.Erif Virus


.Erif is a Ransomware virus that can secretly start an encryption process on your computer in order to lock all of your important data. .Erif runs its encryption with almost no symptoms, which makes noticing the virus in time extremely unlikely.

.Erif Virus

The .Erif Virus will show you this message when your files have been encrypted.

Sometimes, especially on older or not so powerful computers, a Ransomware virus may cause system slowdowns and maybe even freezes and unresponsiveness during the time it is busy encrypting the files of its victims. These symptoms are due to the high amounts of system resources required for the completion of the data encryption. However, even if one notices a certain slowdown in their computer, they might simply assume that it is caused by something else because, after all, system slowdowns due to high use of RAM and CPU could be caused by many things and not only by malware.

Now, if you are here because your machine has already been hit by the malicious .Erif and your files are no longer accessible, in the next lines, we will do our best to help you mitigate this unpleasant situation and deal with the Ransomware problem in the best way possible.

The .Erif virus

The .Erif virus is a newly-reported virus infection recognized as a Ransomware cryptovirus that uses file encryption to deny users access to their own files. The .Erif virus’ purpose is to coerce its victim into paying a ransom for the freeing of their files.

Detailed instructions on what the attacked user is supposed to do according to the hackers are provided inside a message that .Erif creates on the attacked computer right after the encryption is completed. The message, either in the form of a notepad file or a pop-up banner, informs the user about the purpose of the encryption and the way the demanded ransom is supposed to be paid. Usually, the hackers prefer to have the ransom paid in Bitcoins because this cryptocurrency is very difficult to trace, thus allowing the criminals to avoid getting caught. In those cases, the ransom note also includes instructions on how to buy Bitcoins.

Now, if you highly value the files that this virus has locked, you might currently be thinking about making the ransom payment seeing as how this may indeed result in the recovery of your data. However, you must not forget that the hackers could, at any time, decide they won’t allow you to restore your data even after you pay them. Therefore, you should always make sure to first try some other possible options before you actually decide to go for the ransom.

The .Erif file decryption

The .Erif file decryption is a file recovery process that requires a special key in order to unlock the encryption placed on the locked files. The .Erif file decryption key is on the hackers’ computers and they want a ransom payment in exchange for it.

.Erif File

Once the .Erif Virus has infected your system it will start encrypting your files.

We already told you why paying the money demanded by the hackers isn’t a very wise course of action – there’s always a chance you may simply lose the money and not get a working key for the decryption of your files. That is why our suggestion is that you try the guide we’ve posted below – it will help you remove .Erif , after which you can try to recover some of your data on your own. In the second section of the guide, you will find some recovery suggestions that may allow you to bring back some of the data for free if you are lucky.
