The basics remain the most important
Most security issues start with fake links, suspicious attachments, reused passwords or out-of-date systems. Before installing any more programmes, check that Windows, macOS, your browser and your antivirus software are up to date.
Warning signs
- Windows opening by themselves or unusual adverts.
- Your computer running very slowly for no apparent reason.
- Emails asking for urgent action, payment or confirmation of details.
- Websites that look like those of banks, transport companies or well-known services, but with a strange web address.
If in doubt, don’t click. It’s better to check first than to have to recover your data later.
Simple best practices
Use different passwords, enable two-step verification wherever possible and make backups. If you suspect an infection, disconnect from the internet and seek a diagnosis before trying random tools.
