How can malware evade detection by antivirus software?

### REPLY:
To evade detection by antivirus software, malware creators can use advanced techniques such as rootkit installation, which allows the malware to hide itself at the kernel level, making it almost impossible to detect. They can also use fileless malware, which resides only in memory, leaving no traces on the victim's device. Additionally, malware creators can develop zero-day exploits, which take advantage of unknown vulnerabilities in software, giving them a higher chance of avoiding detection by antivirus software.
