Your computer can be infected by malware in a number of ways, including:
- clicking on false website links
- visiting websites that have been infected by malware
- downloading infected apps and files from the internet
- opening infected email attachments.
When you first install anti-virus software on a device, run a 'full scan' of the system to ensure there are no pre-existing virus infections, and then set up regular scans.
Important: Install anti-virus software on all devices and set the software to automatically check for updates on a daily basis.
