What type of antivirus software is designed to work seamlessly without any user intervention?

Real-time antivirus software is designed to actively monitor and protect a system from malware threats continuously and automatically without requiring user intervention. It works in the background, scanning files in real-time as they are opened, executed, or downloaded. This immediacy helps to prevent infections before they can spread or cause damage, making it an essential tool for maintaining security on devices.

In contrast, on-demand antivirus requires manual action from the user to initiate scans and evaluate the system for threats. Behavioral-based antivirus focuses on detecting behavior patterns of applications to identify potential threats, which still may involve user action to respond to reported anomalies. Signature-based antivirus relies on a database of known malware signatures to identify threats, typically functioning as a component of real-time protection rather than as a standalone solution. Real-time antivirus combines the principles of both behavioral and signature-based detection while automating the entire process for better user convenience and security.
