Gero Virus Removal Guide (+Decrypt .gero files)

Gero Virus – Details

Gero is a destructive software working as typical ransomware. Michael Gillespie, the widely known virus researcher, very first discovered this new name in the DJVU ransomware family.

Gero was created for the sole function to encrypt all popular file types. Logically, as soon as the encryption is effectively achieved, the users are not able to get access to them. Gero virus adds its own “.gero” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Gero, will be entitled as “price_list.xls.gero”. Once the encryption is accomplished, Gero puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.

The alert stated by _readme.txt requesting the random os really comparable to the notices provided by other ransomware threats belonging to the DJVU family. The caution basically shows that the files have been encrypted 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 secure the files used by Gero is not entirely researched. Nevertheless, there is no doubt that each computer owner might be released a special decryption key, which is definitely unique. It is incredibly tough to recover the data without the proper key in place.

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

Don't worry, you can return all your files! virus

One more peculiarity of the Gero infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the scoundrels who have introduced the Gero virus into the world wide web. In order to acquire the key and bring back the crucial data, the users are informed to contact the scams via email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals should call the Gero authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so individuals will acquire a 50% discount rate, therefore, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no warranty that these online scoundrels will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom typically does not lead to an effective healing. So, the users may merely lose their money for absolutely nothing.

Similarly, we advise you not to contact the frauds as they advise. Do not move loan into their wallets. There are no applications that might break the Gero ransomware or restore the data at no cost. For that reason, the only appropriate choice is to bring back the information from possible backups (if available).
