The threat of Ransomware viruses is currently the main concern for the majority of anti-virus companies. This infamous type of viruses is becoming more and more problematic every day, with new versions of it coming out every now and then. At this point, no one is safe from a Ransomware infection and the more valuable data you have stored on your system, the worse a potential infection can be for you. It doesn’t matter if you are a large company conglomerate, an owner of a small business or a regular user – Ransomware hackers attack everyone and every computer with an internet connection is a potential target. If a virus of this type manages to get on your PC, it would then encrypt all your files, making them inaccessible and will then proceed to blackmail you for a ransom payment, if you want the access to your data restored.


Cerber4 is currently one of the latest viruses of the Ransomware family and is also the reason for us to write this article. We believe that with the rapid growth of this malicious threat, our readers need to be well informed about how these viruses work, what makes them so different and difficult to handle and how you can successfully protect your machine from any potential infections. The better understanding one has of Ransomware viruses, the greater the chances of them successfully handling this threat are. Therefore, without further ado, let us introduce you to some of the main aspects of a typical Ransomware program.

How Cerber4 works

There are a number of reasons why this specific kind of noxious software is such a huge issue. First and foremost, it is the fact that those programs, in most cases, do not get detected by any security software that the user might have. This is because there is a distinct difference between the approach of most other viruses and the Ransomware. While the majority of malware out there directly attacks your system with some sort of noxious process that immediately gets recognized as harmful, typical Ransomware employs the method of encryption in order to lock your data without actually damaging it. Encryption processes are used by many normal applications and programs for the protection of their files, thus encryption is generally not seen as something dangerous. Most anti-virus programs are unable to distinguish a regular encryption of non-threatening software from an encryption process carried out by Ransomware. This is how these devious viruses are able to remain under the radar throughout the time they are locking your files.

The encryption takes time!

An important note that needs to be made here is that the Ransomware encryption does not happen in the blink of an eye. It is a sophisticated process that can requires quite some time and system resources depending on how much data you have stored on your machine. The virus first needs to copy everything – it is those copies that are actually locked by the encryption and not the original files. After this stage has finished, Cerber4 makes sure to delete the original documents, leaving you only with the inaccessible copies. However, as we said, this can take a while especially if your PC is not particularly powerful. This gives you the opportunity to prevent the Ransomware from locking at least some of your files. If you notice that your machine is using up unusually high amounts of free disk space, CPU and RAM, you might want to shut it down and get a specialist to have a look at it. Also, if you suspect a Cerber4 infection, you’d better not connect any other devices to your PC since any files in them can also get encrypted.

Is it a good idea to pay the ransom?

If the encryption process is over and your files have already been rendered inaccessible, most Ransomware viruses will display a message on your monitor. This message will tell you that you need to pay a certain amount of money to the hacker if you want to be sent the decryption key, which will enable you to regain access to your data. If that is your case, we advise you to seek another alternative. Not only is there no guarantee that you’d actually get the needed key, but you’d also be encouraging the criminal to keep on terrorizing more and more people with this nasty virus. Beneath this article, you can find a removal guide that could potentially help you remove the noxious Ransomware and possibly even restore your files. Note that because of the unique and devious nature of Ransomware viruses, we cannot guarantee success, but it is still a better alternative to the ransom payment and also one that won’t cost you anything.

How to decrease the threat of a potential Ransomware infection

While there might not be many ways to resolve your problem if your files have already been encrypted, there are quite a few things you can do in order to boost your PC’s protection.

  • A good anti-virus can help a lot for preventing Ransomware infections, because often programs like Cerber4 tend to use backdoor viruses in order to get inside your system. A high-quality anti-virus could prevent this from happening.
  • A data back-up is one of the best precautions against Ransomware attacks, since this can nullify most of their effect.
  • Use your common sense when online. There is no better advice than this one – avoid shady sites, use only reliable download sources, do not open suspicious links, ads and e-mails and so on. In the end, the best protection you can provide your machine with is your ability to avoid exposing it to potential risks.
