There are several techniques that can be used to hide malware from antivirus software. One method is to use code obfuscation, which involves modifying the malware's code to make it more difficult for antivirus programs to detect. Another technique is encryption, where the malware's code is encrypted and decrypted at runtime to evade detection. Additionally, attackers can also use rootkit techniques to hide the presence of malware by modifying the operating system's core components. It is important to note that using these techniques is illegal and can lead to serious legal consequences.
