Safe downloads, updates and antivirus — Cyber safety for kids

Harmful programs often hide in “free” copies of paid games, mods, pop-up downloads and unknown attachments. Download only from the official app store or a trusted site, ask a parent before installing, read the permissions an app asks for (a calculator does not need your contacts), install updates — they fix security holes — and keep antivirus or security protection switched on.

Stay safe

Official, updated, protected — “get apps from official stores, update them and keep protection on”

  1. Install from the official app store or a trusted site, and ask a parent first.
  2. Check permissions: does the app need it to do its job? A torch app reading messages is a warning sign.
  3. Install updates soon; keep antivirus on; never open unknown attachments or tap “your phone has viruses” pop-ups.

Use it for: Installing games and apps, opening attachments and seeing update messages or pop-ups.

Worked example: 🔐 Does this permission make sense, or is it a warning sign? A calculator app asks for your contacts. → a warning sign

  1. A calculator does not need your contacts to do sums.
  2. So it is a warning sign.

Check: Try it: with a parent, check one device for pending updates and look at the permissions of one app ✓
