Hgsh Virus Removal Guide (+Decrypt .hgsh files)

Hgsh Virus Ransomware

Hgsh is a harmful software application working as typical ransomware. Michael Gillespie, the well-known malware researcher, first discovered this new name in the DJVU ransomware family.

Hgsh was created for the sole function to encrypt all popular file types. Logically, as quickly as the file encryption is successfully accomplished, the users are not able to get access to them. Hgsh virus includes its own “.hgsh” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Hgsh, will be titled as “price_list.xls.hgsh”. Once the encryption is accomplished, Hgsh puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by document asking for the random os really similar to the notifications given by other ransomware hazards belonging to the DJVU family. The caution essentially indicates that the files have been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.

The technique to encrypt the files used by Hgsh is not entirely looked into. Nevertheless, there is no doubt that each computer owner might be released an unique decryption key, which is absolutely unique. It is exceptionally tough to recuperate the information without the proper key in location.

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

message from Hgsh virus

One more peculiarity of the Hgsh virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have introduced the Hgsh ransomware into the world wide web. In order to get the key and bring back the crucial data, the users are told to contact the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also states that individuals must contact the Hgsh authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so individuals will obtain a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we highly encourage that you do not pay the ransom. There is no assurance that these online criminals will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom typically does not lead to a successful healing. So, the users may simply lose their money for nothing.

Similarly, we advise you not to contact the frauds as they instruct. Do not move cash into their wallets. There are no applications that could split the Hgsh virus or bring back the data at no cost. For that reason, the only correct decision is to bring back the data from possible backups (if available).
