What are some common evasion techniques used by malware to bypass antivirus software?

### REPLY:
Malware developers employ various evasion techniques to bypass antivirus software. One common technique is code obfuscation, where the malware's code is modified to make it harder to analyze and detect. Another technique is polymorphism, where the malware continually changes its code to create unique variants that can evade detection. Additionally, attackers may use rootkit techniques to hide the presence of malware by modifying the operating system or kernel. These techniques are constantly evolving as antivirus software improves, so it is important to stay updated on the latest security measures.
