Jack’s computer has been running very slowly for a few days, and eventually he asks his friend to take a look at it for him. His friend downloads the latest version of an antivirus software program, which finds a virus on Jack’s computer. Jack remembers downloading an email attachment received from his sister just before the computer began to slow down. When he searches through his sent messages, he discovers that the file has sent itself on to all of his contacts.

He wonders why anyone would create such a malicious file, and what they have to gain from infecting his computer.
