If your phone or laptop behaves strangely, treat it as a security warning until you understand the cause. Some symptoms are normal software faults, but account alerts, unknown apps, pop-ups and payment concerns need quick action.

  1. Secure accounts from another trusted device.Change email, Apple ID, Google and banking passwords from a safe device if you suspect compromise.
  2. Check linked devices and sessions.Remove anything you do not recognise from WhatsApp, Google, Apple, email and social accounts.
  3. Update and remove suspicious items.Update software, remove unknown apps/profiles/extensions and do not install anything from pop-ups.
  4. Contact your bank if money is involved.TECHHELP can check the device, but banks handle payment fraud and chargeback investigation.
