About .Dutan File Virus

Nowadays, data, especially digital data, is one of the most valuable resources which is why protecting it is so essential and important. And though the methods of keeping one’s important and valuable data safe are currently more accessible and easier to employ than they’ve ever been in the past, there are still many users out there who seem to forget just how essential it is to ensure that any important files they may have on their computers are kept safe. One of the most popular and easy to apply methods of protecting important files is the backup – it basically allows you to have intact copies of all of your valuable pieces of data on a location that is typically safer than your computer. However, there is still an overall lack of proper backups and this is is precisely what allows file-encrypting Ransomware viruses like .Dutan (which is the latest successor of the strain that includes .Hofos, .Roldat, .Todarius and .Verasto) to thrive. Infections like this one have one single goal and that goal is to make all potentially important files in the targeted machine inaccessibly by employing a special, highly advanced encryption process. Ironically, the process of encrypting files is actually another very popular data-protection method that many people use to add an extra layer of security to their important files. However, when used by a cryptovirus Ransomware such as .Dutan (, this same helpful process gets turned at 180 degrees and becomes a tool of blackmailing and money extortion.

Since in most of the cases the only thing capable of unlocking an encrypted file is the unique key that corresponds to the applied encryption, the hackers behind viruses like .Dutan are able to blackmail their victims for that key, demanding a ransom payment in exchange for it. Usually, there would be some specific steps that need to be followed to complete the payment for the decryption key and those steps are explained within a ransom-demanding note that gets shown on the infected computer’s screen once the files on it are no longer accessible. Some hackers may even tell their victims that they would decrypt a a couple of their files for free in order to prove that they do indeed have a working decryption solution. Oftentimes, the victims of such an infection would be given a deadline, after which the decryption key would (supposedly) get destroyed or the demanded sum of money would go up.

So, is the payment of the ransom a viable option

Normally, we wouldn’t advise you to go for this course of action as it hides many risks, the most obvious of them being the risk of simply wasting the money you send as the criminals blackmailing you may easily decide to keep the key and not send it to you. Also, even if you pay and get your data back, the malware may still be left in your computer and cause issues in the future. Therefore, we advise you to use the steps we’ve provided in the removal guide for .Dutan down below and, through them, eliminate the infection. After that, you can try some of the suggested alternatives of data recovery – though they may not always work, they are still worth the try.

Remove .Roldat Ransomware Virus (+ File Recovery)

.Roldat – Details

If you are on this page, this is most likely due to a recent infection with a threat called .Roldat. This threat operates as a Ransomware cryptovirus and won’t spare any of the files that you store on your HDD. Once it finds its way into your computer, the malware will infiltrate the entire OS and look for certain file-types that it will secretly encrypt. Next, .Roldat will generate a ransom-demanding message on the screen of the infected computer and will ask the victim to pay a certain amount of money in exchange for a special decryption key.

The text that you are about to read now, however, explains to the victims of his cryptovirus how they can deal with the consequences of its attack, how to safely remove the harmful code from their system and what they can do to protect themselves from it as well as from other similar threats. Our “How to remove” team has assembled a set of instructions and posted them below that will show you the exact removal steps that you need to take if you want to effectively get rid of .Roldat, as well as some file-recovery suggestions that may be able to recover the files that have been encrypted. Before you go straight to them, though, let us first tell you a few more words about this Ransomware.

How do the like .Roldat cryptoviruses work?

The Ransomware cryptoviruses ( like .Roldat, .Todarius , .Kiratos, .Verasto ) sneak inside the victim’s system in various ways. They start scanning the computer’s disks for certain types of files, for example, documents, pictures, video and audio materials, etc. Next, they begin to copy these files, applying to them the copies a unique encryption code that no program is able to crack. As a result, the copies of the files end up with a different extension and you are not able to open them until you apply a special decryption key. In the end, the original files are removed and this is where the real blackmailing begins – the criminals controlling the invasive Ransomware demand a ransom in exchange for the decryption key which is typically stored on their servers. As soon as the encryption process is over, they place a ransom notification on the screen of the victims and ask them to transfer a certain amount of money to a given cryptocurrency wallet. Unfortunately, nobody can tell you what will happen if you transfer the money. Needless to say, there’s nothing stopping the blackmailers from keeping the key to themselves instead of sending it to you. They may even ask for another payment with even higher ransom amount or send you another malware piece instead of a decryption solution. Therefore, the security experts advise against sending them your money. Of course, we cannot tell you what to do and how to act but what we can do is tell you how things really are and inform you about the options that you can choose from. If you want to continue to use your computer, however, it is necessary to remove .Roldat. This way, you will have a clean system and will be able to create and save new files in it without them getting encrypted. In case you don’t know how to do that, there are detailed instructions below, as well as a trusted removal tool for automatic assistance and a section with some file-recovery suggestions.
