How to remove Domn virus and restore encrypted files

Guide how to delete Domn virus and decrypt files corrupted by ransomware. Effective antivirus and programs that can restore lost information.


Encryption virus can be considered a bogey of a recent society, and each PC operator knows that if you can not open the information and you see a ransom note – the things are going ugly. It’s a correct reaction, unfortunately. Domn threat is the ugliest thing that might happen to you on the Internet because a regular user literally cannot delete it. The only situation when you can overcome ransomware is if you are not facing a true virus, but a phoney, that covers the screen and tries to lure your money. In all other events, if a virus was created and protected in a right way – you should only trust that specialists can beat it. If swindlers committed a mistake, and a ransomware has any flaws, which give you an ability to get back files – we’ll explain to you what to do in this item.



Bypassing the ransomware’s type, the AES and RSA methods are very complex to bruteforce them. It can take centuries to execute all required calculations on a standard home PC or, possibly, 3-4 decades in case of usage of an industrial gear. We know only two efficient ways to defeat an encrypting malware: to find vulnerabilities in its code, or break into its database, to receive encryption keys. In rare cases there is a switch, able to stop virus' operation completely or to leave unscathed a particular computer. If someone finds such switch for this virus, or create a decryption program, we will update this item.


What we have to say about ransomware? It is founded on a completely legitimate encryption system that modifies the folders on operator’s computer and makes them useless without a key. Of course, a key is also encoded with a different algorithm. Usually, these manners are AES and RSA, that are famous for their complicacy and fail-safety. The mentioned manners and the tools built upon them can be easily found in the Net, so scammers just need to develop protective techniques, to restrict an inlet to a program, and create the reliable update and control scheme. Some viruses may function off-line, and web-criminals know about a new victim only when he contacts them and sets off his money. The best viruses are function in different manner, and send reports to hundreds URL's, to puzzle the security specialists and throw them off virus’ track.


Here you can find some methods to examine, before yielding and waiting for a decryption tool. As it is stated in previous paragraphs, Internet-criminals make errors, and certain characteristics of the Windows can serve you to restore data.


  • If you don't employ the Windows through an admin profile – today’s your happy day. The thing is that your OS replicates all data before they’re eliminated or modified. These backups are known as the SVC, and Domn knows how to delete them. If you're employing the usual profile – the operating system requests for a authorization at the exact moment Domn starts to remove SVC. If you saw such request and reversed it – your copies are fine, and might be used to recover the files.
  • A protected copy is the single fully productive way to recover the information, but you should eliminate Domn first. Ensure that the malware is deleted totally, as if it’s not – all information will be encrypted again, including those that were stored on a flash drive.


If all of written above hints didn't work and you have no chance to restore your data – you need to eliminate the malware from the device and expect when a decryptor will be developed.

How to remove Domn

Unfortunately, there’s no possibility to totally elude an installation of software. The virus is too sly and there is a chance pass some parts and then regret it (for example, when you connect an external drive with the saved information to a not-really-cleared system). It knows how to lurk pretty well, so you just can't delete it completely with your own hands. Knowing this, we’ve made a solid deletion instruction that will suit all your needs. It consists of some manual stages and one extra AV tool stage.
