How to remove Blind virus and restore encrypted files

Blind ransomware already infected hundreds of computers in different parts of the world with help of easiest method: false e-mails with dangerous attachments. Also, scammers use zero-day vulnerabilities to get into the PC, but major program vendors promptly fix them. When infection takes place, Blind checks the hard disc to find the files to be encrypted and their approximate cost. During the encryption, Blind changes the extension of files to file_name.[This email address is being protected from spambots. You need JavaScript enabled to view it.].blind, and requires above 1000$ for file recovery. Virus adds How_To_Decrypt.hta file to each folder. At the moment, any new virus is able to cypher text, image, audio and video info in all known formats. Special attention is paid to businesslike documents, since medium and large companies are the main objective for hackers. Blind targets only files with information, and does not spoil the software, so that the user can pay the ransom with help of an infected PC. The operation is carried out with the help of famous RSA and AES algorithms, and it is so complicated that that it cannot be bruteforced. Such complexity gives base for such an incredible effectuality of ransomware in last years: usual customer, even having a fairly good experience in suchlike things, will never be able to recover the files, and will have to pay ransom. The sole method to get back files is to crack the scam website and obtain the encryption keys. Sometimes it is possible to obtain these keys via defects in viruse's program code.


Blind virus


That item is dedicated to ransomware called Blind that infects customers' laptops around the world, and cyphers the data. In this entry you can find complete info on what is Blind, and how to get rid of Blind from your PC. Except that, we'll explain how to recover the corrupted information and is it possible.


The knowledge of computers is highly significant in our century, because it helps user to defend the computer from undesired programs. For ransomware it's very relevant, because, in contradistinction to regular viruses, when you eliminate ransomware from the PC, the fruits of its doings will stay. To guard your laptop, you should keep in mind these three simple regulations:


    • Carefully study your emails, specifically those messages that have files attached to them. If you don't know who send the message and it notifies about obtaining any prize, a lost parcel or something similar, this might be ransomware. You also should be watchful with business-related letters, especially if the sender's address and the content is unknown. lawsuits, summaries, reports, Bills for products and services and similar sensitive information cannot come accidentally, and the receiver should know the sender. Otherwise, it is a fraud.
    • Don't neglect the signs that your workstation shows. It needs a big part of CPU resources to encrypt the data. If you observe a noticeable fall in workstation capacity or notice a unwanted process in the Process Manager, you should unplug the laptop, load it in safe mode, and scan for ransomware. This, in case of penetration, will guard some of your files.
    • Pay attention to the pop-ups. One of the simplest manners of information recovery is the restoration via Shadow Copies, and fraudsters have added the removal of SC into the default functionality of malware. However deleting of shadow copies requires admin rights and operator's confirmation. The moment of thought before accepting the checkbox can save your files and your money.

Virus removal isn't the happy end - it's just a one move on the long road until the full file recovery. To decrypt the information you'll have to read the instructions in the following paragraph of our article. In case of ransomware we do not give the manual uninstall guide, because its complication and the likeliness of errors is too high for common user. We do not advise you to delete Blind manually, because it has numerous protection mechanisms that could interfere you. Many viruses can totally remove cyphered data, or some of it, when trying to uninstall the program. To neutralize this, follow the instructions below.
