Without a doubt, Ransomware infections are among the most dangerous type of cyber threats that the world knows. There are so many versions of this malware, and many more appear every day, armed with even more sophisticated malicious abilities. The threat that we are going to speak about today is one of the latest Ransomware nightmares – Cerber 4.1.1 – an advanced cryptovirus with a very strong encryption algorithm, used to lock the victim’s files. Many users, who recently became victims of its nasty infection, have reached our team with a call for help, and here is what our experts have prepared as a solution.

Below, there is detailed information about the nature of Cerber 4.1.1 and its harmful capabilities as well as a removal guide, created specially to help you remove the infection from your computer. The instructions we prepared are as detailed as possible, so anyone can successfully identify the malware and manually delete it from their system without any advanced skills. There is also a professional removal tool, which may come in handy to deep scan and clean your PC. We need to warn you though, that this is very nasty Ransomware and the encryption that it has applied to your files may not be removed even when you successfully clean your system from the malware. However, in the guide below we have included several steps, which may help you extract some of your data from the encrypted computer. So, keep on reading to find out more.

The encryption

As one of the latest representatives of the Ransomware family, Cerber 4.1.1 has a set of harmful abilities. How this malware operates is once it infects your computer, it immediately starts to infiltrate your system for targeted file types. Usually, the files that this Ransomware encrypts are the most commonly used types such as documents, photos, videos, music, games, etc. When detected on your drives, these files become locked one by one with a very strong and complex encryption algorithm that prevents them from being opened or accessed in any possible way. Unfortunately, there aren’t many visible indications that may prompt you to check what is going on with your machine until the damage is done and all the files are encrypted. This is actually the very nasty part about Cerber 4.1.1.

What is nastier, however, is that once the encryption is completed, you are denied all access to your data. The only possible option that is given to you is through a decryption key, which you need to pay for. In fact, this is a well-trained criminal scheme, which the hackers behind Cerber 4.1.1 are applying in order to blackmail the infected victims for money. They will place a ransom note on the screen of the infected computer, claiming their ransom demands (usually in bitcoins), which may vary from a couple of hundreds to a couple of thousands of dollars. Deadlines and various threats and manipulations are not excluded in order to make the victims pay the sum as soon as possible. However, many security experts, including our team, would advise you not to submit to the criminals’ demands as this hides greater risks of real financial losses, without any guarantee that you will restore your encrypted data.

How the infection happens

There are several “preferred” distribution methods when it comes to Ransomware threats like Cerber 4.1.1. From fake emails, well masked malicious attachments, ads or misleading links, to exploit kits and Trojan horses, you may get infected with this nasty threat when you least expect it. The hackers usually rely on users’ curiosity to click on a seemingly intriguing or harmless-looking file, which will actually transmit the malware to the computer without any symptoms. Sometimes, even the antivirus software may react too late to protect the system from such sophisticated Ransomware threats, that’s why it is best to rely on reputable software and update its virus definitions regularly. Or ideally, stay away from sketchy content and avoid clicking on randomly popping notifications, links or spam emails, which may lead you to unknown web locations.

How to remove Cerber 4.1.1?

If paying the ransom is not a solution for your problem, or you simply don’t want to give your hard earned money to a group of unscrupulous hackers, you have all the rights to seek for other methods of dealing with Cerber 4.1.1. In fact, even those who pay may not get the decryption key they have been promised, and may still need to deal with the infection on their own, despite their money loss. It both cases, removing Cerber 4.1.1 is what one needs to do first, in order to eliminate the hacker’s potential attempts to corrupt their system even more. The guide below contains some instructions, which may be of help, so give them a try, as they are free.
