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

### REPLY:
One common technique used by malware to evade detection is to exploit vulnerabilities in antivirus software itself. By targeting these vulnerabilities, the malware can disable or bypass the antivirus software, allowing it to operate undetected. Another technique is to use steganography to hide the malicious code within seemingly harmless files, such as images or documents. This makes it difficult for antivirus software to identify and remove the malware.
