The new .Kovasoh virus

 Kovasoh is a cryptovirus infection that works in this exact way – it uses its advanced data encryption to render the files of its targets inaccessible and then it shows a notification banner on the computer screen. Through the message in this banner, the user learns that their files have been locked by a Ransomware and that they would need to pay money to the hackers if they are to acquire the decryption key corresponding to the encryption code. Many users pay the demanded ransom immediately after they read the ransom message. However, a lot of people can’t afford to spend a couple of hundred, or even a couple of thousand dollars by sending them to some online criminals. Also, and this should go without saying, there isn’t any conceivable way of actually knowing whether or not the hackers would enable you to restore the access to your data by sending you the corresponding decryption key – for all you know, they may simply be lying to you. And of course, should you still send your money to the criminals behind an infection such as Kovasoh,  Cosakos, Nvetud you’d never get the chance to get that money back from the hackers. Even if you don’t get to unlock your files after the payment, there wouldn’t be a refund.

The .Kovasoh file encryption – options?

If you have decided that you will still pay despite the warnings we’ve just given you, it is your decision and you are the only one who knows your specific situation. However, if you choose to put aside the payment option and instead focus on some of the potential alternatives, we may have something for you here.

 No matter what happens with your files, it’s still important to remove Kovasoh, and the Kovasoh removal guide below will hopefully allow you to do exactly that. And after you are done eliminating the nasty Ransomware, you can try some of the potential file recovery options we have on our site. Sadly, we can’t guarantee that any of them will enable you to release all of your data from Kovasoh. Still, they are a good place to start and it won’t cost you a penny to give them a try.

Ransomware cryptoviruses such as Cosakos are some of the most dangerous computer infections that you can encounter online. Dealing with them can be very challenging, yet, there is no need to let the panic take you over. The main problem with the Ransomware-based infections is the fact that they don’t harm anything on the system and, thus, the security programs rarely can detect them. Unlike most other computer threats, such as Trojans or Rootkits who usually do some significant damage, these pieces of malware just apply a special encryption to the files, stored in the system without damaging them. In this way, infections like Cosakos, Nvetud or Mogranos prevent the victims from accessing their information and ask them to pay a ransom (usually in BitCoins) in order to regain their access. Another factor that plays a great role when it comes to surprising the victims is the stealthiness of the Ransomware. Such malware can sneak inside the system with the help of many infection methods, including through the distribution of spam, malicious email attachments, fake software update requests, infected ads and more. On top of that, in many cases, it may not be possible to reverse the effects of their attack successfully.

To access the encrypted information, you would need to apply a special decryption key, which can reverse the applied encryption. This key, however, is kept at the server of the attackers who stay behind the Ransomware and they will ask you to pay a certain amount of money for it. They will display a ransom-demanding notification on your screen with instructions on how to make the payment.

Professional malware researchers all around the web, who try to combat Ransomware infections, advise the victims of this blackmailing software not to give their money to the hackers. The strongest reason for that is the fact that the online crooks simply cannot be trusted. They may easily trick you into paying the ransom by promising that they will help you get your files back and then simply disappear without sending you nothing. Even if you follow every step of their ransom-payment instructions, there is no guarantee that you will get the decryption key. Not to mention that, in the event you do get one, there is no proof that it will work. The only thing that is for sure is that your money will be gone and there will be no refund, regardless of whether you get your data back or not.

Can the .Cosakos file encryption be broken?

In case your audios, videos, images, documents and other personal files have been encrypted by Cosakos, our suggestion is to take a look at the Removal Guide below. It contains instructions on how to remove the Ransomware both manually or with the help of a professional removal tool, as well as some file-recovery suggestions. If you have backups, you can use them as well. Keep in mind though, that the effectiveness of the alternative methods may vary from case to case. Therefore, a 100% success in file-recovery cannot be guaranteed in all the cases.

 Nvetud is a recent and very unpleasant example of a Ransomware cryptovirus – it was recently reported by users who have suddenly realized that none of their personal files stored in their computers’ hard drives can be opened. Of course, the hackers behind Nvetud or Cosacos readily offer a “solution” – pay them some money and you will get all of your files back. This is, after all, the main purpose of the Ransomware threats, and also the reason why these pieces of malware are named that way.The sole goal of the hackers behind Ransomware is to acquire money from their victims through blackmailing. However, many users may not be able or willing to pay, and may be more interested in finding alternative solutions to such an issue. Also, if you are one of the people who may be considering making the payment, we advise you to stay with us until the end of this post to learn why this isn’t really a very good idea.

The ransom demanded by the .Nvetud virus

It is usually not advisable to opt for this – even if you have the money available and are ready to send them in order to restore your data, you shouldn’t go ahead and do that without trying anything that doesn’t involve sponsoring some Internet criminals. The main problem with the ransom payment is the uncertainty surrounding the decryption key that the hackers promised. Does such a key even exist, and will it really be sent to you is something you simply can’t be sure about. The only sure thing is that if you send your money, that money would be gone for good and even if you don’t get your data back after the payment, you cannot hope for a refund.

Alternative ways to handle the .Nvetud file encryption

First, you will need to remove the malware from your computer, and the guide you will find on this page will help you do that. In case you need extra assistance with the removal, we recommend the anti-malware tool that is linked in the guide.

 After Nvetud is gone, you can go to the second part of the guide and take a look at the potential recovery methods posted there – they may not always work and be fully effective but trying them out is still preferable to risking your money by sending it to the hackers who are blackmailing you.
