Rumba ransomware removal instructions
What is Rumba?
Rumba is a high-risk computer infection categorized as ransomware. It is a new variant of Djvu ransomware and was discovered by Michael Gillespie. Programs of this type are designed to encrypt data (rendering it unusable) and keep it in that state unless a ransom is paid. To retrieve their files, users are encouraged to purchase a decryption tool. After encryption, all files are renamed by adding the ".rumba" extension. For example, "1.jpg" becomes "1.jpg.rumba". Instructions about how to decrypt files can be found in the "_openme.txt" text file (ransom message).
Cyber criminals state in the ransom message that Rumba has encrypted all files using the strongest encryption. The only way to retrieve them is to purchase a specific decryption tool. As a 'guarantee' that they have such a tool and can be trusted, the criminals offer free decryption of one file. Furthermore, they even offer a 50% discount to victims who contact them within 72 hours. Victims are encouraged to send them an email via email@example.com or firstname.lastname@example.org containing a personal ID, which is provided in the "_openme.txt" file. Most cyber criminals use encryption algorithms that cannot be 'cracked' without using the correct tool (decryption tool or key). Cyber criminals use cryptographies (symmetric or asymmetric) that generate unique keys. They store these keys on remote servers that can be accessed only by them. The only option remaining is to contact cyber criminals, however, they cannot be trusted. Generally, they ignore victims once ransoms are paid. In this way, people are scammed. The best option in these cases is to use a data backup (if one has been created) and restore everything from there.

Most ransomware-type infections are very similar: they encrypt data and make ransom demands. Common differences are cost of decryption tool and the cryptography algorithm used to encrypt data. Examples of other ransomware-type programs include Dharma-Gif, GrandCrab 5.1, and Obfuscated. Decryption without the involvement of cyber criminals is impossible, unless these programs have bugs/flaws or are still in development. In any case, we recommend that you create regular data backups and store them on remote servers or unplugged storage devices (otherwise ransomware-type programs also encrypt the backups).
How did ransomware infect my computer?
There are several ways to proliferate infections such as Rumba. Most cyber criminals use spam email campaigns, trojans, untrustworthy software download sources, or fake software updaters. They use spam campaigns to proliferate ransomware (or other infections) by sending emails that contain malicious attachments. These attachments are often Microsoft Office documents, PDFs, archive files, executables (.exe files), and so on. Malicious attachments download and install viruses the moment they are opened. Trojans are malicious programs that, when installed, cause chain infections. The main purpose of these programs is to proliferate other infections. Peer-to-peer (P2P) networks (such as torrents, eMule, and so on), freeware download websites, free file hosting websites, unofficial websites and other dubious download sources infect systems by presenting malicious files as legitimate. Using these sources, cyber criminals trick people into downloading and installing viruses. Fake software updaters cause computer infections by exploiting outdated software flaws/bugs or downloading and installing viruses rather than the promised updates, fixes, etc.
How to protect yourself from ransomware infections?
To prevent computer infections with ransomware or other malware, be very cautious when browsing the internet and especially when downloading, installing, or updating software. Never open files (attachments) or links that are presented in emails received from unknown/suspicious email addresses. They are usually irrelevant. Furthermore, download software using official sources and direct download links. Do not use third party downloaders and installers, since they often proliferate rogue applications. Keep software updated using implemented functions or tools provided by the official software developers. Have a reputable anti-virus/anti-spyware suite installed and running - these tools can detect and eliminating threats before any damage is done. If your computer is already infected with Rumba, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

Screenshot of files encrypted by Rumba (".rumba" extension):
Update 22 January 2019 Victims have reported that Rumba has infiltrated their computers through software cracking tools used to bypass the activation of popular programs (such as Photoshop, Cubase, and many others), as well as the Windows operating system. This is a common malware distribution technique: criminals attempt to trick users into believing that these tools will enable them to use copyrighted software free of charge. In fact, these tools give no real value, and using them leads to system infections (in this case, infiltration of Rumba ransomware). Moreover, software piracy is a cyber crime - you are stealing from official software developers. The process is also very risky and often leads to computer infections. Therefore, we strongly advise against the use of pirated software.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Rumba ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Rumba 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 Rumba 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 Rumba 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 as well as 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.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
