Gcyi Virus Removal Guide (+Decrypt .gcyi files)

Gcyi – General Info

Gcyi is a malicious software working as common ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.

Gcyi was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively achieved, the users are not able to get access to them. Gcyi virus includes its own “.gcyi” to all the encrypted data. For example, the file “price_list.xls”, when modified by Gcyi, will be entitled as “price_list.xls.gcyi”. When the encryption is achieved, Gcyi puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by _readme.txt asking for the random os extremely similar to the notifications provided by other ransomware hazards coming from the DJVU family. The caution essentially indicates that the information has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely real.

The method to secure the files utilized by Gcyi is not completely investigated. However, there is no doubt that each computer system owner may be provided a special decryption key, which is definitely unique. It is extremely hard to recuperate the data without the suitable type in place.

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

One more peculiarity of the Gcyi ransomware 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 criminals who have introduced the Gcyi virus into the internet. In order to acquire the key and bring back the essential information, the users are told to get in touch with the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message likewise says that individuals must contact the Gcyi authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so individuals will obtain a 50% discount, for that reason, the ransom quantity drops down to $490.

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

Likewise, we prompt you not to get in touch with the frauds as they instruct. Do not move money into their wallets. There are no applications that could break the Gcyi virus or restore the information at no cost. Therefore, the only appropriate decision is to restore the information from possible backups (if offered).
