Updates can fix security weaknesses in software.
Read the video transcript
A software update can repair a security weakness in an app or device. A weakness is a mistake that someone might use to get access they should not have.
Imagine a window that does not close properly. Fixing the latch closes that gap. An update can do something similar for software, although the real repair is a change to its code.
Use the update option inside your device settings or the app itself. A frightening message on a random website is not a trustworthy way to find an update.
Turn on automatic updates where they are available. Some repairs only finish after a restart, so do not keep putting off that final step when your device asks for it.
Updates reduce risk, but they do not make every message or download safe. The simple habit is to let supported software receive its repairs, using the update tools that belong to it.

The short answer
A software update can repair a security weakness in an app or device. A weakness is a mistake that someone might use to get access they should not have.
A simple example
Imagine a window that does not close properly. Fixing the latch closes that gap. An update can do something similar for software, although the real repair is a change to its code.
Use the update option inside your device settings or the app itself. A frightening message on a random website is not a trustworthy way to find an update.
Turn on automatic updates where they are available. Some repairs only finish after a restart, so do not keep putting off that final step when your device asks for it.
Updates reduce risk, but they do not make every message or download safe. The simple habit is to let supported software receive its repairs, using the update tools that belong to it.
Put it into practice
- Find the update controls in your device settings or the app itself.
- Enable automatic updates where available.
- Finish any requested restart so the repair can take effect.
Check your understanding
A random web page says your device is infected and offers an update. Should you install it?
Answer
No. Open the device’s own update settings or the app’s trusted update tool instead.
