How can malware be disguised to evade detection by antivirus software?
Malware can be disguised to evade detection by antivirus software using various techniques. One common method is through code obfuscation, which involves modifying the code to make it more difficult for antivirus programs to recognize and analyze. Another technique is polymorphism, where the malware changes its code structure each time it infects a new system, making it harder to detect. Encryption is also used to encrypt the malware code, making it unreadable by antivirus software until it is decrypted at runtime.
One effective way to disguise malware to evade detection by antivirus software is by using rootkit techniques. A rootkit is a set of tools that allows an attacker to gain unauthorized access to a system and maintain control over it while hiding their presence. By installing a rootkit, the attacker can hide the malware from antivirus software, making it difficult to detect and remove.
