I found a post "Android Installer Hijacking Vulnerability" and then installed an app 'Installer Hijacking Scanner' from Palo Alto Networks and tested my device for vulnerability.
Some other people also found their phone safe and some do not.

What is this Android Installer Hijacking and how to fix phones infected with it.
Please suggest a solution for all possible versions of android.
Is it there an 'Installer Hijacking Defender' or 'Protector' that could help me?
