How can malware evade detection by antivirus software?
Malware can evade detection by antivirus software through techniques such as code obfuscation, polymorphism, and encryption. It can also employ rootkit functionality to hide its presence on a system or use packers to compress and encrypt its code, making it harder for antivirus programs to detect.
To evade detection by antivirus software, malware can exploit vulnerabilities in the antivirus software itself, disable or modify security features, or even masquerade as legitimate system files or processes. It can also use sophisticated anti-analysis techniques, like sandbox evasion or detecting virtual machine environments, to avoid detection and analysis by security researchers.
