How to Allow or Whitelist noVNC in Your Antivirus Software

If you're having trouble using noVNC, it could be that your antivirus software is blocking it. Many antivirus programs flag certain applications as potential threats, even if they are perfectly safe. This guide will walk you through the steps to allow or whitelist noVNC in your antivirus software so you can access it without any issues.

Why is noVNC Being Blocked?

Antivirus software works to protect your computer from potential threats by scanning programs for malicious activity. Occasionally, noVNC’s network behavior or the way it interacts with your system can be misinterpreted as suspicious, causing the antivirus to block it.

In most cases, noVNC is completely safe, but to avoid this issue, you may need to whitelist it within your antivirus settings.
