With each passing day the number of Ransomware virus attacks becomes greater. This malicious type of programs is currently one of the most feared and problematic threats that one can encounter online. Their rapid evolution and spreading combined with the fact that most anti-virus programs are utterly unable to detect such viruses often makes them very difficult to deal with. That is why our readers need to be well informed about the different aspects of Ransomware. The following article will inform you about how these programs work, what makes them so problematic and what your options are if your PC has already been infected by any of them. Cerber 4.0 is currently one of the newest Ransomware viruses, thus we will be focusing on it. A program such as Cerber 4.0, similarly to other viruses of its kind, can encrypt your files with a sophisticated code, rendering them inaccessible until the ransom is paid to the hacker behind the malicious software.

What makes Ransomware and Cerber 4.0 so devious?

There is a significant difference between the approach employed by Ransomware and most other malicious programs. While more conventional viruses are prone to directly attacking your system, which often gets them detected by security software, Ransomware actually uses a process that is in itself not inherently malicious. This process is called encryption and the reason why it often remains under the radar of most anti-virus tools is because there are many legit programs that use encryption for their files. However, your computer is able to read through that encryption. In contrast, if your documents get encrypted by Ransomware, you are unable to access any of them, because the key for the decryption is held by the hacker, who later demands ransom from you in exchange for that key. A Ransomware encryption is often very sophisticated and even big anti-virus software companies are struggling to decipher the codes used by the more advanced viruses of this type. This is yet another reason why Ransomware is such a huge issue. Additionally, the ransom payment is oftentimes demanded in bitcoins. Due to the fact that this cryptocurrency usually cannot be traced, hackers who blackmail people that way can remain anonymous, without fear of ever getting caught. Therefore, more and more Ransomware viruses are being created and with each new version they are becoming more evolved and effective.

Manual detection

Since we have already figured out that anti-virus programs are often not capable of detecting Ransomware, the only option to spot a potential Cerber 4.0 infection would be to do it manually by paying close attention to what’s happening with your PC. If you notice unusually high CPU and RAM usage or that there is less free disk space on your hard drive than you were supposed to have, then this might be an indication of a Ransomware infection. That’s because these viruses do not simply place their encryption on your data. They first need to copy all the targeted files, making the copies encrypted. After having done so, the Ransomware deletes the original documents and the user is left with the encrypted copies. This process requires some time and during this time you can spot the malicious activity by noticing the aforementioned symptoms. In case this happens to your PC and you think it might have been infected by Cerber 4.0, immediately shut down your machine and bring it to an IT professional. That way you’ll be able to save at least part of your data from getting locked by the Ransomware. Also, make sure not to connect any portable devices in a last minute attempt to transfer your files to a safe place, because the virus can get on that device as well, making everything even worse.

Ransom transfer?

If your files have already been locked, you’ll likely receive a message generated by the virus and displayed on your screen. In this message you’ll be told that the only way to get your data back is to pay the ransom money. Instructions on how to make the transfer are usually provided in that message. If that is your case, you will need to make a choice: pay the money or seek an alternative. Neither option guarantees that you would get your files back. However, we believe that going for the ransom payment is a really bad idea. Not only is it unsure if you’d actually be sent the encryption key, but you might be also wasting your money by sending them to an anonymous cyber-criminal. Therefore, we have provided our readers with another possible option. Below this article you can find a removal guide that may help you remove the virus and restore your data. While it might not be able to deal with every Ransomware program, it costs nothing and could potentially save you both time and money.

Stay safe!

The best advice that we can offer our readers is to stay safe and not let those malicious viruses get inside their computers. That is why we advise you to read and make a mental note of the following tips that would enhance your virtual security.

  • Oftentimes Ransomware gets distributed via malicious hidden links and spam e-mails. Thus, if you stumble upon any suspicious-looking e-mails or hyperlinks, do not open them!
  • Illegal sites are another common method for spreading malicious programs – make sure you only visit reputable sites and download software from trustworthy sources.
  • Get your PC a good and reliable anti-virus program, since Ransomware often reaches the user’s computer through some other backdoor virus that an anti-virus program should be able to detect and intercept.


Name Cerber 4.0
Type Ransomware
Danger Level High (Ransomware is by far the worst threat you can encounter)
Symptoms  If your PC gets infected with this malicious virus, it’s likely that there will be a severe system slowdown during the encryption period. The slowdown is caused by high CPU, RAM and free disk space usage from the Ransomware.
Distribution Method Normally, Ransomware gets spread through malicious e-mails and hyperlinks that get send to users, infected downloadable content on illegal sites and with the aid of other viruses that have previously infected the victim’s system.
Detection Tool

Keep in mind, SpyHunter’s malware detection tool is free. To remove the infection, you’ll need to purchase the full version.
