This page aims to help you remove Gandcrab v4 Ransomware for free. Our instructions also cover how any .KRAB file can be recovered.

Have you recently received an odd notification similar to this one:

“Your data has been encrypted. In order to have it back, it would be in your best interest to continue reading and provide the necessary payment of *this much money* in *this and this currency* to *this or that account*. In case you fail to proceed with the demanded payment in the time we have given, your encrypted files are going to be lost forever.”?

If yes, then your device has been infiltrated by a Ransomware virus known as Gandcrab v4 Ransomware. In the next few paragraphs, we are going to be discussing all of its unpleasant effects and the possible dangers that might come as a result from the infection such viruses cause. 

Gandcrab v4 Ransomware

 

Stay cautious: the most terrible viruses you can ever face are based on Ransomware:

It is a known fact that Gandcrab v4 Ransomware and its malware group bring serious danger to your PC. No doubt, they are the some of the most dangerous cyber-threats that could ever attack your system.

Are you wondering how these viruses are able to do that? The answer, in a lot of instances, is through the help of another virus program such as a Trojan horse. The Trojan searches for a weakness in your system and the programs installed on it – in case there is such a vulnerability, the backdoor malware will find it and exploit it.

After it’s done that, it unleashes Gandcrab v4 Ransomware inside the attacked device. Once the Ransomware’s inside your system, it will begin executing its insidious agenda.

The Ransomware scans your drives and locates certain files that belong to frequently used formats. Following that, all the predetermined data ends up sealed and inaccessible. An elaborate encryption process is used to lock the files and if the user doesn’t pay the requested money, they wouldn’t receive the decryption key and the data would stay remain for good. In order to inform the user regarding the way the money is supposed to be paid, the malware generates a ransom-requesting note on the infected PC’s desktop.

It is then – immediately after you see the ransom-requesting notification on your monitor – you realise you are being blackmailed. Its content usually looks like the one mentioned in the intro above.

How to Decrypt Gandcrab v4 files

We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here.

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

How is such a virus distributed?

As we all know, the Internet is a dangerous place – almost all the things on it can be possible sources of Gandcrab v4. The favourite hiding places for such a virus are spam emails letters, mainly inside the attachments of those letters. Furthermore, it is common to find such malware inside contaminated web sites and suspiciously-looking torrents, videos, and shareware. No matter how exactly you have come across this Ransomware, it is possible that you have also been infected by a Trojan version.

What to do for dealing with such a horrifying infection?

A universally effective countermeasure for such a virus infection may be practically non-existent. Even the most experienced experts might find it incredibly challenging and time-consuming to handle and deal with Ransomware attacks. There are reasons why such infections must be coped with carefully:

– even eliminating the actual virus infection might not be enough to bring back the hijacked files, and the files might eventually get lost forever. Every user in the position of a victim should make their own decision about whether they want to try removing Gandcrab v4 on their own or try making the payment and risk losing their money for nothing as the hackers might simply decide not to provide them with the needed key for the decryption. Even if the ransom has been fully paid within the given time limit, the online criminals might never give back your access to the affected files. They couldn’t care less about the future of your data after the transaction of your money – they might even get motivated to ask for some more, so carefully consider all other options before paying.

You can act – not to a great extent, but still you may have success:

In all honesty, our advice is to NOT provide the demanded ransom. Indeed, whatever you do, you will risk your encrypted data, so you can, at the very least, try saving your files and removing Gandcrab v4 by using our Removal Guide, which you can find at the end of this article. With hope that it will solve your issues with this malicious program, we can say that it is all we can do to help you. We can’t promise for sure that it’s going to be what you need to recover all your files, however, it’s worth giving it a try!
