### REPLY:
One common technique used by malware to evade detection is to exploit vulnerabilities in antivirus software itself. By targeting known weaknesses or flaws in the antivirus program, malware can bypass or disable the security measures in place, allowing it to operate undetected. Additionally, malware can also use rootkit techniques to hide its presence on the infected system and manipulate the behavior of the antivirus software, making it ineffective in detecting the malware.
