A Ransomware is definitely not something you’d want to have on your computer. This is a form of malware responsible for the locking-up of the users’ files present in the attacked system. The process which allows a Ransomware to lock up your files is called data encryption and it is actually not a process that is malicious by design. Data encryption is actually a method of protecting sensitive and important files – an encrypted file cannot be accessed or modified unless the corresponding decryption key is used. Of course, the useful nature of the data-encryption procedure is turned on its head when used by a Ransomware. You have probably already guessed what the difference is when encryption is used by a Ransomware threat – the decryption key is initially only available to the cyber criminals who are behind the creation of the virus.
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.
