Can you explain the concept of polymorphic malware?

### REPLY:
Polymorphic malware is a sophisticated type of malware that can change its code and behavior dynamically, making it extremely difficult for antivirus software to detect and remove. It achieves this by using encryption, code obfuscation, and randomization techniques. By continuously changing its appearance, the malware can evade detection and stay undetected on infected systems, allowing attackers to carry out their malicious activities.
