Example, Max uses USB flash to copy some documents from his friend computer (his friend computer already infected by viruses). When Max insert USB flash drive to the computer, most viruses will immediately copy itself to the flash (it is fast, you cannot even see the process because virus is very small executable file). After inserted his flash, now it contains the viruses. Max computer is easily infected by viruses in his USB flash if there is no effective antivirus installed in his computer.

Another popular mean that viruses can spread themselves into many computers (can be millions) around the world is through E-mail Attachment. As E-mail is very popular and useful for daily life, many people are using it. Many virus creators see that it is a great mean and opportunity to spread their viruses using E-mail.
