Remove TerrorWare Virus (.terror Files Ransomware) – HiddenTear Ransomware

TerrorWare Virus Ransomware

The TerrorWare stands for a ransomware-type infection. The infection comes from the HiddenTear ransomware family. TerrorWare was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. TerrorWare adds the “.terror” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by TerrorWare, will be renamed into “myphoto.jpg.terror“. As quickly as the encryption is completed, TerrorWare places a special text file into every folder containing the encrypted data.

The message given by TerrorWare text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the HiddenTear clan. It literally points out that the information is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism applied by TerrorWare is still not correctly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is completely distinct. It is impossible to restore the files without the key available.

Another technique of TerrorWare is that the victims cannot access to the key. The key is stored on a particular server run by the frauds connected with TerrorWare ransomware. To get the key and recover the important information people have to pay the ransom.

However, irrespective of the asked for amount, people must keep away from paying the ransom. Cyber frauds are not fair, so they tend to completely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people simply lose their money for absolutely nothing.

We highly recommend 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 TerrorWare ransomware and to recover the data data for free. Therefore, the just best decision is to recover the lost information from the available backup.
