Voom Virus Removal Guide (+Decrypt .voom files)

Voom – General Info

Voom is a malicious software functioning as typical ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Voom was created for the sole function to encrypt all popular file types. Realistically, as soon as the encryption is successfully achieved, the users are unable to get access to them. Voom virus includes its own “.voom” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Voom, will be titled as “price_list.xls.voom”. As soon as the file encryption is achieved, Voom puts its own special text file (_readme.txt) into all the folders that store the encrypted files.

The alert specified by document requesting the random os really comparable to the notices provided by other ransomware dangers coming from the DJVU family. The warning generally shows that the information has been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely real.

The approach to encrypt the files used by Voom is not completely researched. However, there is no doubt that each computer system owner might be released an unique decryption key, which is definitely unique. It is very difficult to recuperate the data without the suitable key in place.

“Don’t worry, you can return all your files!”, from text file message:

message from Voom virus

One more peculiarity of the Voom infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have introduced the Voom ransomware into the world wide web. In order to acquire the key and bring back the important information, the users are told to contact the scams by means of email or by telegram and to pay the ransom in the quantity of $980.

The message also says that the people need to contact the Voom authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly encourage that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom typically does not result in a successful healing. So, the users might simply lose their money for absolutely nothing.

Likewise, we urge you not to call the frauds as they advise. Do not move money into their wallets. There are no applications that could break the Voom ransomware or bring back the information for free. Therefore, the only right choice is to restore the data from possible backups (if offered).
