Gosw Virus Removal Guide (+Decrypt .gosw files)

Gosw Virus – Details

Gosw is a malicious software application functioning as common ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.

Gosw was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively achieved, the users are not able to get access to them. Gosw virus adds its own “.gosw” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Gosw, will be titled as “price_list.xls.gosw”. Once the file encryption is achieved, Gosw puts its own special 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 alerts provided by other ransomware hazards coming from the DJVU family. The caution generally shows that the information has been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.

The approach to encrypt the files utilized by Gosw is not entirely investigated. Nevertheless, there is no doubt that each computer owner might be provided a special decryption key, which is definitely distinct. It is exceptionally difficult 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 Gosw 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 total control by the criminals who have actually released the Gosw ransomware into the web. In order to acquire the key and restore the essential data, the users are told to get in touch with the scams by means of email or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that the people ought to contact the Gosw authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so the people will get a 50% discount, for that reason, the ransom quantity 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 scoundrels will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. Thus, paying ransom typically does not lead to a successful recovery. So, the users might merely lose their money for nothing.

Likewise, we urge you not to call the frauds as they instruct. Do not move loan into their wallets. There are no applications that might break the Gosw virus or restore the information for free. Therefore, the only appropriate decision is to bring back the information from possible backups (if offered).
