DeriaLock is one of the nastiest Ransomware viruses one could encounter and we really aren’t exaggerating here. If you have been infected with it, then most probably the files on your computer have been encrypted with a very strong encryption algorithm and now you can’t access them no matter what you try. On top of that, some crooks have placed a ransom note on your screen and are asking you to pay money to get your files back. What can you do to deal with this malware? Can it be removed? How can you get your files back without paying the ransom? If you’ve been looking for the answers to these questions, you have come to the right place. The guide that you are about to read contains some very useful information about the nature of Ransomware, as well as some detailed instructions on how to remove DeriaLock from your PC. We have also included a few methods that may help you restore some of your data back, so keep on reading to find out more.

DeriaLock Ransomware – a very malicious cryptovirus

Presently, Ransomware is one of the most malicious cyber threats and, unfortunately, a very popular criminal scheme for online blackmail. DeriaLock, which is one of the latest representatives of this malicious type of software, brings all the typical Ransomware features, but in a way more sophisticated manner. Basically, what it does is it uses a very complex secret encryption algorithm to lock all the valuable data on the victim’s computer and then asks a huge amount of money as ransom, to return the files in their previous state.

Usually, an infection with DeriaLock may occur when you least expect it – whether you click on a misleading link or a fake ad, or you open a malicious email attachment or run an installation pack, you would hardly know that you have been infected. This is what makes this threat a particularly nasty one because it usually remains well hidden until its entire encryption process is over and all the files on the infected computer are locked. What is more, the presence of the Ransomware usually means that there might be a Trojan horse on the computer as well. These two dreadful threats – the Trojans and the Ransomware – usually come in a combo when it comes to compromising the users’ computers, and once they are in, they can do a bunch of harmful activities. That’s why they both should be removed from your system as soon as possible.

The DeriaLock decryption key…

One more thing that makes DeriaLock a really nasty threat is that its encryption is very strong to break and in most of the cases, irreversible without the proper decryption key. This means that to return your files to their previous state, you would need only the special decryption key, which is in the hands of the crooks that blackmail you. Whether you will get it or not, however, pretty much depends on their mood and their tricks. You will not see a decryption key unless you first pay the ransom within the given deadlines, and once the criminals get your money, it is up to them to send you the key you paid for. But nobody gives you a guarantee that they will. Actually, in most of the cases, they simply disappear once they get the payment. That’s why security experts strongly advise you against paying the ransom. Better, check for some other options to deal with the Ransomware.

You can seek professional help to remove the malware from your machine, but that may also cost you a lot. One way to deal with DeriaLock without paying anything is to try to remove it all by yourself. For that, you can use the removal guide that we have prepared below. It contains detailed instructions on how to locate and manually delete the ransomware and if you follow them closely, you will not be having any issues at all. Decrypting your files, however, may not be possible. But, not all the hope is lost – what you can do is, you can try to restore some of them from system backups. We will show you how to do that in the same guide below. The best, of course, is if you keep backups somewhere on an external drive or a cloud. This way, once you clean your system from the infection, you can easily bring them back. For future Ransomware protection, make sure that your system is protected with reputable antivirus and you don’t have system vulnerabilities. Always keep your most important data backed up, so even if by any chance you get infected, you won’t lose it the next time.
