Can you explain how malware can evade detection by antivirus software?
Malware can employ various techniques to evade antivirus detection, such as code obfuscation, polymorphism, and using packers or crypters. These methods make it harder for antivirus software to recognize the malicious code and prevent its execution.
One method to evade antivirus detection is by using rootkit techniques, where malware gains administrator-level access and modifies the operating system to hide its presence. Another approach is to encrypt the malware code, making it difficult for antivirus software to analyze and identify it. Advanced malware can also use fileless techniques, running directly in memory without leaving traces on the file system, making it harder to detect and eliminate.
