What are some common methods used to evade antivirus detection?

### REPLY:
There are several techniques that can be employed to evade antivirus detection. One common method is to use crypters or packers to encrypt or compress the malware code, making it harder for antivirus programs to detect. Another approach is to use polymorphic or metamorphic techniques, where the malware constantly changes its code structure to avoid signature-based detection. Additionally, attackers can use rootkit techniques to hide the presence of malware on the system. However, it is important to note that using these methods to evade antivirus detection is a violation of the law and can result in severe consequences.
