XWorm is a multi-functional malware family, commonly used as remote access trojan. It allows cybercriminals to gain unauthorized access to devices, steal sensitive information such as login credentials and passwords, or even install ransomware and launch DDoS attacks. This modular design makes XWorm a sophisticated and highly customizable piece of malware.

Possible symptoms

XWorm is designed to operate discreetly, but these signs might give it away:

  • Unexpected system slowdown.
  • A sudden increase in network traffic.
  • Suspicious remote connections to your computer.
  • Changes in system settings.
  • Unfamiliar files or programs appearing on your computer.

Sources of infection

Phishing emails with malicious Word, Excel, or PDF files, drive-by downloads (unintentional downloads) from infected websites, and malvertising are the main sources of XWorm infection.


Always stay vigilant online to protect yourself from XWorm and similar cyber threats.

  • Be cautious with email attachments, especially from unknown senders.

  • Use NordVPN’s Threat Protection to scan downloads for malware, block harmful websites, and avoid malicious ads.

  • Install reputable antivirus software and keep it updated.

  • Enable multi-factor authentication (MFA) for extra protection against unauthorized access.

  • Regularly back up important data.


You can use antivirus software to remove XWorm, but keep in mind that such tools are more efficient in preventing the infection than removing it.

  • Disconnect the infected device from the internet and your network.
  • Run a full system scan using a reliable antivirus software and follow your software’s instructions to remove XWorm from your device.
  • If you’re not sure about complete removal, consult an IT specialist.
