Protect your computer with anti-virus software

Essential protection for your computer

Malicious software (or ‘malware’) is software that has been created to reduce the security of your computer. Malware can cause your computer to stop working correctly, perform tasks without you knowing, or allow other people to access your computer - giving them access to your information and online accounts.

Your computer can become infected with malicious software by:

  • Clicking on links or opening attachments in phishing emails
  • Visiting websites that are infected with malware
NAB strongly recommends that all computers and devices have up-to-date anti-virus software.

Anti-virus software is designed to identify and remove malware from a computer. In order to be effective, anti-virus software must be kept up-to-date. You can set your anti-virus to update automatically to protect your device from new threats.

You can learn about more about anti-virus software on the Australian Government’s Stay Smart Online website.
