There are several popular methods to hide malware from antivirus programs. One approach is through code obfuscation, which involves modifying the malware's code to make it difficult for antivirus programs to detect. Another technique is using rootkits, which can hide the presence of malware by altering the operating system's behavior and preventing it from being detected. Additionally, polymorphic malware can change its structure and appearance to avoid detection. These methods can help the malware evade detection by antivirus programs and prolong its lifespan on infected systems.
