There are thousands of nasty threats lurking online, but Cerber 4.0.3 Ransomware is one of the nastiest. This crypto virus is serious trouble for users, who have been infected with its file encryption. As a new addition to the notorious Ransomware family, Cerber 4.0.3 is a very cunning threat that silently infects you and encrypts your files with a strong algorithm. Then, it asks you to pay ransom if you want to access your encrypted data again. This criminal blackmail scheme is something that the world is fighting against, and if you don’t want to give your hard earned money to a group of criminals, you may probably be looking for some other solutions to recover your system and files. This is what we will offer you here – a free removal guide, which is specially created to help you effectively remove the nasty Ransomware from your system. In the next lines, you will learn exactly how to do that.

Cerber 4.0.3 – how dangerous can it be?

When we say that Ransomware is nasty, we really mean it because, unfortunately, this threat is truly harmful to your system and especially your files. Sometimes even security experts are having trouble dealing with this type of malware and combating the new and sophisticated encryption abilities every new cryptovirus comes with. Cerber 4.0.3 is not an exception and as a freshly released threat, it also poses a challenge to the professionals fighting Ransomware encryptions. Here is how its infection process goes:

  • The first challenge for the Ransomware is getting inside your system unnoticed. This is something that Cerber 4.0.3 is specialized in – it often hides in malicious attachments, links or ads that get distributed through spam emails. However, its favorite method is to sneak inside the system through a Trojan horse, which helps it find its way through some system vulnerabilities and remain undetected. Sometimes even security software may not be able to catch the harmful infection on time.
  • Once inside, the cryptovirus starts to scan the infected computer for data storage devices, shared networks and drives. When it detects some targeted files it applies a strong encryption algorithm on them, this way making them impossible to open. The most targeted types of data are usually the most frequently used ones, such as pictures, documents, projects, music, games and sometimes even some system files. What is really bad about Cerber 4.0.3 is that the encryption process usually happens without any visible symptoms that may help the victims prevent the encryption on time.
  • Finally, when all the files are locked, the Ransomware reveals itself on the screen with the help of a disturbing ransom note. This note contains a message from the hackers behind the threat, which requires you to pay ransom if you want to get your files back. They usually promise to send you a decryption key once they get your payment. The amount they ask for, however, may be quite high and usually is demanded in Bitcoins – a special crypto currency that helps the crooks remain undetected by the law.

Why should you remove Cerber 4.0.3 as soon as possible?

If you are infected with Cerber 4.0.3, it would be best to remove it as soon as possible. Unfortunately pleasing the hackers and paying the ransom doesn’t guarantee that you will be able to restore your data. At the end, the only thing they are interested in is getting your money and the likelihood that they would really send you the promised decryption key is really small.

If you keep the ransomware infection on your computer, however, it may harm your system in various other ways, apart from encrypting your files. Remember what we said about the infection – threats like Cerber 4.0.3 usually don’t come alone and they get delivered through a Trojan horse. With this in mind, you should know that your system is now heavily compromised not just by one, but two very harmful malicious programs. It really is up to the hackers’ imagination what they can do to your computer and all the files on it, if you don’t remove the infection on time. And while the aim of the Ransomware is to blackmail you for money, the aim of the Trojan horse is really hard to be defined because the harmful abilities of this threat are literally unlimited and may lead to some truly dreadful criminal deeds. In this case, one option you have is to try to deal with the malware on your own. The removal guide below will help you clean your system from the infection of both the Trojan and the Ransomware. We tried our best to give you a few suggestions on how to extract some of your data as well. However, bear in mind that Cerber 4.0.3 is a really nasty threat and there is no guarantee that you will be able to restore all of your files. The good thing is that it would cost you nothing if you try the steps below, so what is there to lose?
