A new malicious cryptovirus named .Rumba Ransomware, is waiting for its new victims. This threat has been recognized as a Ransomware virus and although it usually doesn’t spread on other devices the way that a normal virus does, its presence alone can cause a whole lot trouble to your PC and especially to your files. .Rumba can seriously affect your personal or professional life by applying a secret encryption to all the data that you keep on your computer and in this way rendering it inaccessible for an indefinite period of time. The crooks who control the Ransomware use it as a tool for blackmailing. Once their creation has sneaked into the system and has encrypted a list of targeted file types, the hackers demand a ransom payment in exchange for the liberation of the locked data.
If your computer has just become a victim of such an attack, you’re probably wondering how to deal with it and how to save your work documents, personal files, projects, archives, images, videos, audios, etc. Sadly, we need to warn you that, so far, there is has been no universal solution which can guarantee the complete retrieval of the encrypted data. However, there are a few things which you can do to save your machine and maybe some of your files and in the next lines, we will tell you more about these alternatives. Our “How to remove” team has prepared some free file-recovery tips as well as detailed Ransomware removal instructions which, hopefully, can clean your PC from .Rumba Virus and its hidden malicious scripts. Give them a try or explore more alternative courses of action to handle this infection.
How does the attack of .Rumba Ransomware happen?
Ransomware, generally, is a type of malware which doesn’t cause system destruction or corruption. Unlike other viruses such as Trojans, Worms and similar nasty system attackers, this harmful software uses a method called file encryption, with the help of which it simply locks your data and keeps it hostage for a ransom, without actually damaging it. The whole idea of the Ransomware is to make you pay a certain amount of money to regain your access to the sealed files. As you can see, this is nothing but a simple blackmailing scheme which is supposed to generate profits for its criminal creators by surprising the victims and threatening them to never open or use any of the encrypted files if they don’t pay.
Normally, a cryptovirus like .Rumba is really difficult to spot. In order to secretly sneak inside your system and apply its file encryption in complete stealth, this Ransomware often uses sneaky means of distribution such as Trojan horses, fake ads, spam, misleading links, legitimate-looking email messages which deliver infected attachments, exploit kits or similar hard-to-detect carriers. Having reliable antivirus software, in most of the cases, is the only way to catch certain hidden malicious scripts and that’s why investing in a good security tool should be your priority.
Is paying the ransom an option that will save my files?
It is very difficult to predict what would the outcome be if you agree to pay a ransom to the hackers behind .Rumba. Generally, these crooks rely on your fear and frustration to blackmail you and extort as much money as they can. As you already understood, their malware is very difficult to counteract and reversing the complex encryption algorithm may not always be successful. That’s why, the criminals who control the Ransomware will try to scare you, threaten you and push you to pay whatever amount they want (sometimes the ransom demands may reach thousands of dollars!) in exchange for a special decryption key. That decryption key is promoted to you as the only solution which can reverse the encryption of .Rumba and bring your files back to normal. If you decide to trust the crooks and risk your money for that key, however, you should be prepared for various manipulative tricks. For instance, they may not send you the decryption key immediately and may decide to ask you for more money. Or they may send you a decryption key that doesn’t really work and ask you to pay for another one. Or even worse – the hackers may disappear with your money and never reply to you again. Therefore, we believe that paying the ransom should be the last option you should consider and only if you have exhausted all other alternatives.
And what are the alternatives? Well, threats like .Rumba can, indeed, be very difficult to handle. However, if your machine has been attacked, we advise you to find out how to effectively remove the Ransomware scripts and make your system safe and clean again. There are basically two ways to do that – you can either rely on professional antimalware software (such as the one on this page) to detect and remove the malware from the computer or do that manually, by following the instructions of a removal guide. Be prepared for the possibility of your files not getting restored back to normal even after the infection has been removed. That’s why, to recover them, you should rely on your backup copies or try to extract some copies form the system just like its shown in the file-restoration instructions below. Decryption may also be possible after some time if the security experts find out how to break the .Rumba encryption and provide a decryption tool.
|Danger Level||High (Ransomware is by far the worst threat you can encounter)|
|Symptoms||Very few and unnoticeable ones before the ransom notification comes up.|
|Distribution Method||From fake ads and fake system requests to spam emails and contagious web pages.|
Remove .Rumba Virus
Note: Before you go any further, we advise you to bookmark this page or have it open on a separate device such as your smartphone or another PC. Some of the steps might require you to exit your browser on this PC.
2: Task Manager
Press Ctrl + Shift + Esc to enter the Task Manager. Go to the Tab labeled Processes (Details for Win 8/10). Carefully look through the list of processes that are currently active on you PC.
If any of them seems shady, consumes too much RAM/CPU or has some strange description or no description at all, right-click on it, select Open File Location and delete everything there.
Also, even if you do not delete the files, be sure to stop the process by right-clicking on it and selecting End Process.
3: The Hosts file
Go to c:\windows\system32\drivers\etc\hosts. Open the hosts file with notepad.
Find where it says Localhost and take a look below that.
If you see any IP addresses there (below Localhost) send them to us here, in the comments since they might be coming from the virus.
To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.
If you want to avoid the risk, we recommend downloading SpyHunter - a professional malware removal tool - to see whether it will find malicious programs on your PC.
4: Disable Startup programs
Re-open the Start Menu and type msconfig.
Click on the first search result. In the next window, go to the Startup tab. If you are on Win 10, it will send you to the Startup part of the task manager instead, as in the picture:
If you see any sketchy/shady looking entries in the list with an unknown manufacturer or a manufacturer name that looks suspicious , disable those programs and select OK.
5: Registry Editor
Press Windows key + R and in the resulting window type regedit.
Now, press Ctrl + F and type the name of the virus.
Delete everything that gets found. If you are not sure about whether to delete something, do not hesitate to ask us in the comments. Keep in mind that if you delete the wrong thing, you might cause all sorts of issues to your PC.
6: Deleting potentially malicious data
Type each of the following locations in the Windows search box and hit enter to open the locations:
Delete everything you see in Temp linked to .Rumba Ransomware. About the other folders, sort their contents by date and delete only the most recent entries. As always, if you are not sure about something, write to us in the comment section.
The previous steps were all aimed at removing the .Rumba Ransomware from your PC. However, in order to regain access to your files, you will also need to decrypt them or restore them. For that, we have a separate article with detailed instructions on what you have to do in order to unlock your data. Here is a link to that guide.
