Remove Erif Ransomware (.erif File Decryption)

Erif ransomware belongs to a notorious STOP/DJVU clan of crypto-virus that seriously targeting majority of computer user’s files including documents, photos, images, databases, archives, drawings, videos, spreadsheets and so on. After locking the files with highly complex algorithm, Erif ransomware will demand victims to avail the decryption tools and private key, which were priced at $980.

Computer users frequently falls victim to Erif ransomware through spam email messages that pretends to be originating from prominent company or organization. The virus arrives as an attached file on the inbox and the body message persuades recipients into accessing the file claiming that it contains valuable information. Mostly the correspondence is an intriguing context like inquiry, refund, payment, business deals, and similar.

If computer user was tricked to open the attached file, Erif ransomware initiates several attack phase where the first is to download additional malicious files that will run on the computer each time Windows starts. Next, Erif ransomware searches the local drives for common files as specified above and utilize a military grade encryption technique to deny user’s access. Aside from scrambling the core data, it appends the entire infected files with .erif file extension, which is not recognized on any operating system and programs. So, there is no way for users to operate such compromised data.

As final phase of the attack, Erif ransomware informs victim about the ongoing attack by leaving a ransom note. The document also contains instructions on the proper way of decrypting Erif files, which is only possible by paying the ransom demand to acquire the decryption tool and private key. Keep in mind that each victim has its own unique private key; therefore, sharing is not doable. In fact, attackers warn that attempting a different recovery approach for .erif encrypted files may permanently damage it. Here is an excerpt from the ransom note file:

Recover Files from Erif Ransomware Infection

On this section, we will provide ways to decrypt files infected with Erif ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting Erif infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by Erif ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of Erif virus.

Emsisoft Tools

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool
