Is it necessary to install antivirus software on Android?

Anti-virus software needs to be installed, but now the general brand mobile phones have built-in security programs, so it is not necessary to install them. For example, Xiaomi, Meizu and Huawei have built-in security software, so download it. If the original sound system does not have the prospect of its own security software, download some antivirus software such as 360 and install it to ensure the security of the system.
