• Viruses and worms share some very common characteristics, primarily that thay are designed to infect as many computers as they can, as fast as they can. The key difference is in the way they do it. A worm usually infects a computer through flaws in the operating system and needs no human interaction, whereas a virus does.
• Trojan Horses are also common, just like the Greek myth, a Trojan Horse pretends to be something it isn't - seemingly useful software or files hide malicious code. The most common form of Trojan Horse is the backdoor. An infected computer creates a way in for the coder where they can infect your computer system with a virus or install software known as a "keylogger" to capture vital business & personal data.

All three can be destructive, and can bring down whole networks of computers.

• Spyware and adaware are also unwanted and intrusive but they are never destructive to your computer system. They are designed to spy on your computer usage and send the information back to their originators. 

The information captured can be used either as a way of advertising (adaware) or for spying on your internet browsing habits and more worryingly gather personal information, such as passwords, bank account details and credit card information.
