Malware on your device.

Malware ‘infects’ computer systems, including mobile devices such as phones and tablets, through human intervention via email, apps or websites. Once your device is infected, the malware can cause damage.

Following the Australian Communication and Media Authority guidelines, we provide malware notifications for our customers.

If you have malware on your mobile device with a Vodafone SIM, or a laptop that you’ve tethered to a Vodafone device, we’ll send you a SMS to let you know that you’ve been infected and explain what to do next.

SMS notifications will be sent between 11am and 5pm AEST/AEDT.

How to remove malware from your device.

Step 1: Back up your device’s content and data including contacts, photos and media. Check out our interactive user guides for instructions. Computers and laptops require a system backup.

Step 2: Complete a factory reset of your mobile device. Check out our interactive user guides for instructions. Anti-virus software should be used on computers and laptops.

Steps to help avoid getting infected by malware.

How will I know if I have malware?

Common types of malware.

Adware.

Adware works with existing software to display advertising, like a tool bar in your computer internet browser. These tool bars usually provide features like internet searches or links to specific websites, and display ads constantly.

Adware is usually harmless and requires you to install it, but it’s important to be aware that they may sometimes act as spyware. Many free apps display advertisements. This is not adware and won’t affect you if you don’t click them.

Keylogger.

Keyloggers monitor and record input from your keyboard. Advanced keylogger infections can record mouse clicks, take screen shots, and record audio/video with your webcam. These records are then stored on your device so that they can be retrieved later, or forwarded to someone else online.

Spyware.

Spyware 'spies' on your device by collecting things like internet browser history, downloads records, password and personal data. It then forwards the data to someone else online. Spyware can spread through email attachments or be part of another program's installation file. This process can happen without you knowing.

Trojan horse.

A Trojan horse creates a 'back door' in a computer or device's security, allowing others easy access to your personal data. Unlike other Malware, Trojans need your help to spread. A common way they spread is through email attachments and file sharing sites. If you don’t open the attachment or install the program, they can’t get in. Trojans can also do more complex tasks, similar to viruses, like deleting files or spreading other viruses once they're in your system.

Virus.

A virus is malware that spreads by copying itself into other software. It can spread through networked computers, over the internet and on USB flash drives. Their effects range from freezing your device and closing applications, to overwriting and deleting your personal data. Viruses usually come in the form of an executable file (or ‘.exe’) and stay in hiding on your device until you unknowingly open or run it.

Worm.

Worms are similar to viruses. They can take control of computer systems, rewrite or delete data and copy themselves into other programs. They don’t need your help to spread and can copy themselves into communication software like your email software or instant messenger to travel through networks and the internet to other devices.
