This page aims to help you remove GandCrab 5.1 Ransomware for free. Our instructions also cover how any GandCrab 5.1 file can be recovered.

If personal data stored on your computer has recently become inaccessible and if each time you try to open a certain file a message comes up that tells you the file has been encrypted by GandCrab 5.1, then you have most certainly had your machine infected with a Ransomware cryptovirus. You might have already heard about this malicious category of computer threats and about their malicious capabilities but if you presently have such a piece of malware on your machine, then you need to be well aware of exactly how these malicious cyber threats operate and what your available options are at this point in time.

First and foremost, let us go through the most typical characteristics of the Ransomware cryptoviruses for those of you who do not know how these threats operate. A Ransomware cryptovirus (such as GandCrab 5.1) uses encryption on the files of the targeted users and through that encryption it makes the data on the infected PC inaccessible. The purpose of this lockdown is to later be used as leverage upon which the hackers in control of the virus would be able to harass and blackmail their victims and force them to pay a certain amount of money if they wish to restore the access to any of the sealed files. A simple, yet highly effective scheme that is currently one of the most widespread ways of extorting money from PC users through the use of malware.

In most cases, the users learn about the encryption on their files and about the requested ransom sum through a message that the virus itself puts on their screen after it has finished locking-up the files. The message is either generated on the computer’s Desktop or within each folder that contains sealed files. The said ransom-demanding notification also includes exact instructions that are supposed to guide the user through the process of paying the money so that it would be guaranteed that it is exactly the hackers who receive the sum. What’s not guaranteed however is that you’d actually restore the access to your files even if you issue the demanded payment. Remember, there’s always a chance that you might pay and yet receive nothing in return and be thus left with your files locked. This is the reason we have tried to offer you an alternative:

The guide from this page that we have provided our readers with is supposed to help any of you that have the nasty GandCrab 5.1 threat on their machines eliminate the infection and make your PC safe for further use. However, one of the biggest problems with this type of Ransomware threats is that the removal of the virus wouldn’t normally also result in the liberation of the files. Once the encryption is placed on the targeted data, there aren’t really many methods to have it removed. Of course, you can always go for the ransom and hope for the best but as we already mentioned, even this would not guarantee that your data would become accessible again and also, by paying the ransom, you’d be risking your money for a decryption key you might never actually receive. That is why, we’ve done our best to also include in our guide several possible methods that might help you recover some of the encrypted data without they need to pay anything to the cyber criminals who are trying to harass you. Sadly, even the suggested file recovery methods from our guide might not always yield the desired results which is why we can’t promise you that you’d get your files back even if you follow our instructions. It might seem like a lose-lose situation having your files encrypted by Ransomware and sometimes it might indeed be like that which is why those viruses are really some of the worst. Still, you shouldn’t lose hope – security experts are working day and night to come up with better and more effective solutions and as soon as something new comes up that can help users deal with threats like GandCrab 5.1, we will make sure to inform our readers about it.

Defending your computer against Ransomware threats

It’s really important to stay safe on the Internet and to avoid anything that might compromise your PC’s defenses such as spam messages, shady ads, obscure offers, fishy sites and pirated or low-quality downloads. One great tip against Ransomware is to get a backup for any files on your PC that you value since placing copies of them on a backup location or device is sure to keep them safe even in the event of a Ransomware cryptovirus attack on your PC.
