What are some common techniques used by malware to evade detection by antivirus software?

### REPLY:
One way to evade detection by antivirus software is by using a specific vulnerability present in a widely used antivirus program. By exploiting this vulnerability, the malware can bypass the antivirus software without detection. Another technique is to use a Trojan horse to disguise the malware as a legitimate software update, tricking the user into installing it unknowingly.
