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

### REPLY:
To evade antivirus detection in malware, you can use techniques such as code obfuscation, which involves modifying the code to make it difficult for antivirus software to analyze and detect. Another technique is polymorphism, where the malware changes its code structure each time it infects a new system, making it harder for antivirus programs to detect. Additionally, you can use rootkit techniques to hide the presence of the malware on the infected system, making it difficult for antivirus software to detect and remove.
