General App Question - After Removing

[Cold Sunshine]

Hey All,

First time posting here, so please be gentle .

I just removed an app and everything went fine but it got me thinking. Is there a way to be sure that no malware, etc. was installed from a third-party app installed? Also, when you go into the settings and then filter the apps by "third party" will this show all non-stock apps that I have installed including any malware, etc.? Or can malware still be hiding elsewhere, and if so where should I look?

Thanks, everyone.
