How can malware evade detection by antivirus software?

### REPLY:
Malware can evade detection by antivirus software through various means. One technique is to use polymorphic code, which continuously modifies its own structure to create unique variants that are difficult for antivirus programs to detect. Another method involves encrypting the malware's code or using packers to compress and obfuscate it, making it harder for antivirus software to analyze. Attackers can also use rootkit techniques to hide the presence of malware within the operating system, bypassing traditional detection methods. However, it is important to remember that engaging in such activities is illegal and can have severe consequences.
