The Nols Virus Impact on an Infected PC
The name Nols files virus is given to a data locker ransomware which is based on the code of the popular STOP ransomware. Once the threat drops an executable file on the system it finds a way to start it so that the file can trigger a sophisticated infection process. Then the ransomware becomes able to pass through several attack stages. This type of malware is primarily designed to locate valuable personal files stored on the infected PCs and encrypt them with a strong cipher algorithm. It is known that the Nols virus uses the AES algorithm to encrypt target data. That’s why all target files remain inaccessible after corruption. In addition, their names appear with the suffix .nols in their names. As a result of data corruption, the Nols ransomware extorts a ransom fee for decryption. For this stage, it drops a ransom message and loads it on the screen.

It is also possible for the document to be added to a ZIP archive file. Once the file is started on the PC, it may ask you to enable macros which will start the Nols infection. The document may also be designed to display a system notification that misleads victims to click the “OK” button in order to open the content of the file.
Another commonly used trick of ransomware and malware dissemination is a spoofed link that redirects to a crafted web page that can automatically download the payloads on the PC. The sender itself may impersonate well-known companies and services. However, malicious traits can be revealed almost always. Online scanning services like ZipeZip (free online archive extractor and malware scanner) and VirusTotal (a free service that analyzes suspicious files and URLs) can help the detection of potential malware infections.

These are some common folder locations where Nols virus may be hiding malicious files and objects:
The main goal of Nols ransomware is to become able to activate a specific module that encrypts target files by utilizing sophisticated cipher algorithms like AES, RSA, and Salsa20. At the end of the encryption process, the ransomware appends an extension of the same name to files names – .nols
Unfortunately, since all of the following types of files are often used for the storage of important data, they are likely to be corrupted by Nols STOP ransomware:
At the end of the attack, Nols virus ransomware drops ransom note file named _readme.txt to extort a ransom fee for .nols files recovery. When opened that file may state the following:
