### REPLY:
Some common methods for bypassing antivirus software include using packers or crypters to encrypt the malware code, employing rootkit techniques to hide the malicious files or processes from detection, and using polymorphic or metamorphic techniques to constantly change the malware's signature and evade detection by antivirus programs. Additionally, attackers can use sandbox evasion techniques, such as checking for virtual environments or delaying the execution of malicious actions, to avoid triggering antivirus alerts.
