holds the corresponding decryption key. Ideally, this is the owner of the information. In the case of a Ransomware infection, however, the hackers are those who possess the decryption key, and they blackmail the victims to pay a ransom if they want to obtain it.

Dealing with the Erenahen file encryption?

As you can see, this horrible blackmailing scheme is all about extorting money from the shocked and desperate web users. Unfortunately, even paying the ransom does not give any guarantee about the future of the encrypted files. The hackers oftentimes vanish with the money without sending a decryption key. This risk, combined with the fact that sending money to the attackers only stimulates them to create more Ransomware gives, us a good reason to believe that paying the ransom is not a good idea. Therefore, we often advise our readers to seek alternative options, which focus on removing the malware instead of paying criminals.
