What are some common methods to evade detection by antivirus software?

### REPLY:
There are several techniques to evade detection by antivirus software. One method is to use a crypter, which encrypts the malware code to make it undetectable by antivirus signatures. Another technique is to use code obfuscation, which alters the malware code to make it more difficult to analyze and detect. Additionally, polymorphic malware can change its code structure dynamically to avoid detection. It is important to stay updated with the latest antivirus software and security measures to protect against such evasive techniques.
