How to remove Redboot virus and restore encrypted files

The entry is dedicated to Redboot ransomware that gets into users' laptops in diverse countries of the world, and corrupts their data. Here we've compiled full info about what is Redboot, and how to remove Redboot from your laptop. Except that, we will tell you how to recover the corrupted files and is it possible.

Redboot combinats properties of ransomware and wiper. Virus corrupts files and damages Master Boot Record. It prevents launching Task Manager by using Process.exe file. When encrypting files, Redboot changes the extension of files to .locked. Ransomware had penetrated many laptops around the world through basic method: fraud e-mails with dangerous attachments. Occasionally scammers use exploits to penetrate the computer, but well-known program companies promptly fix them. When infection takes place, Redboot scans the computer memory to find the files for encryption and their approximate worth. Nowadays, each new ransomware knows how to cypher audio, image, video and text information in all most used extensions. High attention is attracted to businesslike documents, since businessmen are the key objective for criminals. Virus encrypts only files with information, and does not affect the programs, so that the user can use the PC to pay the ransom. Encryption is carried out via world-known encryption algorithms, and it is so sophisticated that that it cannot be bruteforced. This is the foundation for unbelievable efficiency of this sort of viruses in last years: an ordinary user, even having a very high knowledge of the computer, will never decrypt the files, and will need to pay ransom. The single way to decrypt files is to find the fraudster's site and retrieve the master key. Some experienced malware researchers can retrieve encryption keys through faults in viruse's program code.

Ransomware virus

There is one thing in common between all types of computer viruses: it's way simpler to avoid it than to neutralize its effects. Statistically, 90% of customers understand the significance of computer literacy only after ransomware infection. To guard yourself, you should understand these few simple principles:

    • Be cautious with the messages that contain files. The #1 template of fraud letters is the story about prize winning or package earning. The second very common sort of such messages is a "business messages". It is OK to be interested and open the letter even if it might be not for you, but don't forget that a single click on the viral file may cost you a lot of headache, money and time.
    • Do not disregard the symptoms that your machine displays. File encryption is a sophisticated act that uses a lot of hardware resources. In few seconds of infection, the CPU performance decreases, and the encrypting process emerges in Process Manager. You can catch this event and switch off the PC before information will be fully spoiled. This, in case of infection, will protect a lot of your files.
    • Don't accept any changes to your computer, coming from weird programs. If the system is penetrated by Redboot, it will endeavour to eliminate the shadow copies of your data, to decrease the possibility of recovery. The removal of shadow copies requires administrator rights and operator's confirmation. Thus, not confirming changes from a unknown software at the proper time, you will reserve the opportunity to decrypt all encrypted data free of charge.

Virus deletion isn't solution of the whole issue - it's only a first turn from many until the total file recovery. If you delete ransomware, you will not get back the data immediately, it will take additional actions described in the next part. In case of ransomware we do not publish the hand uninstall instruction, since its complexity and the possibility of faults is extremely high for regular user. We don't suggest trying to uninstall ransomware manually, because it has many security mechanics which can interfere you. Some viruses can completely erase encrypted information, or some of it, if somebody attempts to uninstall the virus. This is extremely undesirable, and the below guide will help you to deal with it.

After eliminating Redboot from the machine, it only remains to get back the corrupted files. We're not able to reverse the encryption, but we'll get them back via OS features and the particular programs. Ordinarily, to restore the information, you should seek help on targeted forums or from celebrated virus researchers and antiviral program vendors. If you picked the manual information recovery - read our entry, which describes all the most efficient ways.
