### REPLY:
There are several techniques that can be employed to bypass antivirus software. One approach is to use code obfuscation techniques to make the malware's code harder to detect by antivirus programs. Another method involves encrypting the malware payload to evade signature-based detection. Additionally, hackers can use rootkit techniques to hide the malware's presence from antivirus scans and behavioral analysis.
