What is Malware?
Malware (malicious software) is any program designed to harm, exploit or gain unauthorised access to computers, networks or data. Common forms include viruses, trojans, spyware, worms and ransomware, and it typically arrives via email attachments, malicious links or compromised websites.
Why Malware matters for Australian businesses
With cyberattacks on Australian businesses increasing year on year, understanding your security tools and strategies is critical. The Australian Cyber Security Centre reports an attack every six minutes, and small and medium businesses are increasingly targeted. Having the right defences in place is not optional — it is essential for protecting your data, your clients, and your reputation.
For small and medium businesses in particular, understanding malware is essential to maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current defences or planning improvements, knowing how these threats work and how to stop them will help you have more informed conversations with your IT provider and make better decisions for your business.
