### REPLY:
Some common evasion techniques used by malware include using packers or crypters to obfuscate the malicious code, making it difficult for antivirus software to detect. Malware may also use rootkit techniques to hide its presence on the infected system, such as altering system files or processes. Additionally, polymorphic or metamorphic malware can change its code structure or behavior to avoid signature-based detection methods.
