Remove Blocker Virus (.blocker Files Ransomware)

Blocker – Ransomware

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

The message given by Blocker text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives. It literally mentions that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Sadly, this is definitely true. The sort of cryptography mechanism used by Blocker is still not properly examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

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

Nevertheless, regardless of the asked for quantity, people must stay away from paying the ransom. Cyber frauds are not fair, so they tend to completely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive outcome and people simply lose their money for absolutely nothing.

We highly advise 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 Blocker ransomware and to recover the information data totally free. Hence, the only right decision is to recover the lost information from the available backup.
