The Ransomware cryptoviruses are very nasty computer threats which you should keep away from your PC. They can take hostage of your most valuable files via a complex file encryption and blackmail you to pay a ransom in exchange for their decryption. Sadly, new and more sophisticated representatives of this malware category are coming up every day and in this article, we are going to discuss a recently discovered representative of the Ransomware cryptovirus category called .Djvu. If this Ransomware sneaks inside your computer and locks your files with its secret encryption, there might not be many things you could do to release them and remove the infection. However, in the next lines, we have gathered some useful information about the nature of the infection as well as some possible alternatives to the ransom payment which you might be interested in trying out. Our “How to remove” team has also assembled a detailed Removal Guide with step by step instructions on how to locate and eliminate the Ransomware-related scripts from your PC and make it safe for future use. We cannot promise a miraculous recovery, though. A full recovery from the attack of a Ransomware such as .Djvu might not be guaranteed by any method. Sadly, even paying the ransom to the hackers cannot ensure that your computer and your files will be back to their previous state. That’s why, we do not encourage you to risk your money by paying the crooks. What we suggest you do instead is study possible alternative options which you might have and make an informed choice about your future courses of action.
A sneaky infection…
Ransomware is a very dangerous malware form which can infect you in many different ways. The creators of such threats often use seemingly harmless carriers for their insidious software products to deliver the virus in the system and often disguise it using spam messages, malicious email attachments, deceptive links, random free software installers and attractive offers. Many infections may also occur thanks to a previous Trojan horse attack which inserts the Ransomware inside the system without triggering any symptoms. Sadly, a cryptovirus like .Djvu can usually remain under the radar of most security software programs. This is what makes this type of malware particularly nasty – it might not be possible to detect it and stop it before it has completed its malicious encryption to all of your files.
The consequences of a Ransomware’s attack could be really dreadful and unpleasant. Not being able to access your own work files, documents, archives, photos, videos, projects, etc. can really put you in a bad situation. To make things worse, some anonymous hackers place a ransom demanding message on your screen and threaten you that if you don’t pay a certain amount of money within a given deadline, you will never get your data back. This is a very insidious criminal scheme, which, unfortunately, to this date, does not have a universal surefire solution. The victims of Ransomware have to deal with the pressure and the fear of the potential for losing their files as well as to handle the threatening ransom-demanding messages from the the blackmailers. Many agree to risk their money by paying what is required in hopes of receiving the special decryption key from the hackers, with the help of which they should be able to reverse the effects of the harmful encryption. However, there are many people who, despite fulfilling all the ransom demands, never manage to save their files. This is because, unfortunately, the newer file-encrypting viruses such as .Djvu tend to apply very complex encryption algorithms, the reversal of which might not be always possible. The hackers’ decryption key may fail or the crooks may never send it to the victims and just disappear with the money. In such cases, the victims are left alone to deal with the malware and its consequences and only a full backup of their own can guarantee the recovery of the files. This is, so far, the best way to overcome the attack. Basically, if you have copies of your files somewhere on an external drive or on a cloud, the hackers cannot blackmail you and you can easily restore the data to your PC as soon as the threat is removed and there are a number of ways you can get rid of the malware itself (check the guide for further information on how to do that).
I have no backups, what to do?
If you don’t have the habit of keeping regular backups of your data, one thing you could do is to try to extract some backups from your system. In the Removal Guide below we have described how you might be able to do that. Another useful tip is to check all of your email files, mobile devices’ hard-drives and other locations where you might still have safe copies of your important files. However, we first recommend you remove the Ransomware virus from the computer in order to make your future file-restoration attempts safe. The professional .Djvu removal tool on this page can automatically take care of that for you. Also, the guide below has manual instructions that might also help you get rid of the virus if you’d prefer a more hands-on approach. Of course, you can also contact a security professional of your choice, so think about these alternatives and pick the one that fits your case the best.

Remove .Djvu Ransomware
Prior to starting to execute the steps from the guide, we advise you to either bookmark this page or open it on a separate device since throughout the process of completing the guide, you might need to exit your browser.
1: Using Safe Mode
Before beginning to troubleshoot the issue, you are advised to enter Safe Mode on your PC. If you do not know how to do that, use this guide on how to enter Safe Mode.
2: Spotting the process
Open your Task Manager using the Ctrl + Shift + Esc key combination. Next, go to the processes tab and carefully look through the list for any shady entries. Usually, malicious processes will be consuming large amounts of CPU and RAM and will either have no description or will have a suspicious-looking one.
Once you identify the virus’ process, right-click on it and select Open File Location. Delete everything in the folder that opens if you are sure that the process was malicious. If you are not sure, contact us in the comments.
Go back to the Task Manager and end the potentially harmful process.
3: Hosts file IP’s
Go to your start menu and in the search field, paste the following address: notepad %windir%/system32/Drivers/etc/hosts. Select the first result and look at the bottom of the newly opened notepad file. See if there are any IP’s below “Localhost” and tell us in the comments if there were any IP addresses.
4: System Configuration Startup Programs
Type System Configuration in the Windows search bar and open the first result. Go to the Startup tab and take a look at the list of startup programs (on Windows 10, the Startup programs can be seen in the Startup Section of the Task Manager). If any of them look shady or have unknown manufacturer or a manufacturer with a sketchy name, uncheck those entries and click on OK.
Open the Run window (WinKey + R), type regedit and press Enter. Once the Registry Editor opens, press Ctrl + F and type the name of the virus. Select Find Next and delete whatever gets found that has the virus’ name. Do that with all search results.
6: Deleting potential virus files
Open the Start Menu and separately type each of the following locations: %AppData% %LocalAppData% %ProgramData% %WinDir% %Temp% . Open each of those folders and sort their contents by date. Delete the most recent files and folders. When you open the Temp folder, delete everything in it.
