2. Spyware: A program that spies on you and potentially sends information from your hard drive to remote locations.
3. Adware: Software that shows advertisements.
4. Trojan Horse: A malicious program that acts as something else to gain access to your computer.

In broader terms, malware is anything that connects to the Internet without your knowledge and approval or that displays something unintentional.
