When installing apk/apps, you may and will be asked to allow to install from unknown sources.
An on-screen prompt may show you the way to get to this option.
Or you can follow the path shown below.
Home Screen > Settings > Device Preferences > Security and Restrictions > Unknown Sources

In here we can also turn 'Verify Apps' on or off. This is a built in function that will do a quick and basic scan on the app to be installed.
