How to remove self-installed malware from Android devices?

I have heard that there is a new type of malware that can download, install, and delete applications from the device and disappear when the device is turned on. In addition, the malware components will remain in the device. After the device restarts, it will be re-installed. How does this malware work? How should we eradicate it? Is there a way to get rid of it completely?
