What does Polymorphic refers to a malware's ability to do?

Polymorphic malware refers to its capability to change its code or signature each time it infects a new system, making it difficult for antivirus software to detect it. This adaptability allows the malware to evade detection by altering its appearance while maintaining its underlying functionality. By continuously modifying itself, polymorphic malware can persist in systems and spread without being easily recognized or removed.
