Ransomware programs are as bad as viruses get. Currently, they are the ultimate tool for hackers to blackmail their victims without getting caught by law enforcement. Due to the devious tactics and methods utilized by the creators of this sort of malicious software, anti-virus companies are having a hard time devising an effective solution for this rapidly growing issue. At the moment, this is arguably the greatest online threat and it seems to target both regular users and big companies. The ever growing scale of this problem and the release of yet another Ransomware virus called MarsJoke has led us to writing this article, in which we will do our best to keep you informed about this sort of malicious programs

How MarsJoke works

MarsJoke is currently one of the latest Ransomware viruses. Similarly to earlier programs of its family, it can encrypt your files and demand ransom if you want them unlocked. One of the reasons why this type of noxious software is so incredibly difficult to handle is the encryption itself. Generally speaking, encryption is not an inherently malicious process. A lot of normal programs use this on their files. This often makes it impossible for any security software that you might have to make a distinction between a Ransomware encryption and an encryption process of a regular piece of software. This leads to MarsJoke often remaining under the radar of anti-virus programs. It is also one of the major reasons why Ransomware is such a big problem – more often than not it manages to remain hidden until it is way too late and the user’s files have been locked up by the virus.

Ransomware detection

Note that even though your anti-virus program may not be able to identify the threat, you might be able to do that manually. Note that MarsJoke actually needs to copy all your data and it’s actually those copies that have been locked by the encryption. After this stage of the process is over, the virus deletes your original data and leaves you only with the encrypted documents. Oftentimes this sophisticated process takes quite some time and requires considerable amounts of CPU, RAM and free disk space. Due to the heavy consumption of those system resources, you could notice that something malicious is going on if you are vigilant enough. Therefore, make sure that you regularly check your Task Manager and in case you suspect a Ransomware infection, shut down your PC immediately and have it examined by a professional. Also, make sure that you do not connect any portable devices – files on them might get encrypted as well, if there is Ransomware on your PC.

The ransom demand

After the malicious software has done encrypting your data and all your important documents have been made inaccessible to you, MarsJoke reveals itself by displaying a notification on your screen. This notification tells you that you need to pay a certain amount of money to the hacker that’s using the virus if you want to be sent the key that would enable your PC to read through the encryption and access your files. Usually, there are instructions on exactly how to make the transfer.

  • Bitcoins: In the majority of instances the preferred currency for the ransom payment is some sort of cryptocurrency such as bitcoins. This is important to note, since bitcoins are untraceable, which means that the hacker cannot be traced during or after the money transfer. This is one more reason why Ransomware viruses are so popular among cyber-criminals and why the latter almost never get caught.

Paying the money?

If your data has already been locked, we are sorry to tell you that you are not left with a lot of possible options. Paying the ransom is a very bad idea, since you might not even receive the key and simply waste your money. Besides, if you still decide to make the transfer, this would greatly encourage the hacker to keep on blackmailing more and more victims and develop more advanced Ransomware viruses. Therefore, instead of going for that, try out our removal guide beneath this article. It will help you remove the nasty virus and it might be able to restore your files. Even though we cannot guarantee one hundred percent success in all instances due to the particularly devious nature of Ransomware programs, this is still a much better option compared to paying the ransom.

Final advice

MarsJoke will probably not be the last Ransomware virus to be made and the tendency is that these viruses are only going to get more and more advanced. Therefore, make sure to remember and employ the following precaution tips:

  • Get your PC a good anti-virus program since oftentimes Ransomware get inside your system with the help of other viruses such as Trojan Horses.
  • Make sure that all your valuable data has been backed up on a separate device that has no connection to the internet.
  • Avoid going on any illegal and shady sites and do not open any suspicious e-mail letters and hyperlinks that you receive. Use only reliable download sources.
