How to remove GandCrab virus and restore encrypted files

Our guide was written to assist our readers to delete GandCrab ransomware. On this page, we'll show you everything you have to learn about GandCrab elimination, together with knowledge on the decryption of spoiled data. You'll also see the basic hints about encrypting malware that might help you to avoid problems next time.

Gandcrab ransomware virus

Ransomware is the worst misfortune that might meet you on the Web It is a clear plunder, but with no real robbers involved: hackers get into your machine and take all they wish, leaving a user with a crippled system, filled with wasted data. GandCrab virus is the clearest example of this type of programs: it’s easy to pick up and too difficult to defeat, but there are a few measures that you should take. In today's item, we want to tell you the main patterns of GandCrab's work and how it infested the system. We will tell you what measures you should take to evade encrypting virus' infestation, and how you can get your data back. You need to understand that some the ransomware won't ever get decrypted, so if you've got one – the data may be already gone for good. There's a possibility that hackers made mistakes to leave the switch to neutralize ransomware or to reverse the caused harm. The customer may be guarded by specific options of the OS, and we can explain to you how to take advantage of it.

What is GandCrab ransomware

The point is that modern encrypting programs utilize the unbeatable ciphers, known as the RSA and the AES. They are simply the very complex ones, and you can't decrypt them. Of course, you may decrypt them, having a hundred years of regular machine’s working time or a few years of work on the very efficient computer in the world. We're certain that neither of the given variants suits you. It's time to learn that ransomware are easy to avoid, but if one of them is already on your PC – you are in trouble.

The encoding viruses, also called ransomware, are the programs that infect your machines and spoil their information to earn money for its restoration. In most cases, swindlers get on customer's device via malspam campaigns or 0-day vulnerabilities. E-mail scam is pretty easy to identify – you'll get it suddenly, with a file attached to it. If we talk about zero-day Trojans, it’s way harder – you won’t realize what it will be until you get penetrated so that the most efficient method is to properly update the OS and other utilities which you have in it.

The code of ransomware isn't really complex, yet even the sloppiest virus is highly hazardous, and we’ll explain to you why. It’s all about the mechanisms of encryption. Malicious programs don’t physically grab your files. It simply needs to infect the system, encode your information and eliminate the initial data, leaving the spoiled copies in their place. You can't use those data afterwards. You cannot read the files and cannot return them to norm. We know several ways to reconstruct the data, and they all are described in this item.

As soon as the job is finished, hackers give you a letter with demands, and when you see it – you know that the information is spoiled. There's only one measure you can take now - to erase a virus from your hard drive and concentrate on the data restoration. We've said “attempt” because the odds to deal with it without a decryptor are ghostly.

GandCrab removal guide

It’s essential to eliminate a virus before you start working on file restoration because if it sticks in your system – it will begin encoding any file which enters the hard drive. You should understand that every device you're porting to the spoiled PC will get infected as well. We're certain that you don't want it, so just get rid of the virus via sticking to this useful advice. Don't forget that this will not decrypt the files, and after doing it, you won’t be capable of paying the ransom. We offer you to do that since each ransom gained is making web-criminals more positive in fraud schemes and gives them more budget to create complex ransomware programs. Another point is that if you’re forced to deal with web-criminals, they won't give you a warrant that the data will be restored after you pay the ransom. They have recently ciphered your information, and we don't think that you want to send them more funds after that.

When GandCrab is removed from your device, and you're certain about it, it’s time to consider the recovery techniques. First of all, we want to notice that the only 100% reliable manner is to load a backup. In case you have the backups of the data and the virus is entirely eliminated – don't fret. Erase the encrypted data and upload the backups. In case you had no backups – the odds of restoring the data are slim to none. The only way to succeed is the Shadow Volume Copies. We're saying about the basic service of Windows, and it copies each file that was altered. They may be accessed with the help of custom restoration utilities.

Of course, the modern viruses may delete these files, but if you use a profile without administrator rights, GandCrab just couldn’t do that not having your permission. You may recall that sometime before you've seen a ransom letter you've seen another dialogue window, offering to apply alterations to the OS. If you have declined these alterations – your copies weren't deleted, so you may use them and repair the files via special utilities as ShadowExplorer or Recuva. Both of them may be found on the Internet. Both of them have their official pages, so you should get them from there, with step-by-step guides. In case you require more information about this – simply look at our guide on data repair: article about files decryption.
