How can malware evade detection by antivirus software?
Malware can evade detection by antivirus software by using techniques such as polymorphism, which involves constantly changing its code signature to avoid pattern-based detection. It can also use encryption to hide its malicious payload and make it difficult for antivirus scanners to detect. Additionally, malware can employ rootkit techniques to hide its presence and evade detection by altering system calls and processes.
One way malware can evade detection is by exploiting vulnerabilities in the antivirus software itself. By exploiting these vulnerabilities, the malware can disable or bypass the antivirus software altogether. Another technique is to use packers or crypters that encrypt the malware code, making it difficult for antivirus scanners to analyze and detect. Some malware may also use techniques like hooking or DLL injection to intercept and manipulate antivirus software's behavior, allowing it to remain undetected.
