How can malware evade detection by antivirus software?

### REPLY:
To evade detection by antivirus software, malware can use advanced rootkit techniques to hide its presence on the infected system. This includes modifying system files, disabling security features, and even intercepting API calls to manipulate the behavior of the operating system. Additionally, some malware may exploit vulnerabilities in antivirus software itself to disable or bypass its detection mechanisms.
