How can malware be disguised to avoid detection by antivirus software?
Malware can be disguised to avoid detection by antivirus software through various techniques such as code obfuscation, polymorphism, and encryption. Code obfuscation makes the code harder to understand and analyze, while polymorphism alters the structure of the code each time it is executed. Encryption can be used to encrypt the malware payload, making it difficult for antivirus software to detect.
One effective way to disguise malware and avoid detection by antivirus software is by using rootkit techniques. A rootkit is a collection of tools and techniques that enable unauthorized access to a computer system. It can hide malicious software and processes, making it extremely difficult for antivirus software to detect or remove them.
