Tuid Virus Removal Guide (+Decrypt .tuid files)

Tuid – Ransomware

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

Tuid was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Tuid ransomware includes its own “.tuid” to all the encrypted files. For instance, the file “price_list.xls”, once crypted by Tuid, will be entitled as “price_list.xls.tuid”. As soon as the encryption is achieved, Tuid puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by _readme.txt requesting for the random os really comparable to the notifications offered by other ransomware threats coming from the DJVU family. The caution basically indicates that the information has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.

The method to secure the files used by Tuid is not completely looked into. However, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely special. It is extremely hard to recover the information without the proper key in place.

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

One more peculiarity of the Tuid 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 criminals who have actually introduced the Tuid infection into the world wide web. In order to acquire the key and restore the important information, the users are informed to contact the frauds by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals should get in touch with the Tuid authors within 72 hours upon the minute of the information encryption. The alert shows that by doing so the people will acquire a 50% discount, for that reason, the ransom amount falls 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 promises, so they may not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts. Thus, paying ransom typically does not result in a successful healing. So, the users may just lose their money for nothing.

Similarly, we urge you not to call the scams as they instruct. Do not move loan into their wallets. There are no applications that might crack the Tuid ransomware or bring back the information for free. Therefore, the only proper decision is to bring back the information from possible backups (if offered).
