This page aims to help you remove .Nesa for free. Our instructions also cover how any .Nesa file can be recovered.


.Nesa is a recently released Ransomware virus of the cryptovirus subtype. The main purpose of .Nesa is to extort money from its victims by means of locking their files, and demanding a ransom for the files’ release.

You have likely already heard about this category of dangerous programs, as they are currently a very widespread threat on the Internet. However, it is one thing to have heard about Ransomware, and a whole other thing to get one such virus in your computer. If .Nesa is inside of your system at the current moment, you really need to find a way to stay calm. We understand that you are probably frustrated by your inability to open any of your important files, and we know just how unpleasant and problematic this might be. However, if you act out of impulse right now, you may make things even worse for yourself. Therefore, allow us to familiarize with the options you have right now, so that you can choose the best one for your particular situation.

The .Nesa virus

The .Nesa virus is a malware tool that some hackers use to get your money. Paying the ransom demanded by the .Nesa virus, however, could lead to more issues, instead of solving anything.

Though to many of you it may seem like a necessary trade off that will allow you to restore your files, the payment of the ransom may oftentimes not improve your situation in any way, and only worsen it. This is because you have no way of knowing what would happen if you pay the money – you don’t know if you’d get the decryption key of your files, or if the key you get would get the job done. And, indeed, many are the users who have had to learn this the hard way – by paying the demanded sum, and still not getting to restore their files. This is what may happen to you as well if you pay the hackers, which is why we advise you to refrain for opting for that action unless you really have no other choice, and only if the inaccessible files are worth the risk.

The .Nesa file encryption

The .Nesa file encryption is what is keeping your files inaccessible. To deal with the .Nesa file encryption without paying the ransom, there are a couple of things that can be tried.

Remember, however, that without the decryption key that corresponds to the encryption, you may be unable to restore any piece of encrypted data no matter what you try. That being said, you should still definitely give a try to the options available to you. A number of them have been compiled in the second section of the following guide, but before you make any attempt to restore your files with their help, you should first ensure that the Ransomware is gone from your computer. Only then can you safely try to bring any of your data back, as there wouldn’t be a cryptovirus in your computer to lock it once again, and render your efforts pointless.

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:
