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

### REPLY:
One effective technique to evade detection by antivirus software is to exploit zero-day vulnerabilities in the operating system or the antivirus software itself. By leveraging these vulnerabilities, the malware can bypass security measures and remain undetected. Additionally, malware can use social engineering tactics to trick users into disabling or uninstalling their antivirus software, leaving the system vulnerable to infection.
