You'll also find the common information about encrypting viruses that can help you to avoid penetration in future.

Backup ransomware virus

Backup virus a a part of CryptoMix family. Such type of malware is a typical plunder, but with no alive criminals involved: web-criminals get into the system and grab all they want, leaving a user with an empty hard drive, filled with encrypted files. Backup virus is the brightest instance of encrypting malware: it’s easy to get and almost impossible to remove, but there are a few measures that you should take. On this page, we will explain to you the main principles of ransomware's work and the manners of its penetration into the device. We'll tell you how you can evade ransomware penetration, and what you can do to decrypt your files. Remember that some the ransomware won't ever get decrypted, so one of them is on your PC – the information may be already gone forever. There's a possibility that swindlers made a mistake to leave the approach to neutralize ransomware or to reverse its doings. The user might be protected by specific options of his OS, and we can teach you how to apply it.

What is Backup ransomware and how it works

Regular ransomware programs are not overly complicated in their structure, yet even the most carelessly made virus is very efficient, and we’ll prove our point. It’s all about the methods of encryption. Ransomware doesn't take your information. It simply needs to penetrate the PC, spoil the information and erase the initial data, leaving the encoded copies instead of them. You can't use that data after that. You can’t use the files and cannot bring them to their previous condition. We know not many manners to recover the data, and we've described each of them in this article.

The encrypting malware, also known as ransomware, are the viruses that get into customers' devices and encode their information to gain money for its decryption. The penetration is commonly performed through malspam campaigns or 0-day vulnerabilities. Hazardous mail is very easy to define – you'll get it from an unknown sender, with some files in it. If we talk about 0-day vulnerabilities, it’s a bit more complex – you'll never feel it coming before the machine gets taken over which means that the best defensive manner is to frequently download the newest updates for the system and other utilities which you use.

The thing is that modern encrypting programs use the well-known ciphers, known as the RSA and the AES. They are simply the most sophisticated in the world, and an ordinary user can't decrypt them. Of course, you may decrypt them if you have fifty years of usual computer’s working time or several years of operation on the most efficient machine on the Earth. We really doubt that any of the given options is suitable you. The best method to defeat an encrypting virus is to not let it infect the computer, and we will tell you how to do that.

When the job is done, fraudsters give you the letter "_HELP_INSTRUCTION.TXT" with directives, and is you see it – it's too late. The only turn you can take now - to uninstall Backup from your CP and concentrate on the file restoration. We've said “attempt” as the odds to deal with it without a decryptor are ghostly.

How to remove Backup

You have to delete ransomware before you go on as if it stays in your system – it will start encoding each file that enters the machine. You should realize that each device you are linking to the spoiled device will get encrypted too. To avoid that – eliminate Backup via sticking to our useful advice. Keep in mind that this won’t reverse caused harm, and if you do this, you won’t be capable of paying the ransom. We suggest you to do that because every ransom earned makes fraudsters more positive in what they do and increases their money to develop other viruses. The important thing is that when you’re forced to deal with hackers, they can simply steal the money and ignore you. They’ve just ciphered your files, and you, supposedly, don't want to send them the ransom on top of that.

How to decrypt Backup files

When you uninstall Backup from the machine, and you triple-checked it, you should learn more about the restoration ways. From the very beginning, we should mention that the only 100% proven manner is to have a backup. In case you have the backups of your data and the virus is entirely deleted – don't hesitate. Erase the encoded information and upload the backups. If there were no backups – the probability of getting your files are slim to none. Shadow Volume Copies tool is your lucky ticket. It’s the common service of the Windows OS that copies all the altered or eliminated files. You might reach them via specific restoration tools.

No doubt, the complex ransomware might eliminate these files, but if you use an account without master privileges, Backup just couldn’t do that without your permit. You might remember that sometime before you saw a ransom letter there was another menu, offering to make alterations to the PC. If you have declined those alterations – your copies are at your service, and you can use them and restore the information with the help of custom programs as ShadowExplorer or Recuva. They might be found in the Net. It's better for you to download them from the websites of their creators, with tested instructions.
