1. How does the NPSK ransomware virus infect your computer?
Cybercriminals use various techniques to introduce viruses into target computers. Ransomware can infiltrate a victim's computer in several ways. In most cases, ransomware attacks are carried out with the help of the following methods:
- Spam : This is the most commonly used method. Cybercriminals use phishing emails disguised as legitimate business organizations or companies (receipts, prize notifications, order confirmations, bank messages, etc.) to trick users into clicking on malicious attachments.
- Software : Hackers use specialized tools to exploit known vulnerabilities in systems or applications. That's why you should always update Windows to the latest version.
- Suspicious web sources : Various suspicious websites may contain malicious scripts or hyperlinks that could infect your system.
- Remote Desktop Protocol: Cybercriminals often abuse the built-in Windows Remote Desktop Protocol feature to infect computers with ransomware. This allows them to remotely access the target computer and manually install the virus.

3.1. Recovering files with recovery tools
In the event your computer is attacked by ransomware, you may need to recover your files using data recovery software. Stellar Data Recovery is one of the most effective tools that can recover lost or corrupted files such as documents, emails, photos, videos, audio files, and more on any Windows device. Its powerful scanning engine can detect compromised files and ultimately save them to a designated location.
- Open Stellar Data Recovery.
- Select the file types you want to recover and click Next .
- Select the drive and folder where your files are located and the date you want to recover them. Then press Scan .
- After the scanning process is complete, click on Recover to restore your files.
Next, choose where you want to save the file and click Start Saving to save the recovered data.
Because new ransomware viruses emerge almost daily, there's no technical capability to release a decryption tool for every single one. In this case, recovery tools have a chance to prove their effectiveness. While this is one of the most effective methods when a decryption tool isn't available, it's not 100% guaranteed and isn't the only way.
3.2. Restoring the system using System Restore
Although the latest version of the Npsk ransomware can delete system recovery files, this method may help you recover some of your files. Try this method and use the standard System Restore tool to recover your data. The entire process is best performed in Safe Mode with Command Prompt .
*For Windows XP/Vista/7 users:
Restart your computer before the system starts by pressing the F8 key several times. This will prevent the system from loading and will display the Advanced Boot Options screen . Select Safe mode with Command from the list of options using the up and down arrow keys on your keyboard and press Enter .
*For Windows 8/10 users:
- Click the Start button and select Settings .
- Click on Update & Security , then select Recovery > Restart now .
- After your device restarts, click Troubleshoot > Advanced options > Startup Settings > Restart .
Press the F5 key to enable Safe Mode with Command Prompt .
After the system has loaded into Safe Mode with Command Prompt, follow these steps:
Step 1: In the Command Prompt window, type cd restore and press Enter .
Step 2: Then type rstrui.exe and press Enter again.
Step 3: In the new window that appears, click Next .
Step 4: Select the date and click Next again.
Step 5 : Click Yes to begin system recovery.
3.3. Restoring a previous file version
Previous versions may be copies of files or folders created by Windows Backup (if it works), or copies of files and folders created by System Restore. You can use this feature to recover files and folders that you accidentally modified, deleted, or corrupted. This feature is available in Windows 7 and later versions.
Here's what you do:
- Right-click on the encrypted file and select Properties.
