What are some common techniques used by malware to evade detection by antivirus software?

### REPLY:
One effective technique used by malware to evade detection by antivirus software is to exploit vulnerabilities in the antivirus software itself. By exploiting these vulnerabilities, the malware can disable or bypass the antivirus software, allowing it to operate undetected. Additionally, malware can use sophisticated encryption techniques to encrypt its code, making it nearly impossible for antivirus software to analyze and detect the malicious behavior.
