What is a Malware?

Malware, short for malicious software, is a common method fraudsters use to access your devices, service or network. This data could be anything from banking details, healthcare records, personal emails to passwords. Malware is often hidden in links or attachments, sent in emails or SMS, but can also be downloaded via malicious advertisements, unauthorised software installations or even infected apps.

Viruses, trojans, spyware and ransomware are all types of malware.

Signs and example* of Malware

  • Your browser redirects your searches.
  • Frequent pop-up warnings.
  • Your device is slow.
  • Important information changes such as payment details or transfers to a new payee.


Take your device to a professional IT technician for assistance.

Sarah received a parcel delivery notification via email. Having recently purchased several items online, she assumed it was related to one of these.


Sarah clicked on the tracking link in the email, but the page did not load. She clicked the link again but still could not get the page to load.


Sarah decided to go directly to her AustPost account to check the details and saw there was nothing listed for delivery today. She presumed the email had been sent in error.


Over the next couple of days, Sarah noticed her computer was running slower than usual, which was becoming frustrating as she had several payments she needed to make for her small business.


Shortly after, Sarah signed into online banking and found her access had been suspended. She contacted the bank and was advised by their fraud team that there was suspected malware on her device. After confirming the transactions she had performed that day, they noticed one of the payee accounts had been amended. Luckily for Sarah, the bank had stopped the processing of that payment, due to the discrepancy. Sarah followed the banks instructions to assist in removing the malware from her device.

Common ways malware may be downloaded to your device

An email/text asks you to open an attachment or has a link to a website.

Be wary. Is it from their usual address something they would usually send, does it feel right, and does the link address look right?

An internet site offers free software, games, music, movies or videos.

Be wary. These sites may load malicious software onto your device.

Someone contacts you unexpectedly and asks you to download software.

Do not follow their directions, download any software or give someone access to your device.
