Cerber 4.0.2 – a virus that’s very hard to be cured

Unfortunately, the program discussed in the article below is not the most pleasant piece of software a user may come across. Cerber 4.0.2 is a Ransomware-based virus that attacks your PC by scanning all your drives and disks in order to find and enlist all the frequently used data. After this activity an encryption process follows – all of the enlisted files are made inaccessible to you one by one. Please note that Cerber 4.0.2 could lock up both folders and separate pieces of data. After this unfortunate process is completed, it is followed by a ransom notification that is broadcast on your screen. Such an alert may contain some extra terrifying threats like payment details (currency and deadlines). The worst part of seeing such a bothering message is that it is not a trick. Everything is true and your system has been made a victim of an awful version of an even more terrible virus family – Ransomware.

What makes such a contamination especially dangerous?

Several aspects of being infected with Cerber 4.0.2 makes this experience truly troublesome. First of all, this virus rarely travels by itself. Typically, it brings a companion. Normally, it is another version of malware – a Trojan. Here come the functions of this incredibly harmful duo:

  • The one to ensure the passage to the system is the Trojan. For this purpose it usually exploits a program or a OS weak spot. Such a weak spot could be an anti-virus tool, the virus database of which has not been updated for a long time. Such an inefficient tool may not perceive the ongoing infection and may not stop this malware company of two.
  • After this, Cerber 4.0.2 immediately gets to work. This form of Ransomware uses a sophisticated encryption on your files, which results in the user not beign able to open them. The only way to unlock them is with a decryption key, consisting of two components. The first component of this key the hackers usually give to you and it might be included in the ransom alert you are later shown. For the second part the hackers demand your money. It is called private and only the code it consists of might recover your blocked data.
  • Despite the fact that the Trojan that came with Cerber 4.0.2 does not do anything noticeable immediately after the contamination process, it might be up to some frightening things like spying on you with your own microphone, web camera or key strokes. Also, it could be programmed to steal all your account and banking details and rob you of all of your money and possessions that you control and manage online. Such a Trojan may even become the reason for identity theft.

Is there a way to both remove the virus and save your encoded files?

To our great disappointment, Cerber 4.0.2 is one of the most hideous viruses out there. Even people who have been working professionally in the malware-removing area may find it especially difficult to both save your data and uninstall this malicious program successfully. Sometimes such a process could end well for the user, sometimes it could end badly. You should know that whatever actions you are up to, you might never see or use your hijacked files again. Nothing and no one can give you any guarantees that your data will be recovered. Our sincere advice is to restrain from paying the money demanded from you as ransom and to look for a possible solution elsewhere. For instance, we have attached a Removal guide below this article. It will help you delete Cerber 4.0.2 and will attempt to recover your files again. Perhaps it won’t be enough. You are already risking your data, so it is always good to experiment a little with different options before making the irreversible decision of paying the ransom.

If no solution guarantees success, what should be done to really deal with Cerber 4.0.2?

Once the infection process is completed, little is really up to you. The moment in which you can counteract this online disease is before the contamination. In other words, prevention gives you the biggest chance of successfully dealing with Ransomware. When it comes to Cerber 4.0.2, the best safety piece of advice is to keep several copies of all your files. Back up as much as you can and as often as you can! Another tip is to stay away from the potential sources of Ransomware, which are mainly emails from unknown or odd senders and their corresponding attachments. Bear in mind that Ransomware might be hiding anywhere – photos, archives, documents, torrents, bundles. Surf in a smart way and your PC will be safe and okay.
