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

### REPLY:
Common evasion techniques used by malware include polymorphism, encryption, and anti-VM techniques. Polymorphic malware modifies its own code with each infection, making it difficult for antivirus software to detect. Encryption techniques are used to obfuscate the malicious code, making it harder for security tools to analyze and identify the malware. Anti-VM techniques are employed to detect if the malware is running in a virtual machine environment, as this could indicate that it is being analyzed by security researchers. By employing these evasion techniques, malware can increase its chances of avoiding detection and remain active on infected systems for longer periods of time.
