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.

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.
