Rooe ransomware removal instructions
What is Rooe?
Rooe belongs to the Djvu ransomware family. Like many other programs of this type, Rooe ransomware encrypts files, renames them by appending its extension and creates a ransom note. It renames all files by appending the ".rooe" extension. For example, it renames "1.jpg" to "1.jpg.rooe", and so on. Also, it creates a text file (ransom note) named "_readme.txt" and drops it in folders that contain encrypted files.
As explained in the "_readme.txt" text file, this ransomware encrypts all files (including photos, databases, documents) with a strongest encryption algorithm and unique key. The only way to recover files is by using a decryption tool and key that can be purchased from Rooe's developers for $980. However, it is mentioned that victims who are going to contact them in the first 72 hours after encryption will be able to purchase those tools for $490 (with a 50% discount). These cyber criminals can be contacted via firstname.lastname@example.org or email@example.com email address. Victims have to send them the appointed ID can attach one encrypted file, Rooe's developers offer to decrypt one encrypted file for free. Typically, developers of a particular ransomware are the only ones who have a tool (or tools) that can decrypt files encrypted by their ransomware. In other words, most of the times there are no other tools that could be capable of decrypting victim's files and the only way to get the right tool (and/or key) is to purchase it from cyber criminals. However, it is common that cyber criminals do not send any decryption tool and/or key even if they get paid. Simply said, victims who trust cyber criminals (pay them a ransom) tend to get scammed. Usually the only way to recover files without having to use tools that can be provided only by cyber criminals is to restore them from a backup. It is worth to mention that files remain encrypted even if victims uninstall ransomware from the operating system, its removal only prevents it from causing further encryptions.

Some other examples of ransomware are Prometey, Iwanttits and Crown (Dharma). Usually software of this type is designed to prevent victims from accessing/using their files by encrypting them and create (and/or display) ransom note that contains instructions on how to contact cyber criminals, pay a ransom and/or other information. In most cases there are two main variables: price of a decryption tool and/or key and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt data. Unfortunately, most ransomware-type programs encrypt data with a strong encryption algorithm and it is impossible to decrypt it without the right software and/or key that only cyber criminals who designed the program have. It is possible to decrypt data without their interference only if ransomware is still in a development state (has some bugs, flaws). However, it does not happen often and files can be recover only by restoring them from a backup. Therefore, we recommend to always have data backed up and keep it on a remote server and/or unplugged storage device.
How did ransomware infect my computer?
Usually ransomware and other malicious software is proliferated through spam campaigns, Trojans, unreliable software download sources, software 'cracking' tools and fake software updating tools. It is common that cyber criminals spread malware by sending emails that contain website links that are designed to download malicious files or malicious attachments. Examples of files that they usually attach are Microsoft Office documents, Java Script files, PDF documents, executable files (like .exe), and archive files (like ZIP, RAR). Their main goal is to deceive recipients into opening the attachment (or file downloaded through a link). When opened, that file/attachment installs malicious software. Also, cyber criminals often spread malware through third party downloaders, free file hosting, freeware download pages, Peer-to-Peer networks (like torrent clients, eMule), unofficial pages and other similar sources. They use them to host malicious files. By opening files downloaded through such channels risk to install malicious software. Trojans are programs that usually cause chain infections, they install other malware (e.g., ransomware). However, it can be caused only if a Trojan is already installed on the operating system. Unofficial activation ('cracking') tools are programs that are being used by people who seek to activate software for free (bypass its activation). Nevertheless, these tools often install malicious programs instead of activating some installed software. Operating systems can be infected through fake software updating tools too. These tools cause it either by installing malware instead of updating, fixing installed software, or by exploiting bugs, flaws of some outdated software.

To eliminate malware infections our security researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Attachments and/or links in irrelevant emails that were received from suspicious, unknown addresses should not be opened. It is common that such emails are being sent by cyber criminals who attempt spread malware. It is worth mentioning that they often disguise their emails as important, official, and so on. Software should be downloaded only from official websites and through direct links. Other sources, channels that are mentioned in the previous paragraph should not be used, cyber criminals often use them to host malicious files. Operating system and installed programs must be updated with implemented functions and/or tools that are provided (designed) by the official developers. Various unofficial activation ('cracking') tools can be designed to install malware. Besides, it is not legal to activate licensed programs with various third party tools. Any operating system is safer if it is being regularly scanned with a reputable antivirus or anti-spyware software. Therefore, we recommend to have one installed and always keep it up-to-date. If your computer is already infected with Rooe, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

IMPORTANT NOTE! - As well as encrypting data, ransomware-type infections from the Djvu malware family also add a number of entries to the Windows "hosts" file. The entries contain URLs of various websites, most of which are related to malware removal. This is done to prevent users from accessing malware security websites and seeking help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).
Screenshot of websites added to Windows hosts file:
There are currently two versions of Djvu ransomware infections: old and new. The old versions were designed to encrypt data by using a hard-coded "offline key" whenever the infected machine had no internet connection or the server was timing out/not responding. Therefore, some victims were able to decrypt data using a tool developed by cyber security researcher, Michael Gillespie, however, since the encryption mechanism has been slightly changed (hence the new version, released in August, 2019), the decrypter no longer works and it is not supported anymore. If your data has been encrypted by an older version, you might be able to restore it with the another tool developed by Emsisoft and Michael Gillespie. It supports a total of 148 Djvu's variants and you can find more information, as well as download link and decryption instructions in Emsisoft's official page.

Additionally, Emsisoft is now providing a service that allows to decrypt data (again, only if it was encrypted by Djvu variants released before August, 2019) for those victims who have a pair of the same file before and after the encryption. All victims have to do is upload a pair of original and encrypted file to Emsisoft's Djvu decryption page and download the aforementioned decryption tool (the download link will be provided after uploading files). Note that the file processing may take some time so be patient. It is also worth mentioning that the system must have an Internet connection during the entire decryption process, otherwise it will fail.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Rooe ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Rooe are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Rooe ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
