What is Nyetya Ransomware capable of?

The viruses from the Ransomware type are usually used to encrypt files and stop you from accessing them. They do that with the help of a very special secret file encryption and a tricky blackmail scheme. Basically, what malware like Nyetya does is it converts your documents, images, archives, work projects and other types of data into completely unreadable files, so that you cannot open or use them with any program unless you pay for their decryption. The hackers, who control the Ransomware, usually ask their victims for ransom in exchange for a special decryption key, which can bring the affected files back to normal. This kind of contamination is really among the most horrifying forms of online blackmail and regardless whether you decide to pay the demanded ransom or not, recovering from the attack may not be fully possible.

Here is how the typical infection usually happens.

File-encrypting viruses like Nyetya are special pieces of software, programmed to secretly infiltrate your PC and access all your disks and data storage. Once they get inside the system, the next activity they usually perform is to create a detailed list with all the data found on your drives. After that action is completed, the real encryption process is launched and all of the enlisted files get encoded with a very strong and complex algorithm one by one. The next stage after all the data is rendered inaccessible is the generation of a ransom-demanding message that is, in fact, the only indication of the infection. This message lets you know about the completion of this terrible process and usually asks you to pay certain among of money (in Bitcoins) for the decryption key of your files. Without a doubt, this Ransomware is definitely the most awful infection you can ever face, as well as one of the hardest to counteract and remove. Nonetheless, our “How to remove” team will do our best to help you deal with it in the best possible way.

Nyetya Ransomware Virus Removal



Restoring basic Windows functionality
Before you are able to remove the Petya.a  Virus from your computer you need to be able to access it in the first place. Since the ransomware will prevent Windows from booting itself your first job is to repair the Master Boot Records (MBR) of your drive.
To do that you’ll need your original Windows OS DVD (or an USB bootable drive for advanced users)
  1. Insert the DVD (or the USB) into the computer, then run the computer and choose to boot the OS from the DVD/USB. You may have to change Windows boot priorities from the bios by pressing Del
  2. When Windows boots from the DVD/USB select Windows Repair
  3. Open the Command Prompt and write the following commands inside:     enter: bootrec / fixmbr, bootrec / fixboot and bootrec / rebuildbcd
  4. Your Windows OS should now be able to boot normally. You can proceed with the removal of the virus as usual.

Potential sources of the Nyetya infection:

Unfortunately, there is very little you can do to fully protect yourself from a Ransomware threat like this. This type of malware frequently infects people through contaminated emails, malicious attachments, spam messages or other almost legitimate-looking transmitters. Basically, any email, ad, pop-up or a link that you receive may eventually contain a Ransomware threat. That’s why it is a good idea to stay way from content you don’t trust. Don’t get tempted to click on everything that appears on your screen or your email and avoid installing torrents, setups or archives that don’t come from reputed developers. A very common malware distributor is the Trojan horse. Many hackers with malicious intentions frequently use it to deliver Ransomware inside the users’ system by silently inserting it without any visible symptoms. Also, different fake ads, misleading links, and pop-ups may also be used to introduce such malware inside the computer without much of indication. However, as tricky as it is, you can at least try to make sure you won’t catch such a Ransomware infection by simply staying away from its main sources. 

Are there any possible solutions that can help you combat the effects of Nyetya?

Most of the victims of Ransomware usually make a quite impulsive decision by agreeing to pay the required ransom with the hope to save their files. However, the security experts advise that in a case of a Ransomware attack one should not act out of fear and should always look for alternative solutions to remove the malicious infection. What we can offer you here is to try some of the tools and removal guides that are available on the web. If you would like to remove this virus, you can try the instructions in the removal guide below.
