If your computer isn't secure, losing your data could be the least of your worries. There are a number of steps you can take to increase the security of your computer or laptop. Keeping software up to date can protect it from online attacks.

• Firewall - control the information that comes into (and leaves) your PC.
• Anti-virus - put your computer on guard against attacks, and cure any infections.
• Anti-spyware - stop unauthorised software snooping on details such as your passwords.
