JokeFromMars virus Removal Guide
What is JokeFromMars ransomware virus?
JokeFromMars (MarsJoke) virus is a poor knockoff of CTB-Locker virus
According to the latest researches, JokeFromMars virus spreads using even three different names – the previously mentioned one, also MarsJoke and Polyglot. If any of these names look familiar, you should know that you are dealing with ransomware-type infection which mimics an infamous CTB Locker. It is believed that current versions of JokeFromMars malware pose as CTB-Locker in order to confuse malware researchers, however, research shows that these two viruses share no code, but operate in a very similar way. The lock screen that these viruses display is almost identical, besides, both of them allow the victim to test the decryption tool by decrypting 5 selected files. The virus triggers “Request failed” message in case the compromised computer loses Internet connection during attempt to test the decryption tool. It is apparent that the developer of this virus precisely copied modus operandi of CTB-Locker, however, the JokeFromMars virus does not append file extensions to encrypted data. Besides, despite that two years already passed since CTB-Locker first showed up, it is still an undefeated computer threat and nobody can decrypt their files for free. Speaking of MarsJoke ransomware, the developer of it wasn’t precise enough, and malware researchers managed to create a free JokeFromMars decryption tool using a flaw in virus’ source code. You can decrypt your files for free using Data Recovery guide provided below the text. Do not forget to remove JokeFromMars virus first!
How does this virus operate?
MarsJoke ransomware may appear less powerful than other file-encrypting threats, but don’t make a severe mistake by underestimating it. It gets into the system or network as a file_6.exe executable that is used to install a malicious code and launch the ransomware virus. As soon as it becomes active, it encrypts all your files with a strong encryption algorithm (known as AES-256 cipher) and demands ransom in exchange for them. In this sense, it does not stand out much from other samples of ransomware. Nonetheless, it is interesting that MarsJoke virus is spread using the Kelihos botnet which has tripled in size within 24 hours after the virus was released. It only suggests that the cyber criminals have been preparing for the mischief quite some time before the ransomware itself was even launched. And this broad network of “zombie” computers has been accumulated for a very specific reason — to target computers of located in schools, state and local governmental institutions. Unfortunately, this does not mean that your personal computer is safe from this infection. You still might get infected, so you must learn the basic aspects of the JokeFromMars removal. We discuss them later in the article. But if you do not have time for that, obtaining a proper malware elimination utility, such as FortectIntego, should solve this problem automatically.
What is more, the ransomware changes your background picture after the invasion. When the cyber threat succeeds in taking control of the computer, the virus makes sure you get acquainted with the current situation by opening ReadMeFilesDecrypt!!!.txt message which looks like that:
It is clear that MarsJoke virus operates in the same manner as the vast of other ransomware threats. It sets a certain time period within which you should transmit the payment of 0.7 Bitcoin, which currently equals around 421 USD. Of course, the criminals clearly indicate that if the ransom money is not transferred until the deadline, the sum demanded for the files will double or the victim might lose any chance of recovering his/her files entirely. Terror is a common practice the hackers use to convince victims into remitting the payment. Besides, looking at the common practices, there are no guarantees that you will retrieve the files even after paying the ransom. Instead, we offer you to remove MarsJoke and focus on other methods of data recovery.
Less known viruses tend to employ the proof-check technique of placing the infected executables in the spam messages. In order to occupy as many PCs as possible, they present such malicious miles as fake invoices, package delivery reports or tax refund files. Therefore, this distribution method is still highly profitable. JokeFromMars also employs the same techniques. As mentioned previously, it employs a botnet of computers to distribute spam emails with a malicious software attached to them. Usually, the MarsJoke emails its victims a fake flight confirmation document with a malicious executable hidden within. Let us suggest you not to open unknown emails unless you can verify the sender. Even if the email is sent from the governmental institution, keep in mind the possibility of a fraud and always double-check the facts. In addition, you can reduce the amount of received commercial spam or infectious emails by installing a reliable anti-spyware application.

How to prevent from getting ransomware
Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
