How to remove .Revon file virus

Complete .Revon file virus removal guide

Revon or otherwise called .Revon file virus is a malicious program. It belongs to the infamous Phobos ransomware family.  Like other variants of this family, the Ravon encrypts data and demands payment for the decryption tools/software. During the encryption, it renames the filenames of the encrypted files with the definite pattern: original filename, unique ID, cyber criminals’ email address and the “.revon” extension. For example, a file named “1.jpg” would appear as something similar to “1.jpg.id[1E857D00-2795].[[email protected]].revon”. Shortly after the encryption process is done, the ransomware creates two ransom notes – “info.hta” and “info.txt” and drops them on the every infected folder.

The text file in “info.txt” informs victims that their data encryption and instructs them that in order to recover the affected files they have to write to the email address provided. It states, if no response arrives in 24 hours, they are to use the alternative address. The pop-up window (“info.hta”) provides further detailed information. It is clarified that victims’ letters are to have the ID assigned to them in the subject/title field. They are asked to attach up to five encrypted files to their emails. These files should not exceed 4 Mb in total or contain valuable information (e.g. databases, backups, large excel sheets, etc.). The crooks supposedly offer free decryption of these files as a proof that the decryption tool is working and spending on it can be done.

However, we recommend you avoid paying/contacting to the crooks under any circumstances. These people will never provide you the decryption tool even if all their demands are met. In other word, even after paying the ransom fee, you will not receive the decryption tool and hence the files will remain in the encrypted situation. The crooks are here for their own benefit and to scam the users by fulfilling their demands. You should ignore the ransom payment instruction and must use some data recovery alternatives. The safest option is to remove .Revon file virus and then recover the files using existing backup. The removal is necessary to prevent further files encryption and avoid more severe risks that likely to be caused due to the infection. The removal ensures the data restoration process without the ransomware’s interference.

After successfully removing the threat, use existing backup and restore the affected files to the device. Most of users do not have such backup files. In such a case, the users should rely on some data recovery tools. Nowadays, such tools are designed with special functionality added and so one can anticipate of data recovery using them. Volume Shadow Copy- a cloud created by OS could be an option for the data recovery for you. The problem is that this cloud is most often deleted by ransomware in the process to harden the decryption process. You should however check whether this option is available for you or not from the instruction provided below the post in the data recovery section.
