Remove .Nols Virus File Ransomware (+Recovery)



.Nols is malware of the Ransomware subset. .Nols makes the files in the attacked computer inaccessible and demands a cryptocurrency ransom payment for their release.

The .Nols Virus will stealthily encrypt your files and when it is done it will leave a _readme.txt file.

The malicious .Nols virus will not let you open your files until you pay the ransom that its creators demand from you. This is how most Ransomware threats typically operate. Not all forms of Ransomware lock the user’s files – some block the screen of the computer by superimposing a big banner on it, while others steal the data of their targets, and threaten to release them on the Internet. In all cases, however, the goal remains the same – to force the victim to pay money, hence the name Ransomware.

The .Nols virus

The .Nols virus is damaging computer software categorized as Ransomware. The .Nols virus is able to make its victimsdata inaccessible, and then blackmail them for a ransom payment.

The cryptovirus subcategory of Ransomware is the worst of them all, and .Nols is one of its newest representatives. As we said, if .Nols is in your machine, you are probably unable to open most of your personal data files. What causes this is the encryption that this Ransomware places on them, and the worst part about it is that the encryption is bound to stay on the files even once you manage to get rid of the infection responsible for it. That being said, you must still make sure to remove this piece of malware. Otherwise, new files that you download or create in your system may get encrypted as well, worsening the situation. Therefore, it is highly important that you go to the guide below this article once you are finished reading here and follow its steps, as that should allow you to eradicate the Ransomware. After the threat is gone, you can focus on file recovery.

The .Nols file extension

The .Nols file extension replaces the original extensions of your files. The new extension added by .Nols prevents the affected files from being opened by any software. 

Another very unpleasant trait of this type of computer infections is that there isn’t a universal data recovery solution that can help you set your data free in every case. Even a high quality anti-malware tool such as the one from the current page cannot help you with the actual recovery of the files – it can only remove the virus for you. This leaves you with a difficult choice – you can either pay the ransom if you have the requested money readily available to you, or you can try other methods that may or may not be effective depending on the specific case. What you should understand here, however, is that the ransom payment also doesn’t guarantee the recovery of the data. The hackers may simply refuse to keep the promise they’ve made about releasing your files from the encryption’s grasp once they have your money. That is why the payment isn’t really your best option.

Our suggestion for you is this: remove the Ransomware using our guidelines from below, and then visit the second section of the guide where you will find several potential solutions that are alternatives to the ransom payment. Though they might not work for all Ransomware victims, they are still worth the try as it won’t cost you anything to complete them, and they may potentially help you bring back some of the files. In case you need extra assistance, you can always contact us directly via the comments section.
