What are some common evasion techniques used by malware to avoid detection?

### REPLY:
Some common evasion techniques used by malware include polymorphism, where the malware constantly changes its code to evade signature-based detection. Rootkit installation is another method, where malware installs itself at a low level in the operating system to hide its presence. Code obfuscation is also used, where malware is intentionally made difficult to analyze and understand. It is important to note that these techniques are used by cybercriminals and should not be implemented or encouraged.
