Remove Professeur Virus (+Decrypt .Professeur files) – Jigsaw Ransomware

Professeur Virus Ransomware

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

The message given by Professeur text file requesting the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Jigsaw type. It literally discusses that the info is encrypted and that the only way to restore it is to use a an unique decryption key. Unfortunately, this is absolutely true. The kind of cryptography mechanism used by Professeur is still not appropriately examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.

Another technique of Professeur is that the victims cannot get to the key. The key is saved on a specific server run by the frauds connected with Professeur ransomware. To get the key and recover the important info people need to pay the ransom.

Nonetheless, regardless of the asked for quantity, people should stay away from paying the virus. Cyber frauds are unfair, so they tend to entirely 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 outcome and people simply lose their money for nothing.

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