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

### REPLY:
Malware often employs various evasion techniques to avoid detection by antivirus software. These can include polymorphic code, which generates unique variants of the malware to bypass signature-based detection, or packing the malware with encryption and obfuscation techniques to make it harder for security tools to analyze the code. Additionally, malware may employ anti-emulation techniques to detect if it is running in a virtual machine or sandbox environment, allowing it to remain dormant and undetected.
