How can malware be disguised to evade detection by antivirus software?
Malware can be disguised by using techniques such as code obfuscation, polymorphism, and encryption. Code obfuscation involves modifying the code to make it difficult for antivirus programs to analyze and detect. Polymorphism involves constantly changing the appearance of the malware by altering its code structure or behavior. Encryption involves encrypting the malware code so that it can only be decrypted and executed at runtime, making it harder for antivirus software to detect.
To evade detection by antivirus software, malware can be disguised by using techniques such as rootkit installation, which allows the malware to hide itself deep within the operating system and evade detection. Additionally, malware creators can use packers or crypters to compress and encrypt the malware code, making it difficult for antivirus software to analyze and detect. By utilizing these techniques, malware can successfully remain undetected and carry out its malicious activities without being detected by antivirus programs.
