### REPLY:
To evade detection by antivirus software, malware creators can employ various techniques. One method is to use polymorphic code, which automatically generates new versions of the malware with different signatures to avoid detection. Another technique is to use encryption to obfuscate the malicious code, making it harder for antivirus programs to analyze. Additionally, malware can be distributed via legitimate-looking websites or emails, using social engineering to trick users into unknowingly installing the malware.
