Some common techniques used for evading antivirus detection include using packers and crypters to obfuscate the malware code and make it difficult for antivirus software to detect. Another method is polymorphism, where the malware code is constantly changing to create new variants that are not recognized by antivirus signatures. Attackers may also use rootkit techniques to hide the presence of malware on the infected system, making it harder for antivirus software to detect and remove.
