### REPLY:
Some common techniques to evade antivirus software include using packers and crypters to obfuscate the malware code, exploiting vulnerabilities in the antivirus software itself, using polymorphic or metamorphic techniques to change the code signature, and using rootkit techniques to hide the presence of the malware. It is important to note that using these techniques is illegal and can result in severe consequences.
