Malware is the general term for any malicious or unwanted software or code. Malware includes the following:
- Viruses—programs that attach themselves to your data or software
- Spyware—tries to get onto your computer without your knowledge and monitor your activities
- Trojans—similar to a virus but masquerade as something else, such as a game
- Rootkits—very hard to get rid of infections that modify deep levels of your computer's operating system. They allow malware to attack or infect your computer
- Worms—programs that multiply once they get onto your computer. They are annoying but not usually deliberately destructive
- Ad-ware—displays unwanted advertising, for example you might open your browser and an ad will appear instead of your homepage
- Scareware—uses social engineering techniques to cause shock or anxiety and trick users into purchasing unnecessary products (e.g. fake anti-virus software)
- Ransomware—malicious software that blocks access to your computer system until a sum of money is paid
