How to track a virus infection on Android?

Question

Android

I caught a small infection on the tablet by accidentally clicking on an ad. Vir changes the browser's start page to a link that redirects to the playmarket, I advertise some applications, although the home page in the browser is completely different. Well, okay, it is treated in a couple of minutes, but it became interesting.
The essence of the question: I have a malicious link, is it possible to track exactly how the infection occurs? There is a guinea pig in the face of the tablet, but solutions for the emulator are also suitable.
