One common technique used by malware to evade detection by antivirus software is to encrypt the malicious code using advanced encryption algorithms. This makes it extremely difficult for antivirus programs to detect the malware as the encrypted code appears as random data. Additionally, malware creators often use rootkit techniques to hide the presence of the malware in the system, making it even more challenging for antivirus software to detect and remove the malicious code.
