The Nwgen virus falls under the ransomware type of malicious agent. Harmful software of this type encrypts all the data on your PC (images, text files, excel sheets, audio files, videos, etc) and adds its extra extension to every file, leaving the How To Restore Your Files.txt files in each folder with the encrypted files.
What is Nwgen?
☝️ A strictly correct description for the Nwgen is “a ransomware infection”.
Nwgen adds its extra .nwgen extension to the name of each encoded file. For example, an image named “photo.jpg” will be turned into “photo.jpg.nwgen”. Just like the Excel sheet with the name “table.xlsx” will be altered to “table.xlsx.nwgen”, and so on.
In every folder containing the encrypted files, a How To Restore Your Files.txt text document will appear. It is a ransom money note. Therein you can find information about the ways of contacting the racketeers and some other information. The ransom note most probably contains a description of how to buy the decryption tool from the racketeers. That is how they do it.

In the image below, you can see what a directory with files encrypted by the Nwgen looks like. Each filename has the “.nwgen” extension appended to it.
How did my computer get infected with Nwgen ransomware?
There are many possible ways of ransomware infiltration.
Nowadays, there are three most exploited methods for malefactors to have the Nwgen virus acting in your system. These are email spam, Trojan introduction and peer-to-peer file transfer.
If you access your mailbox and see letters that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose sender is unknown to you, be wary of opening those letters. They are very likely to have a harmful item attached to them. So it is even more dangerous to download any attachments that come with emails like these.
As for the peer networks like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. So you’d better be using trustworthy resources. Also, it is a good idea to scan the directory containing the downloaded objects with the anti-malware utility as soon as the downloading is done.
How to remove the Nwgen virus?
It is crucial to inform you that besides encrypting your data, the Nwgen virus will probably install the Azorult Spyware on your computer to get access to credentials to various accounts (including cryptocurrency wallets). That spyware2 can extract your logins and passwords from your browser’s auto-filling cardfile.
Sometimes racketeers would decrypt several of your files so you know that they really have the decryption tool. Since Nwgen virus is a relatively new ransomware, security software developers have not yet found a method to undo its work. Nevertheless, the decryption tools are constantly upgraded, so the solution may soon arrive.
Understandably, if the criminals succeed in encrypting victim’s essential files, the desperate person will most likely comply with their demands. Despite that, paying a ransom gives no guarantee that you’re getting your files back. It is still risky. After getting the money, the racketeers may send a wrong decryption key to the victim. There were reports of hackers simply disappearing after getting the money without even writing back.
The optimal safety measure against ransomware is to have aan OS restore point or the copies of your critical files in the cloud storage or at least on an external disk. Obviously, that might be insufficient. Your most crucial thing could be that file you were working upon when it all went down. But at least it is something. It is also reasonable to scan your drives with the antivirus program after the OS restoration.
Nwgen is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Bbbw, Maiv, Cuag, and some others. The two major differences between them and the Nwgen are the ransom amount and the method of encryption. The rest is the same: documents become inaccessible, their extensions altered, ransom notes are found in every directory containing encrypted files.
Some lucky people were able to decrypt the arrested files with the aid of the free software provided by anti-malware experts. Sometimes the racketeers accidentally send the decryption key to the victims in the ransom readme. Such an epic fail allows the user to restore the files. But of course, one should never rely on such a chance. Make no mistake, ransomware is a criminals’ technology to lay their hands on the money of their victims.
How to avert ransomware infection?
Nwgen ransomware has no endless power, so as any similar malware.
You can armour your system from ransomware injection within several easy steps:
- Ignore any letters from unknown senders with unknown addresses, or with content that has likely no connection to something you are expecting (how can you win in a lottery without participating in it?). If the email subject is more or less something you are waiting for, check all elements of the suspicious letter with caution. A fake letter will surely have mistakes.
- Do not use cracked or unknown programs. Trojan viruses are often shared as an element of cracked software, most likely as a “patch” which prevents the license check. Understandably, potentially dangerous programs are difficult to tell from trustworthy ones, as trojans sometimes have the functionality you seek. Try searching for information about this program on the anti-malware forums, but the best way is not to use such software.

Frequently Asked Questions
🤔 How can I open “.nwgen” files?Is it possible to open“.nwgen” files?
Unfortunately, no. You need to decipher the “.nwgen” files first. Then you will be able to open them.
🤔 The encrypted files are very important to me. How can I decrypt them quickly?
Hopefully, you have made a copy of those important files. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. All other solutions require time.
🤔 What to do if the Nwgen ransomware has blocked my PC and I can’t get the activation code.
🤔 And what should I do now?
Many of the encrypted files might still be at your disposal
