Using the latest software version makes your computer more secure. Always register your software for support – and subscribe to alert and update services.
You can buy software that protects your computer against viruses and spyware (computer programs that track what you're doing on the internet). Set the software to scan files when you access them – and to download updates when you go online.
A firewall is a piece of software that acts as a barrier between your computer and the internet to block unauthorised access and viruses. You might have firewalls built into your computer system – or included in an internet security software package. Keeping firewall software up to date will protect your computer from the latest security threats.
If you're planning to use a wireless network to access the internet, follow the manufacturer's instructions on how to set it up securely with encryption and access controls.
