Living with the internet: Keeping it safe

2 Viruses, worms and Trojans

2.1 What is a virus?

A virus is a piece of computer code – a program – that has been written to gain access to files or programs on your computer. The virus may enter your computer via floppy disk, by email or by your Internet connection. It will look at the files on your computer and infect some of them if it can.
