What is Revoyem?

Revoyem (also known as DirtyDecrypt) is a malicious ransomware infection which can make you think that you have committed a serious crime and force you to pay the ransom for it. In fact, Revoyem is the entire family of infections, which members are all equal except each of them is set to attack different locations. The first wave of Revoyem attacks has been recorded two years ago in Europe, the United States, and Canada. However, it seems that scammers have started its second wave. Security experts warn that this infection is very well-developed if we can say so. It decrypts the data stored on victim’s computers not for nothing as the majority of ransomwares does. Instead of that, it infiltrates users computers via JavaScrip redirect Trojans and hides in the background of the system doing nothing except causing redirects to illegal websites that usually contain child pornography. Viewing child pornography is considered a huge crime all around the world. Therefore, if the user receives a notification that his/her personal data has been locked for committing this crime, it’s very likely that he/she will fall for believing in that. Sounds scary, we understand. However, you have to keep in mind that your data and screen a locked not by the Police or some other law enforcement authority but by cyber criminals who seek to swindle your money. As far as we have managed to find, Revoyem ransomware is capable of decrypting such file types: .XLS, .DOC, .PDF, .JPG, .PNG. Besides, you may receive a notification window informing you about the crime that you have supposedly committed, file types that have been blocked, and the ransom that you have to pay in within certain period of time in order to get them back. Although you might see paying the ransom as the only way to encrypting information stored on your computer, we have a better solution. In order to remove Revoyem virus, launch SpyHunter or another reputable anti-spyware and run a full system scan. Moreover, in order to recover lost data, you may either use backups or one of the file recovery tools, including R-studio and Photorec.

How can Revoyem hijack my computer?

In the majority of the cases, Revoyem virus infiltrates computers via JavaScript browser hijackers that can be downloaded accidentally from compromised websites or fake software update prompts. Once the hijacker enters a target system, it may start causing redirects to illegal websites that contain child pornography or other content, which once viewed may lead to serious troubles. Besides, such websites are typically filled with Styx Exploit Kit, which is used to transfer Revoyem ransomware and hook it deep in the computer’s system. Once it does so, personal files are decrypted and the user might receive a notification like this:

File is encrypted
This file can be decrypted using the program DirtyDecrypt.exe
Press CTRL+ALT+D to run DirtyDecrypt.exe
If DirtyDecrypt.exe not opened сheck the paths:
C:\Program Files\Dirty\DirtyDecrypt.exe
C:\Documents and Settings\[USERNAME]\Local Settings\Application Data\Dirty\DirtyDecrypt.exe
C:\Program Files (x86)\Dirty\DirtyDecrypt.exe
C:\Users\[USERNAME]\AppData\Roaming\Dirty\DirtyDecrypt.exe
C:\Documents and Settings\[USERNAME]\Application Data\Dirty\DirtyDecrypt.exe

Moreover, the user should also get the message with detailed directories how to perform the payment. If this ransomware has already blocked you from accessing personal data and delivered a ransomware notification such as the one above, take corresponding actions and remove Revoyem virus from the system without any delay. Besides, try to be more careful when surfing the net. DO NOT visit illegal websites, do not open suspicious email attachments since it may be infected, do not click on software update alerts and similar content that is known for spreading serious computer infections unless you are hundred percent sure that the content you are viewing is safe.

How to remove Revoyem virus?

We believe that the most important question for you now is how to recover data that Revoyem virus has decrypted. If you haven’t done backups regularly, then you should install additional software that is designed to recover data, for example, R-studio and Photorec.

After that, make sure that you remove this pesky ransomware from the system once and for all. In order to do so, avoid using questionable third-party anti-malware tools since they will not ensure full Revoyem removal. For this purpose, we recommend using one of these programs: Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, or Malwarebytes Anti Malware

Finally, don’t forget that you computer can easily be affected by various external factors. Therefore, it may be corrupted/damaged one day resulting in data loss. In order to prevent this from happening, regularly backup your files. For that, you can use cloud storage (Google Drove, Drop Box, etc.), USB external drives, CDs, DVDs and so on.
