When accessing the Internet, it is important to be aware of Internet Security issues such as viruses, hackers, and privacy threats. Optus takes steps to help minimise internet security issues on our network, but we also need our customers to take steps to protect themselves and their computers from unauthorised access. There are several things you can do to protect yourself from such threats, as shown below.

Install security software and keep it updated

Many security solutions include components such as firewalls, anti-virus, content filters, anti-spyware and spam filters. Details on these components can be found below*.

Families with kids who use the Internet can also use a content filter solution to manage the type of content their kids can access.

You should ensure your security software is up-to-date with the latest fixes, so you may wish to allow the security software to automatically update itself.

Optus Security provides a security solution for Optus customers protecting against virus, spyware and spam attacks. For details go to

Take action immediately if you suspect your computer has been compromised

Report any unauthorised access to the police. Change your passwords immediately and contact your bank if you suspect personal financial information has been stolen.

Use strong passwords

Choose passwords that are not easy to guess, and change your passwords regularly.

Stop and think before sharing information or clicking on links and attachments

Be careful about the personal or financial information you share with people online.

Don't open suspicious emails or attachments from unknown sources, and don't click on links in emails that request your personal details.


When online your computer is potentially vulnerable to malicious Internet users. A Firewall is software and/or hardware used to protect one or more computers connected to the Internet from hackers and other unwanted intrusions.


A computer virus is a program or piece of malicious code that can have many negative effects on your computer. Protecting your computer against viruses is easy with Antivirus software.

Content Filtering

Content filtering software helps you control the content accessed from your computer. It can be used to restrict and monitor Web sites, Email, Chat, IM and newsgroups that may be offensive and/or inappropriate for children. The Internet Industry Association has approved a list of Internet Content Filters which have been independently tested and meet the criteria outlined in the IIA content code.

Spyware and Adware

Adware, also known as an Adbot, can profile your online surfing and spending habits and pop up those annoying ad windows. Spyware, also known as Malware, is potentially far more dangerous than Adware because it can record your keystrokes, history, passwords and other confidential and private information.

Spam Filters

"Spam" is unwanted and unsolicited junk email on the Internet. The Spam Act 2003 was established to regulate spam (defined as an 'unsolicited commercial electronic message') sent to or by Australian end users. Optus Internet offers a FREE Spam Filter for all Optus email accounts.
