TRO Virus Removal Guide (+Decode .tro files) – Djvu Ransomware

TRO – Ransomware

The TRO mean a ransomware-type infection. The virus comes from the Djvu ransomware family. TRO was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are not able to use them. TRO adds the “.tro” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by TRO, will be renamed into “myphoto.jpg.tro“. As quickly as the encryption is finished, TRO places a special text file into every folder containing the encrypted data.

The message given by TRO text file requesting the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Djvu type. It literally discusses that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by TRO is still not appropriately examined. Still, it is absolutely certain that each victim might be given the specific decryption key, which is completely distinct. It is difficult to restore the files without the key available.

Another technique of TRO is that the victims cannot access to the key. The key is saved on a specific server run by the frauds associated with TRO ransomware. To get the key and recover the important info people need to pay the ransom, which amounts to $980. To acquire the payment information users are instructed to contact the frauds through email or telegram. The alert likewise shows that the users need to contact the TRO developers within 72 hours after the files encryption happened. The message says that doing so users will get a 50% discount, so the ransom amount will fall to $490.

Nonetheless, irrespective of the asked for amount, people must stay away from paying the ransom. Cyber frauds are unfair, so they tend to totally ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people just lose their money for nothing.

We strongly encourage that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack TRO ransomware and to recover the information data for free. Thus, the just best decision is to recover the lost data from the available backup.
