Even if you have the setting on auto-updates, make a habit in manually forcing your App store (iOS or Android) to download & install updates for all your installed applications.
The speed of spreading the malware is incredible and sometimes, many times in fact, patches are released with immediate application.
Do it one time, two times a week. It takes few seconds to see if your Apps or iOS/macOS/Android/Windows is up-to date.
Seconds which may save your virtual life. And sometimes, your real life too.
