BLOWER Virus Removal Guide (+Decode .blower files) – Djvu Ransomware

BLOWER Virus Ransomware

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

The message given by BLOWER text file requesting the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the Djvu family. It actually points out that the information is encrypted which the only way to bring back it is to use a a special decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by BLOWER is still not correctly examined. Still, it is absolutely certain 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 trick of BLOWER is that the victims cannot access to the key. The key is stored on a particular server run by the frauds connected with BLOWER ransomware. To get the key and recover the important info people need to pay the ransom, which totals up to $980. To get the payment details users are advised to contact the frauds through email or telegram. The alert likewise suggests that the users require to contact the BLOWER developers within 72 hours after the encryption happened. The message says that doing so users will get a 50% discount, so the ransom amount will fall to $490.

Nonetheless, regardless of the asked for amount, people should stay away from paying the virus. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom normally does not provide any positive outcome and people just waste their money for absolutely nothing.

We strongly recommend that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack BLOWER ransomware and to recover the information data free of charge. Hence, the only best decision is to recover the lost information from the available backup.
