'Request Install Packages' let's say if an app has this permission ex- facebook(Check it in playstore head to facebook then 'app permissions' and click 'see more'. I used to read articles related to security threads to the device and while reading what this permission can bring to the device is look suspicious as it can trigger to install/make change to an existing app silently(without taking any permission from user).
I have then checked many apps that i was going to install but this setting makes me think that it may include security issues. Isn't it ?
Is there any way to prevent making changes silently ? Can an antivirus prevent these changes to the device's app ?
