What is malware?

Malware is short for ‘malicious software’, and similarly to ‘spyware’, is a term to describe unauthorised programs that are downloaded to your computer and cause disruption or damage to software or hardware. Sometimes, malware is designed to use your computer’s ‘resources’ (such as memory) and other times it is simply designed to create an unpleasant experience. Malware can be accidentally downloaded through spam emails, or when downloading files from untrustworthy websites, such as file-sharing websites.
