How do I know if my phone or computer has a virus or has been hacked?

Look for unusual slowdowns, pop-ups, unknown apps or account activity, then scan and change passwords.

Warning signs include sudden slowdowns, unexpected pop-ups, apps you do not recognise, fast battery drain, high data use and unfamiliar activity on your accounts. None proves a problem alone, but several together are worth checking.

Act quickly if you think you are affected.

What to do

Install updates, remove unknown apps and run a scan with a reputable security tool. On computers, use the built-in or a trusted anti-malware program.

Secure your accounts

From a clean device, change passwords for your email, banking and important accounts, and turn on 2FA.

If it persists

Back up your files and restore the device to factory settings. If money or identity details may be at risk, contact your bank and the relevant authorities.
