1. A virus writer sends out viruses, infecting ordinary users' PCs. 2. Infected PCs log into an IRC server or other communications medium, without their owners knowing, forming a network of infected systems known as a botnet. 3. A spammer purchases access to this botnet from virus writer or a dealer. 4. The spammer sends instructions to the botnet, instructing the infected PCs to send out spam. 5. The infected PCs send the spam messages to internet users' mail servers.

The diagram is for use when educating classes about the importance of keeping computers virus-free. It can also be used to explain to learners why it is that so much spam is received in their mailboxes and why unidentified attachments should not be opened. ਇੱਕ ਫੁੱਲ-ਸਾਈਜ਼ ਵਰਜ਼ਨ ਲਈ ਤਸਵੀਰ ਉੱਤੇ ਕਲਿੱਕ ਕਰੋ, ਜਿਸ ਨੂੰ ਤੁਸੀਂ ਅਜ਼ਾਦੀ ਨਾਲ ਪੁਨਰ-ਵਰਤੋਂ ਕਰ ਸਕੋ ਅਤੇ ਸੁਧਾਰ ਸਕੋ. ਇਸਦੇ ਵਰਗੀਆਂ ਹੋਰ ਤਸਵੀਰਾਂ ਪ੍ਰਾਪਤ ਕਰਨ ਵਾਸਤੇ ਹੇਠਾਂ ਵਾਲੇ ਲਿੰਕ ਤੇ ਕਲਿੱਕ ਕਰੋ
