Malware and Viruses
Viruses and malware are programs that can damage digital devices such as phones, tablets, computers or watches. A virus is a small program designed to cause trouble by gaining access to your device. It can copy your personal data or slow your device down. A virus spreads by duplicating and attaching itself to other files.
By combining the words ‘malicious’ (meaning ‘harmful’) and ‘software’ we get the word ‘malware’. Viruses are just one type of malware. Other types include spyware, worms and trojans.
What can happen to your device?
Malware is made to stop your device from running properly and sometimes to steal your information.

How can you prevent this?
You have to be smart when using your device. When using the web or email don’t click on anything unless you know what it is. Check if it is an email you’re expecting from an address you recognise or it is a site that you’re sure you can trust. Install anti-virus software* and run regular scans**. This will highlight any suspicious software.
